1. A computer implemented method for forming a relative placement of components of an integrated circuit from a netlist comprising:

  • taking a netlist representation of components forming all or part of an integrated circuit;

    forming groups of components within the netlist which have at least a selected degree of structural similarity between each other;

    making a structural similarity group which includes those groups of components identified as having at least the selected degree of structural similarity;

    performing an initial relative placement of the groups of components;

    reducing wire lengths between components of initial relative placement; and

    adding to the relative placement those components from the netlist which were not included in the groups of components.
