Abstract: An integrated circuit including: a first cell including first-a and second-a output pins, a first routing wire connecting the first-a output pin to the second-a output pin, a first-a via connecting the first-a output pin to the first routing wire, and a second-a via connecting the second-a output pin to the first routing wire; and a second cell including first-b and second-b output pins, a second routing wire connecting the first-b output pin to the second-b output pin, a first-b via connecting the first-b output pin to the second routing wire, and a second-b via connecting the second-b output pin to the second routing wire, wherein the first-a via is at a first-a position, the second-a via is at a second-a position, the first-b via is at a first-b position, the second-b via is at a second-b position different from each other.

Abstract: A standard cell library includes a first power rail, a second power rail, a third power rail, a first standard cell, and second standard cells. The first power rail extends in a first direction. The second power rail extends in the first direction, and is spaced apart from the first power rail by a predetermined spacing in a second direction perpendicular to the first direction. The third power rail extends in the first direction between the first power rail and the second power rail. The first standard cell has at least one cell having a first cell height, and is arranged between the first power rail and the second power rail. The second standard cells have at least two cells, each having a second cell height, that are in contact with each other in the second direction, and are in contact with the first standard cell in the first direction.
