Patent number: 10740520Abstract: The disclosure relates to a method, computer program product or data processing system for performing graph-based static timing analysis, GBA, of an integrated circuit design having a set of timing paths. The method comprises identifying a subset of the set of timing paths and performing path-based analysis, PBA, of the subset of timing paths to determine at least one PBA timing parameter for each timing path of the subset of timing paths. The method further comprises determining at least one optimized GBA timing parameter for at least one timing path of the subset of timing paths by minimizing a function that is based on a difference between the at least one optimized GBA timing parameter and the at least one PBA timing parameter of the at least one timing path.Type: GrantFiled: April 14, 2017Date of Patent: August 11, 2020Assignee: Synopsys, Inc.Inventors: Chunyang Feng, Jianquan Zheng, Fulin Peng
