Abstract:

In order to reduce the test time of NoC,the problem of how to use the limited on-chip resources to maximize parallel test in power constraints is discussed.This paper presents a method for using the cloud evolution algorithm to schedule the IP cores,which effectively improves the test efficiency.The method reuses the on-chip network as TAM (test access mechanism),using non-preemptive test and XY routing mode and optimizing the allocation of IP cores in each TAM by the cloud evolution algorithm.Experimental results from the ITC'02 system-on-chip benchmarks show that this method effectively reduces the test time and improves the test efficiency.
