CRITICAL REGION IDENTIFICATION
First Claim
1. A processing system to identify a region of a design block of an integrated circuit for redesign, the system comprising:
- a processor configured to divide the design block into grids, each of the grids including a associated number of logic elements, filter each of the grids based on a specified criticality criteria, the filtering including determining a total number (A) of the logic elements in each grid and a number (B) of the total number (A) of the logic elements in each grid that meet the specified criticality criteria, and identify the region as a set of two or more of the grids based on a result of the filtering; and
a display device configured to display the result of the filtering, wherein the processor determines, for each of the grids, a ratio as A/B and identifies the set of the two or more of the grids based on the respective ratio of the set of the two or more of the grids.

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.

3. A non-transitory computer program product comprising:
-
a tangible storage medium readable by a processor and storing instructions for execution by the processor to perform a method of identifying a region of a design block of an integrated circuit for redesign, the method comprising; dividing the design block into grids, each of the grids including a respective number of logic elements; filtering each of the grids based on a specified criticality criteria, the filtering including determining a total number (A) of the logic elements in each grid and a number (B) of the total number (A) of the logic elements in each grid that meet the specified criticality criteria; the identifying the region as a set of two or more of the grids based on a result of the filtering; and determining, for each of the grids, a ratio as A/B and digitizing the respective ratio for each of the grids. - View Dependent Claims (4)
