An exhaustive test strategy based on flooding routing for NoC switches is presented in this paper. Some test-mode hardware is added to the switches to enable them to multicast their incoming packets thus examining all existing routes in the network. A test environment based on high-level switch faults is used which injects high level routing faults into the NoC-Under-Test and considers the total number of the packets received at the destination for fault detection. Experimental results show that that 100% fault coverage can be achieved with a small amount of test hardware overhead within an acceptable test time.
