General

Description

Altera’s FLEX 10K devices are the industry’s first embedded PLDs. Based

on reconfigurable CMOS SRAM elements, the Flexible Logic Element

MatriX (FLEX) architecture incorporates all features necessary to

implement common gate array megafunctions. With up to 250,000 gates,

the FLEX 10K family provides the density, speed, and features to integrate

entire systems, including multiple 32-bit buses, into a single device.

FLEX 10K devices are reconfigurable, which allows 100

testing prior to

shipment. As a result, the designer is not required to generate test vectors

for fault coverage purposes. Additionally, the designer does not need to

manage inventories of different ASIC designs; FLEX 10K devices can be

configured on the board for the specific functionality required.

Table 6 shows FLEX 10K performance for some common designs. All

performance values were obtained with Synopsys DesignWare or LPM

functions. No special design technique was required to implement the

applications; the designer simply inferred or instantiated a function in a

Verilog HDL, VHDL, Altera Hardware Description Language (AHDL), or

schematic design file.

Notes:

(1) The speed grade of this application is limited because of clock high and low specifications.

(2) This application uses combinatorial inputs and outputs.

(3) This application uses registered inputs and outputs.

FLEX 10K Embedded Programmable Logic Family Data Sheet

The FLEX 10K architecture is similar to that of embedded gate arrays, the

fastest-growing segment of the gate array market. As with standard gate

arrays, embedded gate arrays implement general logic in a conventional

“sea-of-gates” architecture. In addition, embedded gate arrays have

dedicated die areas for implementing large, specialized functions. By

embedding functions in silicon, embedded gate arrays provide reduced

die area and increased speed compared to standard gate arrays. However,

embedded megafunctions typically cannot be customized, limiting the

designer’s options. In contrast, FLEX 10K devices are programmable,

providing the designer with full control over embedded megafunctions

and general logic while facilitating iterative design changes during

debugging.

Each FLEX 10K device contains an embedded array and a logic array. The

embedded array is used to implement a variety of memory functions or

complex logic functions, such as digital signal processing (DSP),

microcontroller, wide-data-path manipulation, and data-transformation

functions. The logic array performs the same function as the sea-of-gates

in the gate array: it is used to implement general logic, such as counters,

adders, state machines, and multiplexers. The combination of embedded

and logic arrays provides the high performance and high density of

embedded gate arrays, enabling designers to implement an entire system

on a single device.

FLEX 10K devices are configured at system power-up with data stored in

an Altera serial configuration device or provided by a system controller.

Altera offers the EPC2, EPC1, and EPC1441 configuration devices, which

configure FLEX 10K devices via a serial data stream. Configuration data

can also be downloaded from system RAM or from Altera’s BitBlaster

serial download cable, ByteBlaster

parallel port download cable, or

ByteBlasterMV

parallel port download cable (the ByteBlaster cable is

obsolete and is replaced by the ByteBlasterMV cable, which can program

or configure 2.5-V, 3.3-V, and 5.0-V devices). After a FLEX 10K device has

been configured, it can be reconfigured in-circuit by resetting the device

and loading new data. Because reconfiguration requires less than 320 ms,

real-time changes can be made during system operation.

FLEX 10K devices contain an optimized interface that permits

microprocessors to configure FLEX 10K devices serially or in parallel, and

synchronously or asynchronously. The interface also enables

microprocessors to treat a FLEX 10K device as memory and configure the

device by writing to a virtual memory location, making it very easy for the

designer to reconfigure the device.

Application Note 59 (Configuring FLEX 10K Devices)

FLEX 10K devices are supported by Quartus and MAX+PLUS II

development systems; a single, integrated package that offers schematic,

text (including AHDL), and waveform design entry, compilation and

logic synthesis, full simulation and worst-case timing analysis, and device

configuration. The Quartus and MAX+PLUS II software provides

EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL, and other interfaces for

additional design entry and simulation support from other industry-

standard PC- and UNIX workstation-based EDA tools.

The Quartus and MAX+PLUS II software works easily with common gate

array EDA tools for synthesis and simulation. For example, the

MAX+PLUS II software can generate Verilog HDL files for simulation

with tools such as Cadence Verilog-XL. Additionally, the Quartus and

MAX+PLUS II software contains EDA libraries that use device-specific

features such as carry chains which are used for fast counter and

arithmetic functions. For instance, the Synopsys Design Compiler library

supplied with the Quartus and MAX+PLUS II development systems

include DesignWare functions that are optimized for the FLEX 10K

architecture.

The MAX+PLUS II development system runs on Windows-based PCs and

Sun SPARCstation, HP 9000 Series 700/800, and IBM RISC System/6000

workstations, and the Quartus development system runs on Windows-

based PCs and Sun SPARCstation and HP 9000 Series 700 workstations.

MAX+PLUS II Programmable Logic Development System & Software

Data Sheet

for more information.

Functional

Description

Each FLEX 10K device contains an embedded array to implement

memory and specialized logic functions, and a logic array to implement

general logic.

The embedded array consists of a series of EABs. When implementing

memory functions, each EAB provides 2,048 bits, which can be used to

create RAM, ROM, dual-port RAM, or first-in first-out (FIFO) functions.

When implementing logic, each EAB can contribute 100 to 600 gates

towards complex logic functions, such as multipliers, microcontrollers,

state machines, and DSP functions. EABs can be used independently, or

multiple EABs can be combined to implement larger functions.

8 Altera Corporation

FLEX 10K Embedded Programmable Logic Family Data Sheet

The logic array consists of logic array blocks (LABs). Each LAB contains

eight LEs and a local interconnect. An LE consists of a 4-input look-up

table (LUT), a programmable flipflop, and dedicated signal paths for carry

and cascade functions. The eight LEs can be used to create medium-sized

blocks of logic—8-bit counters, address decoders, or state machines—or

combined across LABs to create larger logic blocks. Each LAB represents

about 96 usable gates of logic.

Signal interconnections within FLEX 10K devices and to and from device

pins are provided by the FastTrack Interconnect, a series of fast,

continuous row and column channels that run the entire length and width

of the device.

