A standard cell evolution file is provided that stores electrical characteristic aging data of standard cells. An instance activity file is provided of simulated electrical activity at the pins of individual instances of the cells in the IC. The instance activity file and the device activity file are used to analyze device activity and consequent aging evolution of the devices, and then generate data for consequent aging evolution of the IC. The IC design can then be modified to account for the aging evolution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of designing integrated circuit that accounts for device aging","description":"A method of designing an integrated circuit (IC) includes simulating aging evolution of the IC by providing a standard cells library, and a device activity file of device electrical activity in the st","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8479130","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.
