Spartan 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 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).

Notes:
1.
Delay adder for CMOS Inputs option: for -3 speed grade, add 0.4 ns; for -4 speed grade, add 0.2 ns.
2.
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, see the pin-to-pin parameters in the Pin-to-Pin Input Parameters table.
3.
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.
