Abstract :
In this paper we propose a general framework for viewing a class of heuristics for track assignment in channel routing from a purely graph theoretic angle. Within this framework we propose algorithms for computing routing solutions using optimal or near optimal number of tracks for several well-known benchmark channels in the two-layer VH. Three-layer HVH, and multi-layer ViHi and Vi Hi+1 routing models. Within the same framework we also design an algorithm for minimizing the total wire length in the two-layer VH and three-layer HVH routing models
