Abstract

Systems and methods are provided for refining a design cycle for an integrated circuit. An integrated circuit design is generated. A plurality of non-critical paths within the integrated circuit design are identified. A set of at least one of the plurality of non-critical paths is modified to produce a modified design in which the sensitivity of each of the set of non-critical paths to at least one parameter is enhanced. Each parameter is either a design parameter or a process parameter. An integrated circuit is fabricated according to the modified design. The fabricated integrated circuit is evaluated to measure a set of timing data representing each of the plurality of non-critical paths. The value of the parameter is determined from the measured set of timing data.
