Nettet21. apr. 2011 · Setup is defined as the amount of time required for the signal to be valid before the capture clock edge. This is effected by delay of the source flop and combo logic. If the signal is too close to the capture clock edge (I.e lots of delay) then it will violate setup time. max delay / slow libraries are needed to verify this path.
