Accelerator Series FPGAs - ACT™ 3 Family

Actel Corporation 

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.
