Parameter
Combinatorial Delay of the longest path: time taken by the combinatorial circuit to
output
Setup time: time the synchronous input of the flip flop must be stable before the
active clock edge
Hold time: time the synchronous input of the flip flop must be stable after the active
clock edge
Clock to out delay: the amount of time taken by the flip flop to output after the active
clock edge.
Clock High Time: required minimum time the clock stays high
Clock Low Time: required minimum time that the clock stays low
Set Delay: time between when the flip flop is ”set” (high)
and when the output is consequently “set” (high)
