摘要
IEEE1149.4标准为解决数模混合电路边界扫描测试提供了有效的方法;在IEEE1149.4标准提出的模拟互连测试结构的基础上,结合网络撕裂法故障诊断方法,实现对常规的复杂模拟无源网络进行符合IEEE1149.4标准的可测性设计和故障诊断,并通过实例仿真验证该方法的有效性。
IEEE1149.4 infrastructure has been aimed primarily for the boundary scan test of the mixed-signal circuit. This paper based on the infrastructure of the analog interconnect in IEEE1149.4 ,by using network decomposition method, accomplishes the design for test of the complex analog network,develops a new method of fault diagnosis. The application shows the efficiency of the method.
