Table 23: Input Register Cell
Parameter: Input Cell Register Only
Input register setup time: time the synchronous input of the flip flop must be
stable before the active clock edge
Input register hold time: time the synchronous input of the flip flop must be
stable after the active clock edge
Input register clock to out: time taken by the flip flop to output after the active
clock edge
Input register reset delay: time between when the flip flop is “reset”(low) and
when the output is consequently “reset” (low)
Input register clock enable setup time: time “enable” must be stable before
the active clock edge
Input register clock enable hold time: time “enable” must be stable after the
active clock edge
