A fault-tolerant wormhole routing algorithm on mesh-connected processors is proposed. The proposed algorithm is based on the solid fault model and allows the fault polygons to be overlapped. The algorithm compares the position of fault region relative to current channel with the fault direction held of a misrouted message to route around overlapped fault polygons. A node deactivating algorithm to convert non-solid fault region into solid fault region is also proposed. The proposed routing algorithm uses four virtual channels and is deadlock and livelock free.
