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.

Architecture
Logic Modules
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.
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:
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.

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/O Modules
Figure 2 • C-Module Diagram
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.
1-184
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
A c c e l e ra to r S e ri e s F P G A s – A C T ™ 3 Fami l y
routing. Each output segment spans four channels (two above
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.
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
XF
Horizontal-to-Vertical Connection
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.

“Fast” Vertical Connection
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.
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.
Table 1 • Antifuse Types
Examples of all four types of connections are shown in
Figures 7 and 8.
Clock Connections
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.
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.
Module Input Connections
Programming and Test Circuits
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
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.

Power Dissipation
P = [ICC standby+ Iactive] * VCC + IOL * VOL * N + IOH *
(VCC – VOH) * M
Static Power Component
(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.
1-190
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.
ICC
2mA
VCC
5.25 V
Power
10.5 mW
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.
A c c e l e ra to r S e ri e s F P G A s – A C T ™ 3 Fami l y
Active Power Component
Where:
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.

at a specified frequency and voltage for each circuit

range of frequencies at a fixed value of VCC. 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.

Determining Average Switching Frequency
To determine the switching frequency for a design, you must
have a detailed understanding of the data input values to the
circuit. The following guidelines are meant to represent
worst-case scenarios so that they can be generally used to
predict the upper limits of power dissipation. These
guidelines are as follows:

Predictable Performance:
Tightest Delay Distributions
Timing Characteristics
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 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.

3. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.

Notes:
1. VCC = 3.0 V for 3.3V specifications.
2. For dual-module macros, use tPD + tRD1 + tPDn , tCO + tRD1 + tPDn or tPD1 + tRD1 + tSUD , whichever is appropriate.
3. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.

3. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.

Note:
1. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.
