Spartan Pin-to-Pin Input Parameter Guidelines
Testing of switching parameters is modeled after testing
methods specified by MIL-M-38510/605. All devices are
100% functionally tested. Pin-to-pin timing parameters are
derived from measuring external and internal test patterns
and are guaranteed over worst-case operating conditions
(supply voltage and junction temperature). Listed below are
representative values for typical pin locations and normal
clock loading.

Notes:
1.
Setup time is measured with the fastest route and the lightest load. Hold time is measured using the furthest distance and a
reference load of one clock pin per IOB/CLB.
2.
IFF = Input Flip-flop or Latch
