    Abstract: A method is disclosed that includes the operations outlined below. A first criteria is determined to be met when directions of a first current and a second current around a first end and a second end of a metal segment respectively are opposite, in which the metal segment is a part of a power rail in at least one design file of a semiconductor device and is enclosed by only two terminal via arrays. A second criteria is determined to be met when a length of the metal segment is not larger than a electromigration critical length. The metal segment is included in the semiconductor device with a first current density limit depending on the length of the metal segment when the first and the second criteria are met.
