Summary:A method for automatically creating a global routing solution for an integrated circuit. The method includes generating n original population of GR solutions. In one or more subsequent phases the method generates succeeding populations of GR solutions. The generation of each succeeding population includes determining a plurality of base GR solutions from the current population of GR solutions, determining a plurality of DRC hotspot areas within the plurality of base GR solutions, determining a plurality of patching GR solutions from which patches may be extracted, and hybridizing patching of GR solutions into base GR solutions.
