■ Software design support and automatic place-and-route provided by the Altera® MAX+PLUS® II development system for Windows-based PCs, as well as Sun SPARCstation, HP 9000 Series 700/800, and IBM RISC System/6000 workstations 

■ Additional design entry and simulation support provided by EDIF 2 0 0 and 3 0 0 netlist files, library of parameterized modules (LPM), Verilog HDL, VHDL, and other interfaces to popular EDA tools from manufacturers such as Cadence, Exemplar Logic, Mentor Graphics, OrCAD, Synopsys, Synplicity, and VeribestGeneral Description 

Altera’s Flexible Logic Element MatriX (FLEX®) family combines the benefits of both erasable programmable logic devices (EPLDs) and fieldprogrammable gate arrays (FPGAs). The FLEX 8000 device family is ideal for a variety of applications because it combines the fine-grained architecture and high register count characteristics of FPGAs with the high speed and predictable interconnect delays of EPLDs. Logic is implemented in LEs that include compact 4-input look-up tables (LUTs) and programmable registers. High performance is provided by a fast, continuous network of routing resources.
