Abstract
A method includes identifying a cell in the layout diagram as a violated cell that fails to pass one or more design rules related to IR drops, and classifying a root cause of the violated cell with a root cause class. The method also includes determining a searching area for searching safe region candidates, and finding a selected cell for moving based upon the root cause class of the root cause. The method further includes finding a safe region in the searching area for moving the selected cell, and moving the selected cell to the safe region if the safe region is found within the searching area.
