Abstract
Systems and methods are provided to optimize critical paths by modulating systemic process variations, such as regional timing variations in IC designs. A method includes determining a physical location of an element in the semiconductor chip design within the critical path. The method further includes modulating a systemic process variation of the semiconductor chip design to speed up the critical path based on a polysilicon conductor perimeter density associated with the element.
