NoC Reconfiguration for Utilizing the Largest Fault-free Connected Sub-structure

This paper proposes an offline test strategy for finding the largest fault-free connected sub-structure of a mesh-based NoC. Faulty switch ports are found by flooding the NoC with test packets. Then, NoC routers are reconfigured according to the degraded NoC structure to route incoming packets.
