Abstract
A database is constructed based on a batch PBA performed on a plurality of paths of an integrated circuit. A local PBA is performed on a portion of a selected path. A selected optimization move is identified on the portion of the selected path, based on a result of the local PBA that best meets a set of constraints. A path-wide PBA is performed for an updated path that is based on the selected path incorporating the selected optimization move. The selected optimization move is committed in a netlist associated with the integrated circuit.
