Abstract:

In order to solve the problem of how to select 3D NoC test ports so that we can improve test efficiency,a method is proposed in this paper.This method uses the evolution algorithm based on the cloud model to select 3D NoC test ports and allocate the test data of IP cores to the test ports reasonably,and then tests the IP cores in parallel under power constraint by reusing the on-chip network as the test access mechanism and using the XYZ routings algorithm and non-preemptive test scheduling to achieve improve the test efficiency.Experiment results demonstrate that the proposed method can improve the precision for searching the test ports position and combination,and reduces the test time efficiently.