Each I/O pin is fed by an I/O element (IOE) located at the end of each row

and column of the FastTrack Interconnect. Each IOE contains a

bidirectional I/O buffer and a flipflop that can be used as either an output

or input register to feed input, output, or bidirectional signals. When used

with a dedicated clock pin, these registers provide exceptional

performance. As inputs, they provide setup times as low as 1.6 ns and

hold times of 0 ns; as outputs, these registers provide clock-to-output

times as low as 5.3 ns. IOEs provide a variety of features, such as JTAG

BST support, slew-rate control, tri-state buffers, and open-drain outputs.

Figure 1 shows a block diagram of the FLEX 10K architecture. Each group

of LEs is combined into an LAB; LABs are arranged into rows and

columns. Each row also contains a single EAB. The LABs and EABs are

interconnected by the FastTrack Interconnect. IOEs are located at the end

of each row and column of the FastTrack Interconnect.

Altera Corporation 9

FLEX 10K Embedded Programmable Logic Family Data Sheet

Figure 1. FLEX 10K Device Block Diagram

FLEX 10K devices provide six dedicated inputs that drive the flipflops’

control inputs to ensure the efficient distribution of high-speed, low-skew

(less than 1.5 ns) control signals. These signals use dedicated routing

channels that provide shorter delays and lower skews than the FastTrack

Interconnect. Four of the dedicated inputs drive four global signals. These

four global signals can also be driven by internal logic, providing an ideal

solution for a clock divider or an internally generated asynchronous clear

signal that clears many registers in the device.

Embedded Array Block

The EAB is a flexible block of RAM with registers on the input and output

ports, and is used to implement common gate array megafunctions. The

EAB is also suitable for functions such as multipliers, vector scalars, and

error correction circuits, because it is large and flexible. These functions

can be combined in applications such as digital filters and

microcontrollers.

FLEX 10K Embedded Programmable Logic Family Data Sheet

Logic functions are implemented by programming the EAB with a read-

only pattern during configuration, creating a large LUT. With LUTs,

combinatorial functions are implemented by looking up the results, rather

than by computing them. This implementation of combinatorial functions

can be faster than using algorithms implemented in general logic, a

performance advantage that is further enhanced by the fast access times

of EABs. The large capacity of EABs enables designers to implement

complex functions in one logic level without the routing delays associated

with linked LEs or field-programmable gate array (FPGA) RAM blocks.

For example, a single EAB can implement a 4

4 multiplier with eight

inputs and eight outputs. Parameterized functions such as LPM functions

can automatically take advantage of the EAB.

The EAB provides advantages over FPGAs, which implement on-board

RAM as arrays of small, distributed RAM blocks. These FPGA RAM

blocks contain delays that are less predictable as the size of the RAM

increases. In addition, FPGA RAM blocks are prone to routing problems

because small blocks of RAM must be connected together to make larger

blocks. In contrast, EABs can be used to implement large, dedicated

blocks of RAM that eliminate these timing and routing concerns.

EABs can be used to implement synchronous RAM, which is easier to use

than asynchronous RAM. A circuit using asynchronous RAM must

generate the RAM write enable (

) signal, while ensuring that its data

and address signals meet setup and hold time specifications relative to the

signal. In contrast, the EAB’s synchronous RAM generates its own

signal and is self-timed with respect to the global clock. A circuit using the

EAB’s self-timed RAM need only meet the setup and hold time

specifications of the global clock.

When used as RAM, each EAB can be configured in any of the following

sizes: 256

8, 512

4, 1,024

2, or 2,048

1. See Figure 2.

256 × 8 512 × 4 1,024 × 2 2,048 × 1

Altera Corporation 11

FLEX 10K Embedded Programmable Logic Family Data Sheet

Larger blocks of RAM are created by combining multiple EABs. For

example, two 256

8 RAM blocks can be combined to form a

256

16 RAM block; two 512

4 blocks of RAM can be combined to form

a 512

8 RAM block. See Figure 3.

Figure 3. Examples of Combining EABs

If necessary, all EABs in a device can be cascaded to form a single RAM

block. EABs can be cascaded to form RAM blocks of up to 2,048 words

without impacting timing. Altera’s MAX+PLUS II software automatically

combines EABs to meet a designer’s RAM specifications.

EABs provide flexible options for driving and controlling clock signals.

Different clocks can be used for the EAB inputs and outputs. Registers can

be independently inserted on the data input, EAB output, or the address

and

inputs. The global signals and the EAB local interconnect can drive

the

signal. The global signals, dedicated clock pins, and EAB local

interconnect can drive the EAB clock signals. Because the LEs drive the

EAB local interconnect, the LEs can control the

signal or the EAB clock

signals.

Each EAB is fed by a row interconnect and can drive out to row and

column interconnects. Each EAB output can drive up to two row channels

and up to two column channels; the unused row channel can be driven by

other LEs. This feature increases the routing resources available for EAB

outputs. See Figure 4.

Each LAB provides four control signals with programmable inversion

that can be used in all eight LEs. Two of these signals can be used as

clocks; the other two can be used for clear/preset control. The LAB clocks

can be driven by the dedicated clock input pins, global signals, I/O

signals, or internal signals via the LAB local interconnect. The LAB preset

and clear control signals can be driven by the global signals, I/O signals,

or internal signals via the LAB local interconnect. The global control

signals are typically used for global clock, clear, or preset signals because

they provide asynchronous control with very low skew across the device.

If logic is required on a control signal, it can be generated in one or more

LEs in any LAB and driven into the local interconnect of the target LAB.

In addition, the global control signals can be generated from LE outputs.

Logic Element

The LE, the smallest unit of logic in the FLEX 10K architecture, has a

compact size that provides efficient logic utilization. Each LE contains a

four-input LUT, which is a function generator that can quickly compute

any function of four variables. In addition, each LE contains a

programmable flipflop with a synchronous enable, a carry chain, and a

cascade chain. Each LE drives both the local and the FastTrack

Interconnect. See Figure 6.

The programmable flipflop in the LE can be configured for D, T, JK, or SR

operation. The clock, clear, and preset control signals on the flipflop can

be driven by global signals, general-purpose I/O pins, or any internal

logic. For combinatorial functions, the flipflop is bypassed and the output

of the LUT drives the output of the LE.

The LE has two outputs that drive the interconnect; one drives the local

interconnect and the other drives either the row or column FastTrack

Interconnect. The two outputs can be controlled independently. For

example, the LUT can drive one output while the register drives the other

output. This feature, called register packing, can improve LE utilization

because the register and the LUT can be used for unrelated functions.

