Spartan-6 Device Pin-to-Pin Input Parameter Guidelines
All devices are 100% functionally tested. The representative values for typical pin locations and normal clock loading are
listed in Table 68 through Table 74. Values are expressed in nanoseconds unless otherwise noted.

Notes:
1. Setup and Hold times are measured over worst case conditions (process, voltage, temperature). Setup time is measured relative to the Global Clock
input signal using the slowest process, highest temperature, and lowest voltage. Hold time is measured relative to the Global Clock input signal using
the fastest process, lowest temperature, and highest voltage.
2. IFF = Input Flip-Flop or Latch.
