XQ4000E IOB Input Switching Characteristic Guidelines (continued)
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.
Note 1:
Input pad setup and hold times are specified with respect to the internal clock (IK). For setup and hold times with respect to
the clock input pin, see the pin-to-pin parameters in the Guaranteed Input and Output Parameters table.
Voltage levels of unused pads, bonded or unbonded, must be valid logic levels. Each can be configured with the internal
pull-up (default) or pull-down resistor, or configured as a driven output, or can be driven from an external source.
Timing is based on the XQ4005E. For other devices see the static timing analyzer.
