This paper presents algorithms for Interconnecting the terminals In a channel using a minimum amount of crosstalk In minimum area. Algorithms are developed for grid-based routing models In two-layer (VH), three-layer (VHV and HVH), and four-layer (VHVH) channels. Our channel routers use only no-dogleg wires and resolve vertical constraints efficiently. The routers are executed for several well-known benchmark channel Instances and results obtained are highly encouraging. © 2004 IEEE.
