Each property's search path information includes counterexample traces or proof artifacts identifying the search operations utilized to achieve a corresponding counterexample or proof object that proves/disproves the property. Search-path verification involves applying the stored search path information to the later-generated circuit design version, and determining if the same counterexample or proof object is achieved. The stored search path information is also utilized to perform efficient path-influenced search processes when the search-path verification process fails."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Formal verification using cached search path information to verify previously proved/disproved properties","description":"A formal verification tool that verifies multiple sequentially-generated versions of a core circuit design by obtaining search path information from the formal verification solver for each property th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10503853","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.
