Abstract
A preferred timing change is automatically selected from a set of candidate timing changes that can be made to address a short path violation in a circuit design. This involves determining an associated cost metric for each of the candidate timing changes, and identifying a lowest cost metric from the associated cost metrics. The candidate timing change associated with the lowest cost metric is selected from the set of candidate timing changes, for use as the preferred timing change. The associated cost metric may represent a cost per resolved source or destination register. Candidate timing changes may variously involve any of a number of techniques for introducing additional delays into a short path of the circuit.
