【摘要】：目前采用IEEE 1500测试外壳的方法可以一定程度上解决NoC(Netword on Chip)路由器测试的问题,但当测试外壳的旁路出现一个以上的故障时,很可能导致一整条扫描链上的NoC路由器测试失败.针对该问题,本文通过提出一个深度优先最短路径算法得到从固定的扫描输入端到扫描输出端的最短路径,并通过提出的递归划分逐步求精法对路径进行筛选分块排序,构造多条扫描测试链将整个网络中的路由器分开测试.本文给出了测试外壳旁路故障的诊断和容错方法,使用节点分类测试方法实现对NoC路由器旁路故障的定位,并通过本文提出的测试外壳结构实现对故障旁路的容错.
[Abstract]:At present, the method of using IEEE 1500 to test the shell can solve the problem of testing the NoC(Netword on chip router to some extent, but when there is more than one fault in the bypass of the test shell, It is possible that the NoC router test on the whole scan chain will fail. In order to solve this problem, a depth-first shortest path algorithm is proposed to obtain the shortest path from the fixed scan input to the scanning output. By using the recursive partition refinement method proposed, the path is sorted in blocks, and several scan test chains are constructed to test routers in the whole network separately. In this paper, the fault diagnosis and fault tolerance method of the bypass circuit of the test shell is presented. The node classification test method is used to locate the bypass faults of NoC routers, and the fault tolerance of the fault bypass is realized through the test shell structure proposed in this paper.
