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.
