Zusammenfassung:A method, system, and computer program product for improving pin access in a design of an integrated circuit (IC) for multi-patterning lithography (MPL) are provided in the illustrative embodiments. A cell is placed in the IC design, the cell including a pin shape configured to connect a pin of the cell to a semi-conductor component in the IC design, the cell including a coloring conflict due to the pin shape and an other shape in the cell each being colored using a first color for fabricating onto a wafer using MPL. A net is routed to the pin shape without resolving the coloring conflict, wherein the routing routes the net using a first segment of the pin shape. The pin shape is modified after routing to resolve the coloring conflict to result in a modified cell.
