Abstract:
The present disclosure describes an example method for cell placement in an integrated circuit (IC) layout design. The method includes partitioning a layout area into one or more contiguous units, where each unit includes a plurality of placement sites. The method also includes mapping a first set of pin locations and a second set of pin locations to each of the one or more contiguous units. The method further includes placing a cell in the one or more contiguous units, where the cell is retrieved from a cell library that includes a plurality of pin locations for the cell. The placement of the cell is based on an allocation of one or more pins associated with the cell to at least one of a pin track from the first plurality of pin locations, a pin track from second plurality of pin locations, or a combination thereof.
