Integrated circuit including connection line

An integrated circuit comprising:

• a first cell including a first via;
• a second cell including a second via;
• and
• a connection line extending in a first direction and connecting the first via to the second via,
• wherein a length of the connection line is one of a via distance between the first via and the second via, a first length based on a minimum enclosure distance representing a region extending from an enclosure of each of the first via and the second via, and a second length that is a minimum length according to a design rule.

A method of designing an integrated circuit, the method comprising:

• placing a first cell including a first pin having a length determined based on a width of a first via and a minimum enclosure distance according to an enclosure rule, based on input data defining the integrated circuit;
• placing a second cell including a second pin having a length determined based on a width of a second via and the minimum enclosure distance, based on the input data;
• connecting the first pin to the second pin by using a connection line having a shortest length satisfying a design rule;
• and
• generating output data defining a layout of the integrated circuit, wherein the shortest length is one of a via distance between the first via and the second via,
• a first length based on the minimum enclosure distance, and a second length that is a minimum length of a wiring line set according to the design rule.