The FLEX 10K architecture provides two types of dedicated high-speed

data paths that connect adjacent LEs without using local interconnect

paths: carry chains and cascade chains. The carry chain supports high-

speed counters and adders; the cascade chain implements wide-input

functions with minimum delay. Carry and cascade chains connect all LEs

in an LAB and all LABs in the same row. Intensive use of carry and

cascade chains can reduce routing flexibility. Therefore, the use of these

chains should be limited to speed-critical portions of a design.

The carry chain provides a very fast (as low as 0.2 ns) carry-forward

function between LEs. The carry-in signal from a lower-order bit drives

forward into the higher-order bit via the carry chain, and feeds into both

the LUT and the next portion of the carry chain. This feature allows the

FLEX 10K architecture to implement high-speed counters, adders, and

comparators of arbitrary width efficiently. Carry chain logic can be

created automatically by the Quartus and MAX+PLUS II Compilers

during design processing, or manually by the designer during design

entry. Parameterized functions such as LPM and DesignWare functions

automatically take advantage of carry chains.

Carry chains longer than eight LEs are automatically implemented by

linking LABs together. For enhanced fitting, a long carry chain skips

alternate LABs in a row. A carry chain longer than one LAB skips either

from even-numbered LAB to even-numbered LAB, or from odd-

numbered LAB to odd-numbered LAB. For example, the last LE of the

first LAB in a row carries to the first LE of the third LAB in the row. The

carry chain does not cross the EAB at the middle of the row. For instance,

in the EPF10K50 device, the carry chain stops at the eighteenth LAB and a

new one begins at the nineteenth LAB.

Figure 7 shows how an

-bit full adder can be implemented in

+ 1 LEs

with the carry chain. One portion of the LUT generates the sum of two bits

using the input signals and the carry-in signal; the sum is routed to the

output of the LE. The register can either be bypassed for simple adders or

be used for an accumulator function. The carry chain logic generates the

carry-out signal, which is routed directly to the carry-in signal of the next-

higher-order bit. The final carry-out signal is routed to an LE, where it can

be used as a general-purpose signal.

Cascade Chain

With the cascade chain, the FLEX 10K architecture can implement

functions that have a very wide fan-in. Adjacent LUTs can be used to

compute portions of the function in parallel; the cascade chain serially

connects the intermediate values. The cascade chain can use a logical

AND

or logical OR (via De Morgan’s inversion) to connect the outputs of

adjacent LEs. Each additional LE provides four more inputs to the

effective width of a function, with a delay as low as 0.7 ns per LE. Cascade

chain logic can be created automatically by the MAX+PLUS II Compiler

during design processing, or manually by the designer during design

entry.

Cascade chains longer than eight bits are implemented automatically by

linking several LABs together. For easier routing, a long cascade chain

skips every other LAB in a row. A cascade chain longer than one LAB

skips either from even-numbered LAB to even-numbered LAB, or from

odd-numbered LAB to odd-numbered LAB (e.g., the last LE of the first

LAB in a row cascades to the first LE of the third LAB). The cascade chain

does not cross the center of the row (e.g., in the EPF10K50 device, the

cascade chain stops at the eighteenth LAB and a new one begins at the

nineteenth LAB). This break is due to the EAB’s placement in the middle

of the row.

Figure 8 shows how the cascade function can connect adjacent LEs to form

functions with a wide fan-in. These examples show functions of 4n

variables implemented with n LEs. The LE delay is as low as 1.6 ns; the

cascade chain delay is as low as 0.7 ns. With the cascade chain, 3.7 ns is

needed to decode a 16-bit address.

LE Operating Modes

The FLEX 10K LE can operate in the following four modes:

■Normal mode

■Arithmetic mode

■Up/down counter mode

■Clearable counter mode

Each of these modes uses LE resources differently. In each mode, seven

available inputs to the LE—the four data inputs from the LAB local

interconnect, the feedback from the programmable register, and the

carry-in and cascade-in from the previous LE—are directed to different

destinations to implement the desired logic function. Three inputs to the

LE provide clock, clear, and preset control for the register. Quartus and

MAX+PLUS II software packages, in conjunction with parameterized

functions such as LPM and DesignWare functions, automatically chooses

the appropriate mode for common functions such as counters, adders,

and multipliers. If required, the designer can also create special-purpose

functions which use a specific LE operating mode for optimal

performance.

The architecture provides a synchronous clock enable to the register in all

four modes. Quartus and MAX+PLUS II software packages can set DATA1

to enable the register synchronously, providing easy implementation of

fully synchronous designs.

Figure 9 shows the LE operating modes.

Normal Mode

The normal mode is suitable for general logic applications and wide

decoding functions that can take advantage of a cascade chain. In normal

mode, four data inputs from the LAB local interconnect and the carry-in

are inputs to a 4-input LUT. The MAX+PLUS II Compiler automatically

selects the carry-in or the DATA3 signal as one of the inputs to the LUT. The

LUT output can be combined with the cascade-in signal to form a cascade

chain through the cascade-out signal. Either the register or the LUT can be

used to drive both the local interconnect and the FastTrack Interconnect at

the same time.

The LUT and the register in the LE can be used independently; this feature

is known as register packing. To support register packing, the LE has two

outputs; one drives the local interconnect and the other drives the

FastTrack Interconnect. The DATA4 signal can drive the register directly,

allowing the LUT to compute a function that is independent of the

registered signal; a 3-input function can be computed in the LUT, and a

fourth independent signal can be registered. Alternatively, a 4-input

function can be generated, and one of the inputs to this function can be

used to drive the register. The register in a packed LE can still use the

clock enable, clear, and preset signals in the LE. In a packed LE, the

local interconnect, or vice versa.

Arithmetic Mode

The arithmetic mode offers two 3-input LUTs that are ideal for

implementing adders, accumulators, and comparators. One LUT

computes a 3-input function, and the other generates a carry output. As

shown in Figure 9 on page 19, the first LUT uses the carry-in signal and

two data inputs from the LAB local interconnect to generate a

combinatorial or registered output. For example, in an adder, this output

is the sum of three signals: a, b, and carry-in. The second LUT uses the

same three signals to generate a carry-out signal, thereby creating a carry

chain. The arithmetic mode also supports simultaneous use of the cascade

chain.

