WebPrimeTime has a speciﬁc behavior that is discussed in the documentation for the various path exception commands. Here is an excerpt from the set_multicycle_path manpage: The set_multicycle_path command is a point-to-point timing exception command. The command can override the default single-cycle timing relationship for one or more timing paths.
