    Spartan-XL Global Buffer Switching Characteristic Guidelines
    Testing of the 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 where one global clock input drives one vertical clock line in each accessible column, and where all
    accessible IOB and CLB flip-flops are clocked by the global clock net.
    When fewer vertical clock lines are connected, the clock distribution is faster; when multiple clock lines per column are driven
    from the same global clock, the delay is longer. For more specific, more precise, and worst-case guaranteed data, reflecting
    the actual routing structure, use the values provided by the static timing analyzer (TRCE in the Xilinx Development System)
    and back-annotated to the simulation netlist. These path delays, provided as a guideline, have been extracted from the static
    timing analyzer report. All timing parameters assume worst-case operating conditions (supply voltage and junction
    temperature).
