ACT2 Family FPGAs
Description
The ACT2 family represents Actels second generation of
field programmable gate arrays (FPGAs). The ACT 2 family
presents a two-module architecture, consisting of C-modules
and S-modules. These modules are optimized for both
combinatorial and sequential designs. Based on Actels
patented channeled array architecture, the ACT 2 family
provides significant enhancements to gate density and
performance while maintaining downward compatibility
with the ACT 1 design environment and upward
compatibility with the ACT 3 design environment. The
devices are implemented in silicon gate, 1.0-µm, two-level
metal CMOS, and employ Actels PLICE® antifuse
technology. This revolutionary architecture offers gate array
design flexibility, high performance, and fast
time-to-production with user programming. The ACT 2
family is supported by the Designer and Designer Advantage
Systems, which offers automatic pin assignment, validation
of electrical and design rules, automatic placement and
routing, timing analysis, user programming, and diagnostic
probe capabilities. The systems are supported on the
following platforms: 386/486PC, Sun, and HP
workstations. The systems provide CAE interfaces to the
following design environments: Cadence, Viewlogic®,
Mentor Graphics®, and OrCAD.
