COLOR-INSENSITIVE RULES FOR ROUTING STRUCTURES

摘要

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.

1. A method comprising:
designating each of a plurality of first routes extending horizontally in an integrated circuit (IC) design positions as one of a plurality of colors, each of the plurality of first routes being placed on one of a plurality of equally spaced vertical positions of the IC design, wherein each of the first routes is generated according to a first design rule indicating a first separation distance between routes designated as different colors and a second separation distance between routes designated as same colors.
