Random variables are identified that model retiming labels representing a number and a direction of a register movement relative to a node on a retiming graph for the retimed design. A retiming constraint is identified for each edge on the retiming graph for the retimed design, wherein the retiming constraint reflects a relationship between the state variables and the random variables. A random variable that models a retiming label at a source of an edge is recursively substituted for a random variable that models a retiming label at a sink of the edge when a number of registers on the edge is unchanged after register retiming."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reducing constraints during rewind structural verification of retimed circuits","description":"A method for performing a rewind functional verification includes identifying state variables that model a number of registers on each edge of a retiming graph for an original design and a retimed des","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10489535","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.
