片上网络路由器的测试及其外壳旁路故障的诊断
Test for NoC Routers and Diagnose for Bypass of Its Test Wrapper
摘要
Abstract
The IEEE 1500 standard structure provides a test wrapper to test routers and a bypass to shield faulty routers.However,if a bypass fails,not only we cannot use it to tolerate fault,but also it will disturb other test responses in the same scan chain.To solve the problem,we propose a diagnostic method for bypass fault in routers' test wrapper in NoC.We use the Depth-first shortest path to get the shortest path from the scan-in port to the scan-out port,and we separate routers by using recursive partitioning stepwise refinement to construct multiple scan test chains.So the localization of bypass fault could be realized.Then we also propose an architecture to tolerate the bypass fault.关键词
