Abstract: The method for extracting a capacitance from a layout is disclosed. The method decomposes a first net into a first and a second component, and decomposes a second net into a third and a fourth component. The method may obtain a first capacitance for the first component and the third component by a first method, and obtain a second capacitance for the second component and the fourth component by a second method different from the first method. A library with a plurality of entries may be provided, wherein each entry has a component pair comprising a component of the first net and a component of the second net, and a pre-calculated capacitance for the component pair. The first method may be to search a library to find a pre-calculated capacitance. The second method may be to obtain the first capacitance by an equation solver on the fly.

Abstract: The present disclosure relates to a method of RC extraction that provides for a fast development time and easy maintenance. In some embodiments, the method provides a graphical representation of an integrated chip layout having a plurality of integrated chip components. A plurality of pattern based graphical features are then determined. Respective pattern based graphical features define a structural aspect of an integrated chip component. One of the plurality of integrated chip components is defined as a pattern oriented function having inputs of one or more of the pattern based graphical features. The pattern oriented function determines a shape of the one of the plurality of integrated chip components based upon a relation between the plurality of inputs. By determining a shape of an integrated chip component using a pattern oriented function, the complexity of RC profiles can be reduced.
