I am working for the first time on timing closure probs. I have a very strange values generated . i am using a freq of 1.25 ns .
and wen i see the slack report post placed it shows me a +ve slack of 2+ i am confused abt this values. the slack valus is more then the freq. i am using.
this the formula for find slack
slack = required time - arrivel time
if get the positive value of slack means no error ( time is meet )
if it is nagetive value time is not meet
thanks
