Timing Diagrams

Timing_Specifications

All timing specifications consist of the relationship between a reference clock and a
signal:
There are bussed and non–bussed signals. Non–bussed signals separately
illustrate 0–to–1 and 1–to–0 transitions.
Inputs have setup/hold times versus clock rising.
Outputs have switching time relative to either clock rising or clock falling.
Note:
