Description

Actel’s ACT 3 Accelerator Series of FPGAs offers the

industry’s fastest high-capacity programmable logic device.

ACT 3 FPGAs offer a high perfomance, PCI compliant

programmable solution capable of 250 MHz on-chip

performance and 7.5 nanosecond clock-to-output, with

capacities spanning from 1,500 to 10,000 gate array

equivalent gates. For further information regarding PCI

compliance of ACT 3 devices, see “Accelerator Series

FPGAs—ACT 3 PCI Compliant Family.”

The ACT 3 family builds on the proven two-module

architecture consisting of combinatorial and sequential logic

modules used in Actel’s 3200DX and 1200XL families. In

addition, the ACT 3 I/O modules contain registers which

deliver 7.5 nanosecond clock-to-out times. The devices

contain four clock distribution networks, including dedicated

array and I/O clocks, supporting very fast synchronous and

asynchronous designs. In addition, routed clocks can be used

to drive high fanout signals such as flip-flop resets and output

enables.

The ACT 3 family is supported by Actel’s Designer Series

Development System which offers automatic placement and

routing (with automatic or fixed pin assignments), static

timing anlaysis, user programming, and debug and diagnostic

probe capabilities. The Designer Series is supported on the

following platforms: 486/Pentium class PC’s, Sun

‚ and HP

‚

workstations. The software provides CAE interfaces to

Cadence, Mentor Graphics

, OrCAD

™

and Viewlogic

‚

design environments. Additional platforms are supported

through Actel’s Industry Alliance Program, including DATA

I/O (ABEL FPGA) and MINC.

3 Family

Architecture

This section of the data sheet is meant to familiarize the user

with the architecture of the ACT 3 family of FPGA devices. A

generic description of the family will be presented first,

followed by a detailed description of the logic blocks, the

routing structure, the antifuses, and the special function

circuits. The on-chip circuitry required to program the

devices is not covered.

Topology

The ACT 3 family architecture is composed of six key

elements: Logic modules, I/O modules, I/O Pad Drivers,

Routing Tracks, Clock Networks, and Programming and Test

Circuits. The basic structure is similar for all devices in the

family, differing only in the number of rows, columns, and

I/Os. The array itself consists of alternating rows of modules

and channels. The logic modules and channels are in the

center of the array; the I/O modules are located along the

array periphery. A simplified floor plan is depicted in

Figure 1.

Logic Modules

ACT 3 logic modules are enhanced versions of the 1200XL

family logic modules. As in the 1200XL family, there are two

types of modules: C-modules and S-modules. The C-module is

functionally equivalent to the 1200XL C-module and

implements high fanin combinatorial macros, such as 5-input

AND, 5-input OR, and so on. It is available for use as the CM8

hard macro. The S-module is designed to implement

high-speed sequential functions within a single module.

S-modules consist of a full C-module driving a flip-flop, which

allows an additional level of logic to be implemented without

additional propagation delay. It is available for use as the

DFM8A/B and DLM8A/B hard macros. C-modules and

S-modules are arranged in pairs called module-pairs.

Module-pairs are arranged in alternating patterns and make

up the bulk of the array. This arrangement allows the

placement software to support two-module macros of four

types (CC, CS, SC, and SS). The C-module implements the

following function:

Y = !S1 * !S0 * D00 + !S1 * S0 * D01 + S1 * !S0 * D10 + S1 * S0

* D11

where: S0 = A0 * B0 and S1 = A1 + B1

The S-module contains a full implementation of the C-module

plus a clearable sequential element that can either

implement a latch or flip-flop function. The S-module can

therefore implement any function implemented by the

C-module. This allows complex combinatorial-sequential

functions to be implemented with no delay penalty. The

Designer Series Development System will automatically

combine any C-module macro driving an S-module macro into

the S-module, thereby freeing up a logic module and

eliminating a module delay.

The clear input CLR is accessible from the routing channel.

In addition, the clock input may be connected to one of three

clock networks: CLKA, CLKB, or HCLK. The C-module and

S-module functional descriptions are shown in Figures 2

and 3. The clock selection is determined by a multiplexor

select at the clock input to the S-module.

I/Os

I/O Modules

I/O modules provide an interface between the array and the

I/O Pad Drivers. I/O modules are located in the array and

access the routing channels in a similar fashion to logic

modules. The I/O module schematic is shown in Figure 4. The

signals DataIn and DataOut connect to the I/O pad driver.

