Abstract

A method is disclosed for determining the placement of circuit elements in an integrated circuit where the circuit elements are initially represented by a netlist. The method preferably includes the steps of providing predetermined ordering constraints that indicate the preferred relative locations of the circuit elements that are represented in the netlist, partitioning the circuit elements from the netlist in accordance with a predetermined balancing criterion; determining the value of a cost function associated with the partitioning steps, and selecting a particular partition based upon the value of the cost function.
