摘要
IEEE 1149.4的推出为混合信号测试提供了一个标准,推动了混合信号边界扫描测试技术的研究。简要介绍了IEEE 1149.4标准及混合信号测试方法,并根据标准定义的测试结构设计出一种混合信号边界扫描测试系统。经过测试验证,该系统能够对混合信号电路进行互连测试和参数测试,可实现准确的故障诊断,具有一定的实用价值。
The introduction of IEEE 1149.4 provides a standard for mixed-signal test and promotes the study on mixed-signal boundary-scan test technology.The IEEE 1149.4 standard and mixed-signal test methods are briefly introduced,a mixed-signal boundary scan test system is designed according to the test structures of standard definition.The test proves that the system can perform interconnect testing and parameter testing for mixed-signal circuits,enable accurate fault diagnosis,and has certain practical application.
