XQ4000XL IOB Output Switching Characteristic Guidelines
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.
These path delays, provided as a guideline, have been
extracted from the static timing analyzer report. All timing
parameters assume worst-case operating conditions (sup-
ply voltage and junction temperature). For Propagation
Delays, slew-rate = fast unless otherwise noted. Values are
expressed in nanoseconds unless otherwise noted.
