Abstract
Method and apparatus for implementing a circuit design for an integrated circuit is described. In one example, matching elements between a modified version of the circuit design and an implemented version of the circuit design are identified. Recommended placements for the matching elements are established based on placement information from the implemented version of the circuit design. An initial placement of the modified version of the circuit design is generated using the recommended placements. Timing-critical elements in the initial placement are identified. Locked placements for elements other than the timing-critical elements are established. An optimized placement of the modified version of the circuit design is generated using the locked placements.
