tPD
Combinatorial delay: time taken by the combinatorial circuit to output
0.257
tSU
Setup time: the amount of time the synchronous input of the flip flop must be stable before
the active clock edge
0.22
thl
Hold time: the amount of time the synchronous input of the flip flop must be stable after the
active block edge
0
tCLK
Clock to out delay: the amount of time the synchronous input of the flip flop must be stable
after the active block edge
0.255
tCWHI
Clock High Time: the length of time that the clock stays high
0.46
tCWLO
Clock Low Time: the length of time that the clock stays low
0.46
tSET
Set Delay: amount of time between when the flip flop is ”set” (high)
and when Q is consequent “set” (high)
0.18
tRESET
Reset Delay: amount of time between when the flip flop is ”reset” (low) and when Q is
consequent “reset” (low)
0.09
tSW
Set Width: length of time that the SET signal remains high
(low if active low)
0.3
tRW
Reset Width: length of time that the RESET signal remains high
(low if active low)
0.3
