Spartan and Spartan-XL FPGA Families Data Sheet
Spartan Family CLB RAM Synchronous (Edge-Triggered) Write Operation Guidelines
(continued)
All devices are 100% functionally tested. Internal timing
parameters are derived from measuring internal test pat-
terns. Listed below are representative values. For more
specific, more precise, and worst-case guaranteed data,
use the values reported by the static timing analyzer (TRCE
