CONTINUOUS GLOBAL REPRESENTATION OF LOCAL DATA USING EFFECTIVE AREAS IN INTEGRATED CIRCUIT LAYOUTS

Abstract:

Embodiments provide a method for representing a layout of an integrated circuit. In example embodiments, a method includes determining multiple regions of an integrated circuit (IC) layout design based on one or more parameters. In embodiments, at least one region of the multiple regions has a characteristic. The example method further includes determining multiple areas associated with the multiple regions. Each area of the multiple areas has a characteristic of a region of the multiple regions. The example method further includes assigning a first set of values to locations of the IC layout design outside the multiple areas, assigning a second set of values to locations of the IC layout design within the multiple areas, and, in response to a determination that a location of the IC layout design is located in two or more overlapping areas of the multiple plurality of areas, determining a value to assign to the location based at least in part on values of the two or more overlapping areas of the multiple areas. The example method further includes generating, using a processor, an integrated circuit (IC) representation of the IC layout design based at least in part on the first values, the second values, and the value.
