Circuit’s Behavior
The steady-state behavior of a circuit is the value of the
output after the inputs have been stable for a long time.
The transient behavior of a circuit is the value of the
output while (or soon after) the inputs change.
The glitch is a (often undesirable) short pulse produced
in the output during a transient phase.
If a circuit has the possibility of producing a glitch,
the circuit has a hazard.
