Product Obsolete/Under Obsolescence
Spartan-XL Family CLB RAM Synchronous (Edge-Triggered) Write Operation Guidelines
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
in the Xilinx Development System) and back-annotated to
the simulation netlist. All timing parameters assume
worst-case operating conditions (supply voltage and junc-
tion temperature). Values apply to all Spartan-XL devices
and are expressed in nanoseconds unless otherwise noted.
