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.

Abstract: A portion of a layout of a single layer of an integrated circuit is to be multi-patterned. The patterns are divided into first and second groups, to be patterned on the single layer by a first mask or a second mask. For each portion of each pattern, a spacing relationship is determined between that portion and any adjacent pattern on either or both sides. A processor computes a first capacitance (C), resistance (R), or resistance-capacitance (RC) cost of assigning the first group to the first mask and the second group to the second mask, and a second cost of assigning the first group to the second mask and the second group to the first mask, based on the spacing relationships. The first group is assigned to the first mask and the second group to the second mask if the first cost is lower than the second cost.
