Multiple derating factors are used for different STA sign off corners that have a base corner with two pairs of off-corners. The approach of the present invention does not add any extra work in cell library characterization, while in the mean it increases the accuracy of the delay calculation and the library generation at corners other than standard corners."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiple derating factor sets for delay calculation and library generation in multi-corner STA sign-off flow","description":"An apparatus and method to characterize a new process using an improved delay calculation.
