XQ4000E Horizontal Longline 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 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). Values apply to all XQ4000E/EX devices unless
otherwise noted.
The following guidelines reflect worst-case values over the recommended operating conditions.
Note 1:
These values include a minimum load. Use the static timing analyzer to determine the delay for each destination.
