Executive Summary

Packet-based on-chip interconnection networks, or Network-on-Chips (NoCs) are progressively replacing global on-chip interconnections in Multi-processor System-on-Chips (MP-SoCs) thanks to better performances and lower power consumption. However, modern generations of MP-SoCs have an increasing sensitivity to faults due to the progressive shrinking technology. Consequently, in order to evaluate the fault sensitivity in NoC architectures, there is the need of accurate test solution which allows to evaluate the fault tolerance capability of NoCs. This paper presents an innovative test architecture based on a dual-processor system which is able to extensively test mesh based NoCs.
