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 Device 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 EPC1, EPC2, EPC16, 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
TM
serial download cable or ByteBlasterMV
TM
parallel port
download cable. 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 116 (Configuring APEX 20K, FLEX 10K & FLEX 6000
Devices)
FLEX 10K devices are supported by Altera development systems; single,
integrated packages that offer schematic, text (including AHDL), and
waveform design entry, compilation and logic synthesis, full simulation
and worst-case timing analysis, and device configuration. The Altera
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 Altera software works easily with common gate array EDA tools for
synthesis and simulation. For example, the Altera software can generate
Verilog HDL files for simulation with tools such as Cadence Verilog-XL.
Additionally, the Altera 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 Altera development systems include DesignWare
functions that are optimized for the FLEX 10K architecture.
The Altera development systems run on Windows-based PCs and Sun
SPARCstation, and HP 9000 Series 700/800 workstations.

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 Device 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 Device 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 Device 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 (
WE
) signal, while ensuring that its data
and address signals meet setup and hold time specifications relative to the
WE
signal. In contrast, the EAB’s synchronous RAM generates its own
WE
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

Altera Corporation 11
FLEX 10K Embedded Programmable Logic Device 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 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
WE
inputs. The global signals and the EAB local interconnect can drive
the
WE
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
WE
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.

FLEX 10K Embedded Programmable Logic Device Family Data Sheet
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.
Carry Chain
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 Compiler 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
n
-bit full adder can be implemented in
n
+ 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 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 4
n
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. The Altera
software, 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. The Altera software 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 four-input LUT. The 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 three-input function can be computed in the LUT, and
a fourth independent signal can be registered. Alternatively, a four-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
register can drive the FastTrack Interconnect while the LUT drives the
local interconnect, or vice versa.
Arithmetic Mode
The arithmetic mode offers 2 three-input LUTs that are ideal for
implementing adders, accumulators, and comparators. One LUT
computes a three-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.
Altera Corporation 21
FLEX 10K Embedded Programmable Logic Device Family Data Sheet
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.
The Up/down counter mode uses 2 three-input LUTs: 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 register control signals, without
using the LUT resources.
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. Clearable counter mode uses 2 three-input LUTs: 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 Altera 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
register.
22 Altera Corporation
FLEX 10K Embedded Programmable Logic Device Family Data Sheet
During compilation, the Compiler automatically selects 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
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 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 Altera
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
register preset and clear. LABCTRL2 implements the clear by controlling
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
Altera 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 Altera 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
register preset and clear.
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.
Altera Corporation 25
FLEX 10K Embedded Programmable Logic Device Family Data Sheet
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.

I/O Element
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
register will result in a faster setup time than using an IOE register. IOEs
can be used as input, output, or bidirectional pins. For bidirectional
registered I/O implementation, the output register should be in the IOE
and, the data input and output enable register should be LE registers
placed adjacent to the bidirectional pin. The Compiler uses the
programmable inversion option to invert signals from the row and
column interconnect automatically where appropriate. Figure 13 shows
the bidirectional I/O registers.

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.

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 EPF10K10A device in a 256-pin
FineLine BGA package to an EPF10K100A device in a 484-pin
FineLine BGA package.
The Altera software provides support to design PCBs with SameFrame
pin-out devices. Devices can be defined for present and future use. The
Altera software generates pin-outs describing how to lay out a board to
take advantage of this migration (see Figure 16).

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 Altera 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 Altera
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 Altera
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.

FLEX 10K Embedded Programmable Logic Device 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.
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 Altera 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 Altera
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.
Clamping diodes are controlled on a pin-by-pin basis via a logic option in
the Altera 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 Altera
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.
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).
40 Altera Corporation
FLEX 10K Embedded Programmable Logic Device Family Data Sheet
Table 12 describes the FLEX 10K device supply voltages and MultiVolt
I/O support levels.
Note
(1) 240-pin QFP packages do not support the MultiVolt I/O features, so they do not have separate 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 supplies 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.

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, 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.

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.

Power supply transients can affect AC
measurements. Simultaneous transitions of
multiple outputs should be avoided for
accurate measurement. Threshold tests must
not be performed under AC conditions.
Large-amplitude, fast-ground-current
transients normally occur as the device
outputs discharge the load capacitances.
When these transients flow through the
parasitic inductance between the device
ground pin and the test system ground,
significant reductions in observable noise
immunity can result. Numbers without

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.

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.
Figures 29 and 30 show the asynchronous and synchronous timing
waveforms, respectively, for the EAB macroparameters in Table 34.

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 113 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 46, 49, and 52 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).
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:
fCLKDEV1 Input deviation from user specification in MAX+PLUS II (ClockBoost clock
multiplication factor equals 1) (1) ±1 MHz
fCLKDEV2 Input deviation from user specification in MAX+PLUS II (ClockBoost clock
multiplication factor equals 2) (1) ±0.5 MHz
tINCLKSTB Input clock stability (measured between adjacent clocks) 100 ps
tLOCK Time required for ClockLock or ClockBoost to acquire lock (2) 10 µs
tJITTER Jitter on ClockLock or ClockBoost-generated clock (3) 1ns

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.

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 116 (Configuring APEX 20K, FLEX 10K & FLEX 6000
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. Before configuration, as VCC rises, the device initiates a
Power-On Reset (POR). This POR event clears the device and prepares it
for configuration. The FLEX 10K POR time does not exceed 50 µs.
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.

FLEX 10K Embedded Programmable Logic Device Family Data Sheet
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.
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.
1Refer to the configuration device data sheet to obtain the POR
delay when using a configuration device method.
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 116), chosen on the basis of the
target application. An EPC1, EPC2, EPC16, 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.
126 Altera Corporation
FLEX 10K Embedded Programmable Logic Device Family Data Sheet
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.
