Abstract

See full text

Some embodiments of the invention provide a method of decomposing a region of an intergrated circuit ('IC') layout. The method defines several nodes in the region. The method then specifies a plurality of edges in the region. Each edge is between a pair of nodes, and some edges are neither perpendicular nor parallel to some of the edges. The method uses the edges to define routes in the region.
