Abstract
A power rail design method is disclosed that includes the steps outlined below. A plurality of power rails and a plurality of power domains corresponding thereto in an integrated circuit design file are identified. A design rule check for a plurality of circuit units in the integrated circuit design file is performed to retrieve a plurality of non-violating circuit regions that correspond to the power rails in each of the power domains. The power rails corresponding to at least part of the plurality of non-violating circuit regions in the integrated circuit design file are widened to occupy at least part of the non-violating circuit regions for the plurality of power rails.
