INTEGRATED CIRCUIT DESIGN METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18356426 titled 'INTEGRATED CIRCUIT DESIGN METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT

Simplified Explanation

The patent application describes a method for analyzing and improving the performance of integrated circuit (IC) layouts.

  • The method involves creating groups of paths in an IC layout diagram, where each group is characterized by a unique dominant feature among multiple features of the paths.
  • The paths are tested, and if any path fails, modifications are made to the IC layout diagram, library cells, or the manufacturing process for the corresponding IC.
  • The features of the paths include numerical and categorical values.
  • The categorical values are converted into numerical values for analysis.
  • The groups of paths are created based on the numerical values of the features.
  • This method allows for targeted analysis and modification of specific groups of paths to improve the overall performance of the IC layout.


Original Abstract Submitted

A method includes creating a plurality of groups of paths from a plurality of paths in an integrated circuit (IC) layout diagram. Each group has a unique dominant feature among a plurality of features of the plurality of paths. The method further includes testing a path in a group and, when the path fails, modifying at least one of the IC layout diagram, at least a portion of at least one library having cells included in the IC layout diagram, or a manufacturing process for manufacturing an IC corresponding to the IC layout diagram. The plurality of features includes a numerical feature having a numerical value, and a categorical feature having a non-numerical value. The non-numerical value is converted into a converted numerical value. The plurality of groups is created based on the numerical value of the numerical feature, and the converted numerical value of the categorical feature.
