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