Up/Down Counter Mode

The up/down counter mode offers counter enable, clock enable,

synchronous up/down control, and data loading options. These control

signals are generated by the data inputs from the LAB local interconnect,

the carry-in signal, and output feedback from the programmable register.

Two 3-input LUTs are used: one generates the counter data, and the other

generates the fast carry bit. A 2-to-1 multiplexer provides synchronous

loading. Data can also be loaded asynchronously with the clear and preset

Altera Corporation 21

FLEX 10K Embedded Programmable Logic Family Data Sheet

Clearable Counter Mode

The clearable counter mode is similar to the up/down counter mode, but

supports a synchronous clear instead of the up/down control. The clear

function is substituted for the cascade-in signal in the up/down counter

mode. Two 3-input LUTs are used: one generates the counter data, and

the other generates the fast carry bit. Synchronous loading is provided by

a 2-to-1 multiplexer. The output of this multiplexer is ANDed with a

synchronous clear signal.

Internal Tri-State Emulation

Internal tri-state emulation provides internal tri-stating without the

limitations of a physical tri-state bus. In a physical tri-state bus, the

tri-state buffers’ output enable (OE) signals select which signal drives the

bus. However, if multiple OE signals are active, contending signals can be

driven onto the bus. Conversely, if no OE signals are active, the bus will

float. Internal tri-state emulation resolves contending tri-state buffers to a

low value and floating buses to a high value, thereby eliminating these

problems. The MAX+PLUS II software automatically implements tri-state

bus functionality with a multiplexer.

Clear & Preset Logic Control

Logic for the programmable register’s clear and preset functions is

controlled by the DATA3, LABCTRL1, and LABCTRL2 inputs to the LE. The

clear and preset control structure of the LE asynchronously loads signals

into a register. Either LABCTRL1 or LABCTRL2 can control the

asynchronous clear. Alternatively, the register can be set up so that

LABCTRL1 implements an asynchronous load. The data to be loaded is

driven to DATA3; when LABCTRL1 is asserted, DATA3 is loaded into the

During compilation, the Quartus and MAX+PLUS II Compilers

automatically select the best control signal implementation. Because the

clear and preset functions are active-low, the Compiler automatically

assigns a logic high to an unused clear or preset.

The clear and preset logic is implemented in one of the following six

modes chosen during design entry:

■Asynchronous clear

■Asynchronous preset

■Asynchronous clear and preset

■Asynchronous load with clear

■Asynchronous load with preset

■Asynchronous load without clear or preset

22 Altera Corporation

FLEX 10K Embedded Programmable Logic Family Data Sheet

In addition to the six clear and preset modes, FLEX 10K devices provide a

chip-wide reset pin that can reset all registers in the device. Use of this

feature is set during design entry. In any of the clear and preset modes, the

chip-wide reset overrides all other signals. Registers with asynchronous

presets may be preset when the chip-wide reset is asserted. Inversion can

be used to implement the asynchronous preset. Figure 10 shows examples

of how to enter a section of a design for the desired functionality.

Asynchronous Clear

The flipflop can be cleared by either LABCTRL1 or LABCTRL2. In this mode,

the preset signal is tied to VCC to deactivate it.

Asynchronous Preset

An asynchronous preset is implemented as either an asynchronous load,

or with an asynchronous clear. If DATA3 is tied to VCC, asserting LABCTRL1

asynchronously loads a one into the register. Alternatively, the

MAX+PLUS II software can provide preset control by using the clear and

inverting the input and output of the register. Inversion control is

available for the inputs to both LEs and IOEs. Therefore, if a register is

preset by only one of the two LABCTRL signals, the DATA3 input is not

needed and can be used for one of the LE operating modes.

Asynchronous Preset & Clear

When implementing asynchronous clear and preset, LABCTRL1 controls

the preset and LABCTRL2 controls the clear. DATA3 is tied to VCC, therefore,

asserting LABCTRL1 asynchronously loads a one into the register,

effectively presetting the register. Asserting LABCTRL2 clears the register.

Asynchronous Load with Clear

When implementing an asynchronous load in conjunction with the clear,

LABCTRL1 implements the asynchronous load of DATA3 by controlling the

the register clear; LABCTRL2 does not have to feed the preset circuits.

Asynchronous Load with Preset

When implementing an asynchronous load in conjunction with preset, the

MAX+PLUS II software provides preset control by using the clear and

inverting the input and output of the register. Asserting LABCTRL2 presets

the register, while asserting LABCTRL1 loads the register. The

MAX+PLUS II software inverts the signal that drives DATA3 to account for

the inversion of the register’s output.

Asynchronous Load without Preset or Clear

When implementing an asynchronous load without preset or clear,

LABCTRL1 implements the asynchronous load of DATA3 by controlling the

FastTrack Interconnect

In the FLEX 10K architecture, connections between LEs and device I/O

pins are provided by the FastTrack Interconnect, which is a series of

continuous horizontal and vertical routing channels that traverse the

device. This global routing structure provides predictable performance,

even in complex designs. In contrast, the segmented routing in FPGAs

requires switch matrices to connect a variable number of routing paths,

increasing the delays between logic resources and reducing performance.

The FastTrack Interconnect consists of row and column interconnect

channels that span the entire device. Each row of LABs is served by a

dedicated row interconnect. The row interconnect can drive I/O pins and

feed other LABs in the device. The column interconnect routes signals

between rows and can drive I/O pins.

A row channel can be driven by an LE or by one of three column channels.

These four signals feed dual 4-to-1 multiplexers that connect to two

specific row channels. These multiplexers, which are connected to each

LE, allow column channels to drive row channels even when all eight LEs

in an LAB drive the row interconnect.

Each column of LABs is served by a dedicated column interconnect. The

column interconnect can then drive I/O pins or another row’s

interconnect to route the signals to other LABs in the device. A signal from

the column interconnect, which can be either the output of an LE or an

input from an I/O pin, must be routed to the row interconnect before it

can enter an LAB or EAB. Each row channel that is driven by an IOE or

EAB can drive one specific column channel.

Access to row and column channels can be switched between LEs in

adjacent pairs of LABs. For example, an LE in one LAB can drive the row

and column channels normally driven by a particular LE in the adjacent

LAB in the same row, and vice versa. This routing flexibility enables

routing resources to be used more efficiently. See Figure 11.