Each I/O module contains two D-type flip-flops. Each flip-flop

is connected to the dedicated I/O clock (IOCLK). Each

flip-flop can be bypassed by nonsequential I/Os. In addition,

each flip-flop contains a data enable input that can be

accessed from the routing channels (ODE and IDE). The

asynchronous preset/clear input is driven by the dedicated

preset/clear network (IOPCL). Either preset or clear can be

selected individually on an I/O module by I/O module basis.

The I/O module output Y is used to bring Pad signals into the

array or to feed the output register back into the array. This

allows the output register to be used in high-speed state

machine applications. Side I/O modules have a dedicated

output segment for Y extending into the routing channels

above and below (similar to logic modules). Top/Bottom I/O

modules have no dedicated output segment. Signals coming

into the chip from the top or bottom are routed using F-fuses

and LVTs (F-fuses and LVTs are explained in detail in the

routing section).

I/O Pad Drivers

All pad drivers are capable of being tristate. Each buffer

connects to an associated I/O module with four signals: OE

(Output Enable), IE (Input Enable), DataOut, and DataIn.

Certain special signals used only during programming and

test also connect to the pad drivers: OUTEN (global output

enable), INEN (global input enable), and SLEW (individual

slew selection). See Figure 5.

Special I/Os

The special I/Os are of two types: temporary and permanent.

Temporary special I/Os are used during programming and

testing. They function as normal I/Os when the MODE pin is

inactive. Permanent special I/Os are user programmed as

either normal I/Os or special I/Os. Their function does not

change once the device has been programmed. The

permanent special I/Os consist of the array clock input

buffers (CLKA and CLKB), the hard-wired array clock input

buffer (HCLK), the hard-wired I/O clock input buffer

(IOCLK), and the hard-wired I/O register preset/clear input

buffer (IOPCL). Their function is determined by the I/O

macros selected.

Clock Networks

The ACT 3 architecture contains four clock networks: two

high-performance dedicated clock networks and two general

purpose routed networks. The high-performance networks

function up to 200 MHz, while the general purpose routed

networks function up to 150 MHz.

Dedicated Clocks

Dedicated clock networks support high performance by

providing sub-nanosecond skew and guaranteed

performance. Dedicated clock networks contain no

programming elements in the path from the I/O Pad Driver to

the input of S-modules or I/O modules. There are two

dedicated clock networks: one for the array registers (HCLK),

and one for the I/O registers (IOCLK). The clock networks

are accessed by special I/Os.

Routed Clocks

The routed clock networks are referred to as CLK0 and CLK1.

Each network is connected to a clock module (CLKMOD)

that selects the source of the clock signal and may be driven

as follows (see Figure 6):

• externally from the CLKA pad

• externally from the CLKB pad

• internally from the CLKINA input

• internally from the CLKINB input

The clock modules are located in the top row of I/O modules.

Clock drivers and a dedicated horizontal clock track are

located in each horizontal routing channel. The function of

the clock module is determined by the selection of clock

macros from the macro library. The macro CLKBUF is used to

connect one of the two external clock pins to a clock network,

and the macro CLKINT is used to connect an internally

generated clock signal to a clock network. Since both clock

networks are identical, the user does not care whether CLK0

or CLK1 is being used. Routed clocks can also be used to drive

high fanout nets like resets, output enables, or data enables.

This saves logic modules and results in performance

increases in some cases.

Routing Structure

The ACT 3 architecture uses vertical and horizontal routing

tracks to connect the various logic and I/O modules. These

routing tracks are metal interconnects that may either be of

continuous length or broken into segments. Segments can be

joined together at the ends using antifuses to increase their

lengths up to the full length of the track.

Horizontal Routing

Horizontal channels are located between the rows of modules

and are composed of several routing tracks. The horizontal

routing tracks within the channel are divided into one or

more segments. The minimum horizontal segment length is

the width of a module-pair, and the maximum horizontal

segment length is the full length of the channel. Any segment

that spans more than one-third the row length is considered a

long horizontal segment. A typical channel is shown in

Figure 7. Undedicated horizontal routing tracks are used to

route signal nets. Dedicated routing tracks are used for the

global clock networks and for power and ground tie-off tracks.

Vertical Routing

Other tracks run vertically through the modules. Vertical

tracks are of three types: input, output, and long. Vertical

tracks are also divided into one or more segments. Each

segment in an input track is dedicated to the input of a

particular module. Each segment in an output track is

dedicated to the output of a particular module. Long

segments are uncommitted and can be assigned during

and two below), except near the top and bottom of the array

where edge effects occur. LVTs contain either one or two

segments. An example of vertical routing tracks and

segments is shown in Figure 8.

