    Abstract: A method of designing a semiconductor integrated circuit (IC) is provided as follows. A standard cell library is generated. The standard cell library includes characteristic information for a plurality of standard cells. The characteristic information includes a characteristic of each standard cell. A characteristic change region is detected. The characteristic change region includes at least one of the plurality of standard cells by comparing characteristics of standard cells to be placed adjacent to the characteristic change region, based on the standard cell library. A characteristic of the at least one standard cell included in the detected characteristic change region is changed to one of the characteristics of the standard cells to be placed adjacent to the characteristic change region to update the standard cell library. A plurality of standard cells of the updated standard cell library is placed.

    Abstract: A standard cell library and a method of using the same may include information regarding a plurality of standard cells stored on a non-transitory computer-readable storage medium, wherein at least one of the plurality of standard cells includes a pin through which an input signal or an output signal of the at least one standard cell passes and including first and second regions perpendicular to a stack direction. When the via is disposed in the pin, the second region can provide a resistance value of the via smaller than that of the first region. The standard cell library may further include marker information corresponding to the second region.
