A Fast Test Architecture for Asynchronous Network-on-Chip Routing Networks

ANoC (Asynchronous Network-on-Chip) has been developed to solve problems of large number of cores in SoC (System-on-Chip) by giving asynchronism to every core. This new architecture requires new Testing methods different from the existing SoC Test, and it freshly needs the test of router and routing networks. This paper first offers high-speed testing architecture that tests more than one routers and networks at the same time in the 2-D mesh topology. Then, the structure of wrapper for realization of this method is explained. We show that the more number of routers is, the more effective performance is by checking the clock count for test of various ANoCs that have several sizes.
