Abstract

The present disclosure is directed to a method of selecting cells in an integrated circuit for logic restructuring of an original design. The original design includes a set of parameters. The method includes forming a restructuring set that will include the selected cells for logic restructuring, and a candidate set. The restructuring set includes restructuring cells with an initial cell. The restructuring set is adapted to accept additional cells identified as restructuring cells. The candidate set is adapted to include candidate cells, where each candidate cell in the candidate set is connected to at least one of the restructuring cells in the restructuring set. The candidate set is adapted to remove candidate cells from the candidate set. The restructuring set is adapted to accept selected removed candidate cells as identified restructuring cells if a corresponding parameter is included in the set of parameters.