Antifuse Connections

An antifuse is a “normally open” structure as opposed to the

normally closed fuse structure used in PROMs or PALs. The

use of antifuses to implement a programmable logic device

results in highly testable structures as well as an efficient

programming architecture. The structure is highly testable

because there are no preexisting connections; temporary

connections can be made using pass transistors. These

temporary connections can isolate individual antifuses to be

programmed as well as isolate individual circuit structures to

be tested. This can be done both before and after

programming. For example, all metal tracks can be tested for

continuity and shorts between adjacent tracks, and the

functionality of all logic modules can be verified.

Four types of antifuse connections are used in the routing

structure of the ACT 3 array. (The physical structure of the

antifuse is identical in each case; only the usage differs.)

Table 1 shows four types of antifuses.

Examples of all four types of connections are shown in

Figures 7 and 8.

Module Interface

Connections to Logic and I/O modules are made through

vertical segments that connect to the module inputs and

outputs. These vertical segments lie on vertical tracks that

span the entire height of the array.

Module Input Connections

The tracks dedicated to module inputs are segmented by pass

transistors in each module row. During normal user

operation, the pass transistors are inactive, which isolates the

inputs of a module from the inputs of the module directly

above or below it. During certain test modes, the pass

transistors are active to verify the continuity of the metal

tracks. Vertical input segments span only the channel above

or the channel below. The logic modules are arranged such

that half of the inputs are connected to the channel above

and half of the inputs to segments in the channel below as

shown in Figure 9.

Module Output Connections

Module outputs have dedicated output segments. Output

segments extend vertically two channels above and two

channels below, except at the top or bottom of the array.

Output segments twist, as shown in Figure 10, so that only

four vertical tracks are required.

LVT Connections

Outputs may also connect to nondedicated segments called

Long Vertical Tracks (LVTs). Each module pair in the array

shares four LVTs that span the length of the column. Any

module in the column pair can connect to one of the LVTs in

the column using an FF connection. The FF connection uses

antifuses connected directly to the driver stage of the module

output, bypassing the isolation transistor. FF antifuses are

programmed at a higher current level than HF, VF, or XF

antifuses to produce a lower resistance value.

Antifuse Connections

In general every intersection of a vertical segment and a

horizontal segment contains an unprogrammed antifuse

(XF-type). One exception is in the case of the clock networks.

Clock Connections

To minimize loading on the clock networks, a subset of inputs

has antifuses on the clock tracks. Only a few of the C-module

and S-module inputs can be connected to the clock networks.

To further reduce loading on the clock network, only a subset

of the horizontal routing tracks can connect to the clock

inputs of the S-module.

Programming and Test Circuits

The array of logic and I/O modules is surrounded by test and

programming circuits controlled by the temporary special I/O

pins MODE, SDI, and DCLK. The function of these pins is

similar to all ACT family devices. The ACT 3 family also

includes support for two Actionprobe® circuits allowing

complete observability of any logic or I/O module in the array

using the temporary special I/O pins, PRA and PRB.

Package Thermal Characteristics

The device junction to case thermal characteristic is θjc, and

the junction to ambient air characteristic is θja. The thermal

characteristics for θja are shown with two different air flow

rates.

Maximum junction temperature is 150°C.

A sample calculation of the absolute maximum power

dissipation allowed for a CPGA 175-pin package at

commercial temperature and still air is as follows:

Power Dissipation

P = [ICC standby+ Iactive] * VCC + IOL * VOL * N + IOH *

(VCC – VOH) * M (1)

Where:

ICC standby is the current flowing when no inputs or

outputs are changing.

Iactive is the current flowing due to CMOS switching.

IOL, IOH are TTL sink/source currents.

VOL, VOH are TTL level output voltages.

N equals the number of outputs driving TTL loads to

VOL.

M equals the number of outputs driving TTL loads to

VOH.

An accurate determination of N and M is problematical

because their values depend on the design and on the system

I/O. The power can be divided into two components: static

and active.

Static Power Component

Actel FPGAs have small static power components that result

in lower power dissipation than PALs or PLDs. By integrating

multiple PALs/PLDs into one FPGA, an even greater

reduction in board-level power dissipation can be achieved.

The power due to standby current is typically a small

component of the overall power. Standby power is calculated

below for commercial, worst case conditions.

