One aspect provides an input/output cell. The input/output cell, in one example, includes an input/output layout boundary delineated on a substrate, wherein the input/output layout boundary defines a first side parallel and opposing a second side, a third side parallel and opposing a fourth side, wherein the first and second sides are substantially perpendicular the third and fourth sides. The input/output cell, in this example, further includes input/output transistors positioned within the input/output layout boundary over the substrate. The input/output cell, in this example, further includes first and second power conductors and first and second ground conductors located over the substrate, the first power conductor and first ground conductor extending entirely between the first and second sides and the second power conductor and second ground conductor extending entirely between the third and fourth sides.
