XQ4028EX IOB Input 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 XQ4000EX devices unless
otherwise noted.
Note 1: For CMOS input levels, see the
“XQ4028EX Input Threshold Adjustments” on page 27
.
Note 2: For set-up and hold times with respect to the clock input pin, see the Global Low Skew Clock and Global Early Clock Set-up and Hold
tables on
