    Spartan-XL CLB RAM Synchronous (Edge-Triggered) Write Operation Guidelines (cont.)
    Testing of switching parameters is modeled after testing
    methods specified by MIL-M-38510/605. All devices are
    100% functionally tested. Internal timing parameters are
    derived from measuring internal test patterns. 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 Develop-
    ment System) and back-annotated to the simulation netlist.
    All timing parameters assume worst-case operating condi-
    tions (supply voltage and junction temperature). Values
    apply to all Spartan-XL devices and are expressed in nano-
    seconds unless otherwise noted.
