Abstract
System and methods for achieving a timing closure in a design of an integrated circuit in presence of manufacturing variation. The method includes running a timing engine of a statistical timing analysis tool performing at least one optimization to fix at least one violation of at least one timing quantity at an integrated circuit location. The method includes choosing at least one optimization to apply and finding at least one failing timing quantity, where the quantity is failing due to at least one source of variability which the optimization would impact. The optimization is applied to at least one section of the path leading to the failing timing quantity, where the section contributes to the source of variability. Statistical sensitivity information in canonical form guides the optimization by providing a fully parameterized canonical form of the identified timing violations.
