Some embodiments of the invention provide a method of routing nets in a region of a layout with multiple layers. The method defines a routing graph that has several of nodes on plurality of layers, where each node represents a sub-region on a layer. In the graph, there is a set of edges between the nodes on each layer. On one layer, there is at least one set of edges that are neither orthogonal nor parallel to a set of edges on another layer. The method uses this routing graph to identify routes.
