Patent ID: 8612914

Claim:
An integrated circuit comprising: a first metal wire extending along a first routing track that is parallel to an axis, the first metal wire having a first width that is equal to a minimum metal width for metal wires defined by a design rule; a second metal wire extending along a second routing track that is parallel to the axis, the second metal wire having a width that is equal to the first width, the first routing track and the second routing track separated by one or more routing pitches, the routing pitch being an odd multiple of units for a manufacturing grid, the manufacturing grid representing a grid to which objects in a layout of the integrated circuit are aligned; a first cell instance including a plurality of cell pins, the cell pins including a first cell pin that is connected to the first metal wire, wherein the first cell pin extends in a first direction from the first routing track by at least half the first width and extends in a second direction from the first routing track by more than half the first width; and a second cell instance which is a flipped version of the first cell instance relative to the axis, the second cell instance including a second pin corresponding to the first pin and connected to the second metal wire.
