Identify those of the nets of the putative integrated circuit design traversing through the at least one congested region, to obtain a plurality of candidate nets for demotion. Demote a plurality of selected nets, selected from the plurality of candidate nets for demotion, from an upper routing layer of the putative integrated circuit design to a lower routing layer of the putative integrated circuit design. At least some of the plurality of selected nets experience a loss of timing quality of result after the demoting."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Routing layer re-optimization in physical synthesis","description":"To increase the efficiency of electronic design automation, at an end point of physical design synthesis optimization flow for a putative integrated circuit design having a plurality of nets, identify","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11983477","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.