For improved routing, the row interconnect is comprised of a combination

of full-length and half-length channels. The full-length channels connect

to all LABs in a row; the half-length channels connect to the LABs in half

of the row. The EAB can be driven by the half-length channels in the left

half of the row and by the full-length channels. The EAB drives out to the

full-length channels. In addition to providing a predictable, row-wide

interconnect, this architecture provides increased routing resources. Two

neighboring LABs can be connected using a half-row channel, thereby

saving the other half of the channel for the other half of the row.

Table 7 summarizes the FastTrack Interconnect resources available in

each FLEX 10K device.

In addition to general-purpose I/O pins, FLEX 10K devices have six

dedicated input pins that provide low-skew signal distribution across the

device. These six inputs can be used for global clock, clear, preset, and

peripheral output enable and clock enable control signals. These signals

are available as control signals for all LABs and IOEs in the device.

The dedicated inputs can also be used as general-purpose data inputs

because they can feed the local interconnect of each LAB in the device.

However, the use of dedicated inputs as data inputs can introduce

additional delay into the control signal network.

An I/O element (IOE) contains a bidirectional I/O buffer and a register

that can be used either as an input register for external data that requires

a fast setup time, or as an output register for data that requires fast clock-

to-output performance. In some cases, using an LE register for an input

can be used as input, output, or bidirectional pins. The Quartus and

MAX+PLUS II Compilers use the programmable inversion option to

invert signals from the row and column interconnect automatically where

appropriate. Figure 13 shows the IOE block diagram.

Each IOE selects the clock, clear, clock enable, and output enable controls

from a network of I/O control signals called the peripheral control bus.

The peripheral control bus uses high-speed drivers to minimize signal

skew across devices; it provides up to 12 peripheral control signals that

can be allocated as follows:

■Up to eight output enable signals

■Up to six clock enable signals

■Up to two clock signals

■Up to two clear signals

If more than six clock enable or eight output enable signals are required,

each IOE on the device can be controlled by clock enable and output

enable signals driven by specific LEs. In addition to the two clock signals

available on the peripheral control bus, each IOE can use one of two

dedicated clock pins. Each peripheral control signal can be driven by any

of the dedicated input pins or the first LE of each LAB in a particular row.

In addition, an LE in a different row can drive a column interconnect,

which causes a row interconnect to drive the peripheral control signal.

The chip-wide reset signal will reset all IOE registers, overriding any

other control signals.

Tables 8 and 9 list the sources for each peripheral control signal, and the

rows that can drive global signals. These tables also show how the output

enable, clock enable, clock, and clear signals share 12 peripheral control

signals.

Signals on the peripheral control bus can also drive the four global signals,

referred to as GLOBAL0 through GLOBAL3 in Tables 8 and 9. The internally

generated signal can drive the global signal, providing the same

low-skew, low-delay characteristics for an internally generated signal as

for a signal driven by an input. This feature is ideal for internally

generated clear or clock signals with high fan-out. When a global signal is

driven by internal logic, the dedicated input pin that drives that global

signal cannot be used. The dedicated input pin should be driven to a

known logic state (such as ground) and not be allowed to float.

When the chip-wide output enable pin is held low, it will tri-state all pins

on the device. This option can be set in the Global Project Device Options

menu. Additionally, the registers in the IOE can be reset by holding the

chip-wide reset pin low.

Row-to-IOE Connections

When an IOE is used as an input signal, it can drive two separate row

channels. The signal is accessible by all LEs within that row. When an IOE

is used as an output, the signal is driven by a multiplexer that selects a

signal from the row channels. Up to eight IOEs connect to each side of

each row channel. See Figure 14.

SameFrame

Pin-Outs

FLEX 10KE devices support the SameFrame pin-out feature for

FineLine BGA packages. The SameFrame pin-out feature is the

arrangement of balls on FineLine BGA packages such that the lower-ball-

count packages form a subset of the higher-ball-count packages.

SameFrame pin-outs provide the flexibility to migrate not only from

device to device within the same package, but also from one package to

another. A given printed circuit board (PCB) layout can support multiple

device density/package combinations. For example, a single board layout

can support a range of devices from an EPF10K30E device in a 256-pin

FineLine BGA package to an EPF10K200S device in a 672-pin

FineLine BGA package.

The Quartus and MAX+PLUS II software provides support to design

PCBs with SameFrame pin-out devices. Devices can be defined for present

and future use. The MAX+PLUS II software generates pin-outs describing

ClockLock &

ClockBoost

Features

To support high-speed designs, selected FLEX 10K devices offer optional

ClockLock and ClockBoost circuitry containing a phase-locked loop (PLL)

that is used to increase design speed and reduce resource usage. The

ClockLock circuitry uses a synchronizing PLL that reduces the clock delay

and skew within a device. This reduction minimizes clock-to-output and

setup times while maintaining zero hold times. The ClockBoost circuitry,

which provides a clock multiplier, allows the designer to enhance device

area efficiency by sharing resources within the device. The ClockBoost

feature allows the designer to distribute a low-speed clock and multiply

that clock on-device. Combined, the ClockLock and ClockBoost features

provide significant improvements in system performance and

bandwidth.

The ClockLock and ClockBoost features in FLEX 10K devices are enabled

through the MAX+PLUS II software. External devices are not required to

use these features. The output of the ClockLock and ClockBoost circuits is

not available at any of the device pins.

The ClockLock and ClockBoost circuitry locks onto the rising edge of the

incoming clock. The circuit output can only drive the clock inputs of

registers; the generated clock cannot be gated or inverted.

The dedicated clock pin (GCLK1) supplies the clock to the ClockLock and

ClockBoost circuitry. When the dedicated clock pin is driving the

ClockLock or ClockBoost circuitry, it cannot drive elsewhere in the

device.

In designs that require both a multiplied and non-multiplied clock, the

clock trace on the board can be connected to GCLK1. With the

MAX+PLUS II software, GCLK1 can feed both the ClockLock and

ClockBoost circuitry in the FLEX 10K device. However, when both

circuits are used, the other clock pin (GCLK0) cannot be used. Figure 17

shows a block diagram of how to enable both the ClockLock and

ClockBoost circuits in the MAX+PLUS II software. The example shown is

a schematic, but a similar approach applies for designs created in AHDL,

VHDL, and Verilog HDL. When the ClockLock and ClockBoost circuits

are used simultaneously, the input frequency parameter must be the same

for both circuits. In Figure 17, the input frequency must meet the

requirements specified when the ClockBoost multiplication factor is two.

