Network-on-chip (NoC) communication fabrics will be increasingly used in many large multicore system-on-chip designs in the near future. A relevant challenge that arises from this trend is that the test costs associated with NoC infrastructures may account for a significant part of the total test budget. In this paper, we present a novel methodology for testing such NoC architectures. The proposed...
A novel method for on-line fault detection and location in network-on-chip (NoC) communication fabrics is introduced. This approach is able to distinguish between faults in the communication links and faults in the NoC switches. The idea is based on the use of code-disjoint routing elements, combined with parity check encoding for the inter-switch links. We analyze the effect of our method on relevant...
