Patent Images
1. A computer implemented method for forming a structural similarity group from a netlist of an integrated circuit comprising:
- taking a netlist representation of components forming all or part of an integrated circuit;
forming groups of the components included in the netlist representation which have at least a selected degree of structural similarity between each other; and
forming a structural similarity group which includes those groups of components identified as having at least the selected degree of structural similarity.

Abstract
A method for forming a structural similarity group from a netlist for use in performing a relative placement of components of an integrated circuit is described. Also described are a method for forming a relative placement of components of an integrated circuit using a structural similarity group and a method for modifying a relative placement of components of an integrated circuit by analyzing adjacent components for shared resources. In addition, methods for determining bus line routing, control line routing, and cleanup line routing for components of an integrated circuit are described.
