1. A method for achieving signoff closure for a design layout for an integrated circuit (IC), the method comprising: analyzing the design layout using a signoff algorithm in a signoff tool to detect a set of violation paths and to generate context data for one or more of the set of violation paths, wherein each of the set of violation paths consists of a signal path in the design layout exhibiting a violation of a design specification for the IC, and wherein the context data comprises violation information other than violation path information; implementing changes to the design layout in an implementation tool based on the set of violation paths and the context data; and repeating the steps of analyzing and implementing until the design layout meets the design specification according to the signoff algorithm.
