Abstract

A method and system to identify a region of a design block of an integrated circuit for redesign are described. The method includes dividing the design block into grids, each of the grids including a corresponding number of logic elements. The method also includes filtering each of the grids based on a specified criteria, the filtering including determining a number (B) of the corresponding logic elements among a total number (A) of the logic elements in each grid that meet the specified criteria. The region is a set of two or more of the grids based on a result of the filtering.
