    Spartan and Spartan-XL Families Field Programmable Gate Arrays
    Spartan CLB RAM Synchronous (Edge-Triggered) Write Operation Guidelines (continued)
    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 Development System) and back-annotated to the simulation netlist. All timing
    parameters assume worst-case operating conditions (supply voltage and junction temperature). Values apply to all Spartan
    devices and are expressed in nanoseconds unless otherwise noted.
    Note 1: Read Operation timing for 16 x 1 dual-port RAM option is identical to 16 x 2 single-port RAM timing.
