PSMMCMGC
PHMMCMGC
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.
IFF = Input Flip-Flop or Latch
Use IBIS to determine any duty-cycle distortion incurred using various standards.
