三维设计的片上网络(Network-on-chip)是当前的热点研究专题。提出一种有效的片上网络路由器和互连测试方法显得非常重要。文章通过对路由器分类,提出了一种新的片上网络路由器测试方法。将不同输入、输出端口的路由器分为不同的类。相同分类的路由器是同构的,它们的测试集也是相同的。针对相同路由器提出了一个基于单播的多播方案(Unicast-based Multicast),并提出了新的互连测试方法。实验结果表明文章方法是有效的。 Three-dimensional design of the network (on-chip) is the current hot research topic. It is very important to propose an effective on-chip network router and interconnect test method. By classifying routers, this paper proposes a new method for testing on-chip network routers. Will be different input and output ports of the router is divided into different categories. The same category of routers are isomorphic, their test set is the same. Aiming at the same router, a unicast-based multicast scheme is proposed and a new interconnection testing method is proposed. Experimental results show that the method is effective.