Altera Corporation 37

FLEX 10K Embedded Programmable Logic Family Data Sheet

Figure 17. Enabling ClockLock & ClockBoost in the Same Design

To use both the ClockLock and ClockBoost circuits in the same design,

designers must use Revision C EPF10K100GC503-3DX devices and

MAX+PLUS II software versions 7.2 or higher. The die revision is

indicated by the third digit of the nine-digit code on the top side of the

device.

which is available from Altera Literature Services.

Output

Conﬁguration

This section discusses the peripheral component interconnect (PCI)

pull-up clamping diode option, slew-rate control, open-drain output

option, MultiVolt I/O interface, and power sequencing for FLEX 10K

devices. The PCI pull-up clamping diode, slew-rate control, and

open-drain output options are controlled pin-by-pin via MAX+PLUS II

logic options. The MultiVolt I/O interface is controlled by connecting

VCCIO to a different voltage than VCCINT. Its effect can be simulated in the

MAX+PLUS II software via the Global Project Device Options dialog

box (Assign menu).

PCI Clamping Diodes

The EPF10K10A and EPF10K30A devices have a pull-up clamping diode

on every I/O, dedicated input, and dedicated clock pin. PCI clamping

diodes clamp the transient overshoot caused by reflected waves to the

VCCIO value and are required for 3.3-V PCI compliance. Clamping diodes

can also be used to limit overshoot in other systems.

38 Altera Corporation

FLEX 10K Embedded Programmable Logic Family Data Sheet

Clamping diodes are controlled on a pin-by-pin basis via a logic option in

the MAX+PLUS II software. When VCCIO is 3.3 V, a pin that has the

clamping diode turned on can be driven by a 2.5-V or 3.3-V signal, but not

a 5.0-V signal. When VCCIO is 2.5 V, a pin that has the clamping diode

turned on can be driven by a 2.5-V signal, but not a 3.3-V or 5.0-V signal.

However, a clamping diode can be turned on for a subset of pins, which

allows devices to bridge between a 3.3-V PCI bus and a 5.0-V device.

Slew-Rate Control

The output buffer in each IOE has an adjustable output slew rate that can

be configured for low-noise or high-speed performance. A slower slew

rate reduces system noise and adds a maximum delay of approximately

2.9 ns. The fast slew rate should be used for speed-critical outputs in

systems that are adequately protected against noise. Designers can specify

the slew rate on a pin-by-pin basis during design entry or assign a default

slew rate to all pins on a device-wide basis. The slow slew rate setting

affects only the falling edge of the output.

Open-Drain Output Option

FLEX 10K devices provide an optional open-drain (electrically equivalent

to an open-collector) output for each I/O pin. This open-drain output

enables the device to provide system-level control signals (e.g., interrupt

and write enable signals) that can be asserted by any of several devices. It

can also provide an additional wired-OR plane. Additionally, the

MAX+PLUS II software can convert tri-state buffers with grounded data

inputs to open-drain pins automatically.

Open-drain output pins on FLEX 10K devices (with a pull-up resistor to

the 5.0-V supply) can drive 5.0-V CMOS input pins that require a VIH of

3.5 V. When the open-drain pin is active, it will drive low. When the pin

is inactive, the trace will be pulled up to 5.0 V by the resistor. The open-

drain pin will only drive low or tri-state; it will never drive high. The rise

time is dependent on the value of the pull-up resistor and load

impedance. The IOL current specification should be considered when

selecting a pull-up resistor.

Output pins on 5.0-V FLEX 10K devices with VCCIO = 3.3 V or 5.0 V (with

a pull-up resistor to the 5.0-V supply) can also drive 5.0-V CMOS input

pins. In this case, the pull-up transistor will turn off when the pin voltage

exceeds 3.3 V. Therefore, the pin does not have to be open-drain.

Altera Corporation 39

FLEX 10K Embedded Programmable Logic Family Data Sheet

MultiVolt I/O Interface

The FLEX 10K device architecture supports the MultiVolt I/O interface

feature, which allows FLEX 10K devices to interface with systems of

differing supply voltages. These devices have one set of VCC pins for

internal operation and input buffers (VCCINT) and another set for I/O

output drivers (VCCIO).

Table 12 describes the FLEX 10K device supply voltages and MultiVolt

I/O support levels.

Note

(1) The 240 pin QFP pagckages do not support the MultiVolt I/O feature so there are

no VCCIO pins.

Power Sequencing & Hot-Socketing

Because FLEX 10K devices can be used in a multi-voltage environment,

they have been designed specifically to tolerate any possible power-up

sequence. The VCCIO and VCCINT power planes can be powered in any

order.

Signals can be driven into FLEX 10KA devices before and during power

up without damaging the device. Additionally, FLEX 10KA devices do

not drive out during power up. Once operating conditions are reached,

FLEX 10KA devices operate as specified by the user.

IEEE Std.

Boundary-Scan

Support

All FLEX 10K devices provide JTAG BST circuitry that complies with the

IEEE Std. 1149.1-1990 specification. All FLEX 10K devices can also be

configured using the JTAG pins through the BitBlaster serial download

cable, ByteBlaster parallel port download cable, or ByteBlasterMV parallel

port download cable, or via hardware that uses the JamTM programming

and test language. JTAG BST can be performed before or after

configuration, but not during configuration. FLEX 10K devices support

the JTAG instructions shown in Table 13.

The instruction register length of FLEX 10K devices is 10 bits. The

USERCODE register length in FLEX 10K devices is 32 bits; 7 bits are

determined by the user, and 25 bits are predetermined. Tables 14 and 15

show the boundary-scan register length and device IDCODE information

for FLEX 10K devices.

Table 13. FLEX 10K JTAG Instructions

JTAG Instruction Description

SAMPLE/PRELOAD Allows a snapshot of signals at the device pins to be captured and examined during

normal device operation, and permits an initial data pattern output at the device pins.

EXTEST Allows the external circuitry and board-level interconnections to be tested by forcing a

test pattern at the output pins and capturing test results at the input pins.

