The method also includes identifying one or more post-CPPR critical paths based on the CPPR analysis, setting flags for critical nodes of the one or more post-CPPR critical paths, performing a design fix to address the one or more post-CPPR critical paths, and applying a set of rules based on the design fix and the flags to identify seed points among the critical nodes of the one or more post-CPPR critical paths. Invalidating and re-performing the CPPR analysis is done only for paths associated with the seed points."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Incremental common path pessimism analysis","description":"A method, system, and computer program product for performing incremental common path pessimism analysis in integrated circuit design includes performing common path pessimism removal (CPPR) analysis ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9836572","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
