Timing Diagrams

Signal
Clock
Bus
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.
Timing relationships in this diagram are drawn without proportion to actual delay.
