XQ4000E Guaranteed Input and Output Parameters (Pin-to-Pin, TTL I/O)
Testing of switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Pin-to-pin timing parameters are derived from measuring external and internal test patterns and are
guaranteed over worst-case operating conditions (supply voltage and junction temperature). Listed below are representative
values for typical pin locations and normal clock loading. 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. Values apply to all XQ4000E/EX devices unless otherwise noted.
