Abstract
Place-and-route (P&R) includes maintaining a set of local arrival time information and local required time information associated with a circuit layout; determining a candidate fix on a critical path in the circuit layout; statistically determining, using one or more computer processors, a set of one or more adjusted local slacks associated with a region affected by the candidate fix; and in the event that the set of one or more adjusted local slacks indicates that the candidate fix results in a timing improvement, accepting the candidate fix.
