Abstract :
Reusing on-chip functional interconnects as test access mechanism (TAM) appeared usual these days. One of the most important functional interconnects for highly crowded future system-on-chips (SoCs) is network-on-chip (NoC). Several NoC architectures including router and network interface (NI) have been proposed. They allow narrowcast and multicast of packets, in-order packet delivery, guaranteed throughput and best-effort services. Exploiting the preceding research, we present here a parallel test method and a manipulated scheduling method for NoC-based SoCs, while reusing NoC as TAM, with the goal of reducing overall test time. The proposed test method is compared with previous works using some of ITC´02 benchmark circuits which showed significant test time reduction.
