(b) during the physical design stage, analyzing the VLSI design based on said one or more criteria for non-essentiality, and finding those flip-flops that meet these criteria, wherein said analysis is performed at the gate level, independent from any higher level representation of the design; and (c) eliminating from the VLSI design those backup cells for all non-essential flip-flops that meet one or more of said criteria for non-essentiality, thereby leaving in the design only those backup cells for those flip-flops that do not meet any of said criteria."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for finding non-essential flip flops in a VLSI design that do not require retention in standby mode","description":"The invention relates to a method for reducing the number of flip-flops in a VLSI design that require data retention, thereby eliminating the respective backup cells for those flip flops, the method c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9727686","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.
