Abstract

Methodologies and an apparatus enabling a generation of color undeterminable polygons in IC designs are disclosed. Embodiments include: determining a plurality of first routes extending horizontally in an IC design, each of the plurality of first routes being placed on one of a plurality of equally spaced vertical positions of the IC design; determining whether a second route overlaps one of the vertical positions of the plurality of equally spaced vertical positions; and selecting a design rule for the second route based on the determination of whether the second route overlaps.
