POST-ROUTING COUPLING FIXES FOR INTEGRATED CIRCUITS

A method for rerouting a wire in an integrated circuit includes determining a wire coupling a first circuit element to a second circuit element is experiencing capacitive coupling effects with one or more other wires; removing the wire from a netlist; dividing the structure into a routing grid; defi...

Zusammenfassung:A method for rerouting a wire in an integrated circuit includes determining a wire coupling a first circuit element to a second circuit element is experiencing capacitive coupling effects with one or more other wires; removing the wire from a netlist; dividing the structure into a routing grid; defining a first and second wire types; associating a penalty with each wire type; determining all possible paths through the routing grid between the first circuit element and the second circuit element; determining a weighted length for each path; and selecting the path having the lowest weighted length.
