Abstract:
A method for compacting a wiring layout pattern, the pattern including a plurality of wirings including at least a first wiring and a second wiring, each wiring having a plurality of first layer wires extending in a first direction and a plurality of second layer wires extending in a second direction generally perpendicular to the first direction, wherein the method comprises the steps of: a) arranging two first layer wires of the same wiring at different locations and being connected to each other by a second layer wire and identifying first layer wires that obstruct a line extending in the first direction from one of the two first layer wires of the first wiring;b) forming an enlarged area between the first layer wire from which said line extends and the identified first layer wire that obstructs said line; c) shifting the other one of the two first layer wires to the enlarged area to be aligned along said line, such that the two first layer wires of first wiring are connected to each other; d) establishing an original layout area of the other one of the two first layer wires as an open area; and e) deleting the second layer wire previously connecting the two first layer wires and connecting the two first layer wires to form a single first layer wire.
