Abstract
A system and method to implement an integrated circuit design are described. The method includes obtaining a timing database of current timing slack values based on current cell selection, placement, and routing for a plurality of cycles defined by a plurality of cycle boundaries, each cycle representing devices between a corresponding pair of the plurality of cycle boundaries, identifying candidate cycle boundaries among the plurality of cycle boundaries for slack redistribution, every one of the candidate cycle boundaries being associated with a positive timing slack, and selecting redistribution cycle boundaries among the candidate cycle boundaries. A modified timing database is generated based on redistributing the positive timing slack associated with the redistribution cycle boundaries, and power recovery is performed using the modified timing database to reduce power at one of more of the redistribution cycle boundaries.
