The method also includes making a backup copy of the design layout file prior to converting the identified off-grid pattern into an on-grid pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of design rule check for off-grid irregular layout with on-grid design rule check deck","description":"A method for DRC verification of a design layout file comprising off-grid patterns includes identifying an off-grid pattern having one or more off-grid sides, outwardly expanding the one or more off-g","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9798851","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.
