XQ4000E Wide Decoder 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). Values apply to all
XQ4000E devices unless otherwise noted.
The following guidelines reflect worst-case values over the
recommended operating conditions.

Notes:
1.
2.
These delays are specified from the decoder input to the decoder output.
Fewer than the specified number of pull-up resistors can be used, if desired. Using fewer pull-ups reduces power consumption but
increases delays. Use the static timing analyzer to determine delays if fewer pull-ups are used.
