A semiconductor device includes a plurality of cells. Each of the cells has a respective outer cell boundary defined to circumscribe the cell in an orthogonal manner. Also, each of the cells includes circuitry for performing one or more logic functions. This circuitry includes a plurality of conductive features defined in one or more levels of the cell. One or more of the conductive features in at least one level of a given cell is an encroaching feature positioned to encroach by an encroachment distance into an exclusion zone. The exclusion zone occupies an area within the cell defined by an exclusion distance extending perpendicularly inward into the given cell from a first segment of the outer cell boundary. The exclusion distance is based on a design rule distance representing a minimum separation distance required between conductive features in adjacently placed cells on the semiconductor device.
