Abstract
A method of designing an integrated circuit ('IC') is provided that includes placing an IC design, where the IC design includes a first element, a second element, and a path coupling the first and second elements, and routing the IC design. Further, the method includes obtaining at least one of resistivity data and capacitance data related to the path, and obtaining timing data related to the path. The method also includes using at least one of the resistivity data, the capacitance data, and the timing data to determine a critical dimension ('CD') bias to be applied to the path, and modifying the IC design, where modifying includes applying the CD bias to the path.
