Abstract: The invention relates to a method for manufacturing of electronic devices, such as very large scale integrated devices, having a channel. The channel routing is done based on a compositional approach in which initially all individual terminals are represented by individual nodes in a terminal vertical constraint graph. Individual constraints between individual terminals are represented by separate edges. This approach allows the resolution of difficult classes of routing problems in an efficient way.