BYPASS Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST

data to pass synchronously through a selected device to adjacent devices during normal

device operation.

USERCODE Selects the user electronic signature (USERCODE) register and places it between the

TDI and TDO pins, allowing the USERCODE to be serially shifted out of TDO.

IDCODE Selects the IDCODE register and places it between TDI and TDO, allowing the IDCODE

to be serially shifted out of TDO.

ICR Instructions These instructions are used when configuring a FLEX 10K device via JTAG ports with a

BitBlaster, ByteBlaster, or ByteBlasterMV download cable, or using a Jam File (.jam) or

Notes to tables:

(1) See the Operating Requirements for Altera Devices Data Sheet.

(2) Minimum DC voltage input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to

5.75 V for input currents less than 100 mA and periods shorter than 20 ns. FLEX 10KA devices can withstand a

11 V pulse for 11ns.

(3) Numbers in parentheses are for industrial-temperature-range devices.

(4) Maximum VCC rise time is 100 ms, and VCC must rise monotonically.

(5) FLEX 10KA device inputs may be driven before VCCINT and VCCIO are powered.

(6) Typical values are for TA = 25° C and VCC = 3.3 V.

(7) These values are specified under Table 27 on page 49.

(8) The IOH parameter refers to high-level TTL, PCI, or CMOS output current.

(9) The IOL parameter refers to low-level TTL, PCI, or CMOS output current. This parameter applies to open-drain pins

as well as output pins.

(10) This parameter applies to all -1 speed grade commercial temperature devices and all -2 speed grade

industrial-temperature devices.

EPF10K30A, EPF10K100A, and EPF10K250A devices with 3.3-V and 2.5-V

VCCIO. The output driver is compliant with the 3.3-V PCI Local Bus

Specification, Revision 2.2 (with 3.3-V VCCIO). Moreover, device analysis

shows that the EPF10K10A, EPF10K30A, and EPF 10K100A devices can

Timing Model The continuous, high-performance FastTrack Interconnect routing

resources ensure predictable performance and accurate simulation and

timing analysis. This predictable performance contrasts with that of

FPGAs, which use a segmented connection scheme and therefore have

unpredictable performance.

Device performance can be estimated by following the signal path from a

source, through the interconnect, to the destination. For example, the

registered performance between two LEs on the same row can be

calculated by adding the following parameters:

■LE register clock-to-output delay (tCO)

■Interconnect delay (tSAMEROW)

■LE look-up table delay (tLUT)

■LE register setup time (tSU)

The routing delay depends on the placement of the source and destination

LEs. A more complex registered path may involve multiple combinatorial

LEs between the source and destination LEs.

Timing simulation and delay prediction are available with the

MAX+PLUS II Simulator and Timing Analyzer, or with industry-

standard EDA tools. The Simulator offers both pre-synthesis functional

simulation to evaluate logic design accuracy and post-synthesis timing

simulation with 0.1-ns resolution. The Timing Analyzer provides point-

to-point timing delay information, setup and hold time analysis, and

device-wide performance analysis.

Tables 32 through 36 describe the FLEX 10K device internal timing

parameters. These internal timing parameters are expressed as worst-case

values. Using hand calculations, these parameters can be used to estimate

design performance. However, before committing designs to silicon,

actual worst-case performance should be modeled using timing

Notes to tables:

(1) Microparameters are timing delays contributed by individual architectural elements. These parameters cannot be

measured explicitly.

(2) Operating conditions: VCCIO = 5.0 V ± 5% for commercial use in FLEX 10K devices.

VCCIO = 5.0 V ± 10% for industrial use in FLEX 10K devices.

VCCIO = 3.3 V ± 10% for commercial or industrial use in FLEX 10KA devices.

(3) Operating conditions: VCCIO = 3.3 V ± 10% for commercial or industrial use in FLEX 10K devices.

VCCIO = 2.5 V ± 0.2 V for commercial or industrial use in FLEX 10KA devices.

(4) Operating conditions: VCCIO = 2.5 V, 3.3 V, or 5.0 V.

(5) Because the RAM in the EAB is self-timed, this parameter can be ignored when the WE signal is registered.

(6) EAB macroparameters are internal parameters that can simplify predicting the behavior of an EAB at its boundary;

these parameters are calculated by summing selected microparameters.

(7) These parameters are worst-case values for typical applications. Post-compilation timing simulation and timing

analysis are required to determine actual worst-case performance.

(8) External reference timing parameters are factory-tested, worst-case values specified by Altera. A representative

subset of signal paths is tested to approximate typical device applications.

(9) Contact Altera Applications for test circuit specifications and test conditions.

(10) These timing parameters are sample-tested only.

ClockLock &

ClockBoost

Timing

Parameters

For the ClockLock and ClockBoost circuitry to function properly, the

incoming clock must meet certain requirements. If these specifications are

not met, the circuitry may not lock onto the incoming clock, which

generates an erroneous clock within the device. The clock generated by

the ClockLock and ClockBoost circuitry must also meet certain

specifications. If the incoming clock meets these requirements during

configuration, the ClockLock and ClockBoost circuitry will lock onto the

clock during configuration. The circuit will be ready for use immediately

after configuration. Figure 31 illustrates the incoming and generated clock

specifications.

Figure 31. Speciﬁcations for the Incoming & Generated Clocks

The tI parameter refers to the nominal input clock period; the tO parameter refers to the

nominal output clock period.

Table 114 summarizes the ClockLock and ClockBoost parameters.

Notes:

(1) To implement the ClockLock and ClockBoost circuitry with the MAX+PLUS II software, designers must specify the

input frequency. The MAX+PLUS II software tunes the PLL in the ClockLock and ClockBoost circuitry to this

frequency. The fCLKDEV parameter specifies how much the incoming clock can differ from the specified frequency

during device operation. Simulation does not reflect this parameter.

(2) During device configuration, the ClockLock and ClockBoost circuitry is configured before the rest of the device. If

the incoming clock is supplied during configuration, the ClockLock and ClockBoost circuitry locks during

configuration, because the tLOCK value is less than the time required for configuration.

(3) The tJITTER specification is measured under long-term observation.

