In this paper, the authors propose a new method for test access and test scheduling in NoC-based system. It relies on a progressive reuse of the network resources for transporting test data to routers. They present possible solutions to the implementation of this scheme. They also show how the router testing can be scheduled concurrently with core testing to reduce test application time. Experimental results for the ITC'02 SoC benchmarks show that the proposed method can lead to substantial reduction on test application time compared to previous work based on the use of serial boundary scan. The method can also help to reduce hardware overhead.
