Abstract
Processing a circuit design includes determining that an operating frequency for a first placement and routing for the circuit design does not exceed a target operating frequency, distinguishing between loop paths and feed-forward paths in the circuit design, and, responsive to determining that the operating frequency does not exceed the target operating frequency, relaxing timing constraints of the feed-forward paths using a processor. A second placement and routing is performed on the loop paths and the feed-forward paths of the circuit design.
