ACEX 1K devices are supported by Altera development systems, which
are 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 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 system includes DesignWare
functions that are optimized for the ACEX 1K device architecture.
The Altera development systems run on Windows-based PCs and Sun
SPARCstation, and HP 9000 Series 700/800 workstations.

Functional
Description
Each ACEX 1K device contains an enhanced embedded array that
implements memory and specialized logic functions, and a logic array
that implements general logic.
The embedded array consists of a series of EABs. When implementing
memory functions, each EAB provides 4,096 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.
