Continuous global representation of local data using effective areas in integrated circuit layouts

Abstract:

A method for representing a layout of an integrated circuit (IC) includes, in part, determining multiple regions of the IC layout based on one or more parameters, determining multiple areas associated with the multiple regions where each area has a characteristic of a region of the multiple regions, assigning a first set of values to locations of the IC layout outside the multiple areas, assigning a second set of values to locations of the IC layout within the multiple areas, and, in response to a determination that a location of the IC layout is in two or more overlapping areas of the multiple areas, determining a value to assign to the location in accordance with the values of the two or more overlapping areas. The method further includes generating data representative of the IC layout design in accordance with the first and second set of values, and the assigned value.
