Overloaded regions in the routing space of a physical network are resolved via a routing procedure composed of a topological routing phase and a geometric routing phase. The overloads are resolved in the topological routing phase where the constraints of routing are less prohibitive. Multiple topological...http://www.google.de/patents/US8086987?utm_source=gb-gplus-sharePatent US8086987 - Method for resolving overloads in autorouting physical interconnections
