Abstract:
1. A method for performing leakage calculations, the method comprising: receiving, at one or more computer systems, information specifying an integrated circuit; determining, with one or more processors associated with the one or more computer systems, a neighborhood of shapes associated with the integrated circuit, wherein determining the neighborhood of shapes comprises: determining a first set of spacings between a boundary of an internal shape of a first cell and a boundary of the first cell, determining a second set of spacings between the boundary of the first cell and a boundary of a shape of a second cell, and characterizing a lithography process using the first and second set of spacings; and generating, with the one or more processors associated with the one or more computer systems, leakage information associated with the integrated circuit based on calculating leakage in the integrated circuit using a simulation of the characterized lithography process.