Power

Consumption

The supply power (P) for FLEX 10K devices can be calculated with the

following equation:

P = PINT + PIO = (ICCSTANDBY + ICCACTIVE) × VCC + PIO

Typical ICCSTANDBY values are shown as ICC0 in the FLEX 10K device DC

operating conditions tables on pages 44, 47, and 50 of this data sheet. The

ICCACTIVE value depends on the switching frequency and the application

logic. This value is calculated based on the amount of current that each LE

typically consumes. The PIO value, which depends on the device output

load characteristics and switching frequency, can be calculated using the

guidelines given in Application Note 74 (Evaluating Power for Altera

Devices).

FLEX 10K Embedded Programmable Logic Family Data Sheet

1Compared to the rest of the device, the embedded array

consumes a negligible amount of power. Therefore, the

embedded array can be ignored when calculating supply

current.

The ICCACTIVE value is calculated with the following equation:

ICCACTIVE = K × fMAX × N × togLC ×

The parameters in this equation are shown below:

fMAX = Maximum operating frequency in MHz

N= Total number of logic cells used in the device

togLC = Average percent of logic cells toggling at each clock

(typically 12.5%)

K= Constant, shown in Tables 115 and 116

This calculation provides an ICC estimate based on typical conditions with

no output load. The actual ICC should be verified during operation

because this measurement is sensitive to the actual pattern in the device

and the environmental operating conditions.

To better reflect actual designs, the power model (and the constant K in

the power calculation equations) for continuous interconnect FLEX

devices assumes that logic cells drive FastTrack Interconnect channels. In

contrast, the power model of segmented FPGAs assumes that all logic

cells drive only one short interconnect segment. This assumption may

lead to inaccurate results, compared to measured power consumption for

an actual design in a segmented interconnect FPGA.

Figure 32 shows the relationship between the current and operating

frequency of FLEX 10K devices.

Conﬁguration &

Operation

The FLEX 10K architecture supports several configuration schemes. This

section summarizes the device operating modes and available device

configuration schemes.

fSee Application Note 59 (Configuring FLEX 10K Devices) for detailed

descriptions of device configuration options, device configuration pins,

and for information on configuring FLEX 10K devices, including sample

schematics, timing diagrams, and configuration parameters.

Operating Modes

The FLEX 10K architecture uses SRAM configuration elements that

require configuration data to be loaded every time the circuit powers up.

The process of physically loading the SRAM data into the device is called

configuration. During initialization, which occurs immediately after

configuration, the device resets registers, enables I/O pins, and begins to

operate as a logic device. The I/O pins are tri-stated during power-up,

and before and during configuration. Together, the configuration and

initialization processes are called command mode; normal device operation

is called user mode.

SRAM configuration elements allow FLEX 10K devices to be reconfigured

in-circuit by loading new configuration data into the device. Real-time

reconfiguration is performed by forcing the device into command mode

with a device pin, loading different configuration data, reinitializing the

device, and resuming user-mode operation.

FLEX 10K Embedded Programmable Logic Family Data Sheet

The entire reconfiguration process may be completed in less than 320 ms

using an EPF10K250A device with a DCLK frequency of 10 MHz. This

process can be used to reconfigure an entire system dynamically. In-field

upgrades can be performed by distributing new configuration files.

Programming Files

Despite being function- and pin-compatible, FLEX 10KA and FLEX 10KE

devices are not programming- or configuration-file compatible with

FLEX 10K devices. A design should be recompiled before it is transferred

from a FLEX 10K device to an equivalent FLEX 10KA or FLEX 10KE

device. This recompilation should be performed to create a new

programming or configuration file and to check design timing on the

faster FLEX 10KA or FLEX 10KE device. The programming or

configuration files for EPF10K50 devices can program or configure an

EPF10K50V device. However, Altera recommends recompiling a design

for the EPF10K50V device when transferring it from the EPF10K50 device.

Conﬁguration Schemes

The configuration data for a FLEX 10K device can be loaded with one of

five configuration schemes (see Table 117), chosen on the basis of the

target application. An EPC2, EPC1, or EPC1441 configuration device,

intelligent controller, or the JTAG port can be used to control the

configuration of a FLEX 10K device, allowing automatic configuration on

system power-up.

Multiple FLEX 10K devices can be configured in any of the five

configuration schemes by connecting the configuration enable (nCE) and

configuration enable output (nCEO) pins on each device.

Notes to tables:

(1) All pins that are not listed are user I/O pins.

(2) This pin is a dedicated pin; it is not available as a user I/O pin.

(3) This pin can be used as a user I/O pin if it is not used for its device-wide or configuration function.

(4) This pin can be used as a user I/O pin after configuration.

(5) This pin is tri-stated in user mode.

(6) The optional JTAG pin

TRST

is not used in the 100-pin or 144-pin TQFP package.

(7) To maintain pin compatibility when transferring to the EPF10K10 or EPF10K10A device from any other device in

the 208-pin PQFP or 256-pin FineLine BGA package, do not use these pins as user I/O pins.

(8) The user I/O pin count includes dedicated input pins, dedicated clock pins, and all I/O pins.

(9) To maintain pin compatibility when transferring to the EPF10K30 device from any other device in the 356-pin BGA

or 484-pin FineLine BGA package, do not use these pins as user I/O pins.

(10) To maintain pin compatibility when transferring to the EPF10K50V device from any other device in the 484-pin

FineLine BGA package, do not use these pins as user I/O pins.

(11) To maintain pin compatibility when transferring from the EPF10K100 to the EPF10K70 in the 503-pin PGA package,

do not use these pins as user I/O pins.

(12) This pin shows the status of the ClockLock and ClockBoost circuitry. When the ClockLock and ClockBoost circuitry

are locked to the incoming clock and generate an internal clock,

LOCK

is driven high.

LOCK

remains high if a periodic

clock stops clocking. The

LOCK

function is optional; if the

LOCK

output is not used, this pin is a user I/O pin.

(13) This pin drives the ClockLock and ClockBoost circuitry.

(14) This pin is the power or ground for the ClockLock and ClockBoost circuitry. To ensure noise resistance, the power

and ground supply to the ClockLock and ClockBoost circuitry should be isolated from the power and ground to the

rest of the device.

(15) To maintain pin compatibility when transferring to the EPF10K100A device from another device in the 600-pin BGA

package, do not use these pins as user I/O pins.

(16) The 240-pin QFP packages do not support the MultiVolt I/O feature so there are no V

CCIO

pins.
