WHAT IS SLACK WITH RESPECT TO SETUP??

a)Take the minmum delay values along the data path and maximum delay values along the clock path.

b)ARRIVAL TIME is always calculated along the data path.

c) ARRIVAL TIME =Propogation delay of the flip flop+propogation delay of the combinational logic+latency.

d)REQUIRED TIME is always calculated along the clock path.

e)REQUIRED TIME=Clock period + skew(differnce in arrival of clock b/w two flip flop)+latency+hold time of the flip flop.



SLACK(setup) = ARRIVAL TIME-REQUIRED TIME