The static power dissipated by TTL loads depends on the

number of outputs driving high or low and the DC load

current. Again, this value is typically small. For instance, a

32-bit bus sinking 4 mA at 0.33 V will generate 42 mW with all

outputs driving low, and 140 mW with all outputs driving high.

The actual dissipation will average somewhere between as

I/Os switch states with time.

Active Power Component

Power dissipation in CMOS devices is usually dominated by

the active (dynamic) power dissipation. This component is

frequency dependent, a function of the logic and the external

I/O. Active power dissipation results from charging internal

chip capacitances of the interconnect, unprogrammed

antifuses, module inputs, and module outputs, plus external

capacitance due to PC board traces and load device inputs.

An additional component of the active power dissipation is

the totem-pole current in CMOS transistor pairs. The net

effect can be associated with an equivalent capacitance that

can be combined with frequency and voltage to represent

active power dissipation.

Equivalent Capacitance

The power dissipated by a CMOS circuit can be expressed by

the Equation 2.

Power (uW) = C

* V

CC2

* F (2)

Where:

is the equivalent capacitance expressed in pF.

is the power supply in volts.

F is the switching frequency in MHz.

Equivalent capacitance is calculated by measuring I

active

at a specified frequency and voltage for each circuit

component of interest. Measurements have been made over a

range of frequencies at a fixed value of V

. Equivalent

capacitance is frequency independent so that the results may

be used over a wide range of operating conditions. Equivalent

capacitance values are shown below.

Values for Actel FPGAs

To calculate the active power dissipated from the complete

design, the switching frequency of each part of the logic must

be known. Equation 3 shows a piece-wise linear summation

over all components.

Predictable Performance:

Tightest Delay Distributions

Propagation delay between logic modules depends on the

resistive and capacitive loading of the routing tracks, the

interconnect elements, and the module inputs being driven.

Propagation delay increases as the length of routing tracks,

the number of interconnect elements, or the number of

inputs increases.

From a design perspective, the propagation delay can be

statistically correlated or modeled by the fanout (number of

loads) driven by a module. Higher fanout usually requires

some paths to have longer lengths of routing track.

The ACT 3 family delivers the tightest fanout delay

distribution of any FPGA. This tight distribution is achieved

in two ways: by decreasing the delay of the interconnect

elements and by decreasing the number of interconnect

elements per path.

Actel’s patented PLICE antifuse offers a very low

resistive/capacitive interconnect. The ACT 3 family’s

antifuses, fabricated in 0.8 micron m lithography, offer

nominal levels of 200Ω resistance and 6 femtofarad (fF)

capacitance per antifuse.

The ACT 3 fanout distribution is also tighter than alternative

devices due to the low number of antifuses required per

interconnect path. The ACT 3 family’s proprietary

architecture limits the number of antifuses per path to only

four, with 90% of interconnects using only two antifuses.

The ACT 3 family’s tight fanout delay distribution offers an

FPGA design environment in which fanout can be traded for

the increased performance of reduced logic level designs.

This also simplifies performance estimates when designing

with ACT 3 devices.

Timing Characteristics

Timing characteristics for ACT 3 devices fall into three

categories: family dependent, device dependent, and design

dependent. The input and output buffer characteristics are

common to all ACT 3 family members. Internal routing delays

are device dependent. Design dependency means actual

delays are not determined until after placement and routing

of the user’s design is complete. Delay values may then be

determined by using the ALS Timer utility or performing

simulation with post-layout delays.

Critical Nets and Typical Nets

Propagation delays are expressed only for typical nets, which

are used for initial design performance evaluation. Critical

net delays can then be applied to the most time-critical

paths. Critical nets are determined by net property

assignment prior to placement and routing. Up to 6% of the

nets in a design may be designated as critical, while 90% of

the nets in a design are typical.

Long Tracks

Some nets in the design use long tracks. Long tracks are

special routing resources that span multiple rows, columns,

or modules. Long tracks employ three and sometimes four

antifuse connections. This increases capacitance and

resistance, resulting in longer net delays for macros

connected to long tracks. Typically up to 6% of nets in a fully

utilized device require long tracks. Long tracks contribute

approximatley 4 ns to 14 ns delay. This additional delay is

represented statistically in higher fanout (FO=8) routing

delays in the data sheet specifications section.

Timing Derating

ACT 3 devices are manufactured in a CMOS process.

Therefore, device performance varies according to

temperature, voltage, and process variations. Minimum

timing parameters reflect maximum operating voltage,

minimum operating temperature, and best-case processing.

Maximum timing parameters reflect minimum operating

voltage, maximum operating temperature, and worst-case

processing.
