Abstract

This paper proposes a test planning method capable of reusing available processors as test sources and sinks, and the on-chip network as the access mechanism for the test of cores embedded into a system on chip. The resulting test time of the system is evaluated considering the number of reused processors, the number of external interfaces, and power dissipation. Experimental results for a set of industrial examples based on the ITC'02 benchmarks show that the cooperative use of both the on-chip network and the embedded processors can increase the test parallelism and reduce the test time.
