This paper chooses USB logic analyzer as a typical tested object, and carries through a second develop to design it supporting IEEE 1149.1 boundary-scan function for testability.
The paper also discusses two intelligent fault diagnostic methods: expert system intelligent fault diagnostic method and boundary-scan technique intelligent fault diagnostic method.
本文还讨论了两种智能故障诊断技术，即专家系统智能故障诊断技术和边界扫描测试智能故障诊断技术。
