Introduction
XC4000 Series high-performance, high-capacity Field Pro-
grammable Gate Arrays (FPGAs) provide the benefits of
custom CMOS VLSI, while avoiding the initial cost, long
development cycle, and inherent risk of a conventional
masked gate array.
The result of thirteen yearsofFPGAdesignexperience and
feedback from thousands of customers, these FPGAs com-
bine architectural versatility, on-chip Select-RAM memory
with edge-triggered and dual-port modes, increased
speed, abundant routing resources, and new, sophisticated
software to achieve fully automated implementation of
complex, high-density, high-performance designs.
The XC4000E and XC4000X Series currently have 20
members, as shown in Table 1.
