一种电路板网络化诊断测试的可测性设计方法

A Design-for-Testability Methodology of Network Oriented Diagnostic Test for PCBs

提出并实现了一种电路板网络化诊断测试的可测性设计方法.按照此方法设计的电路板,除了能够实现上电自检,还可以借助无线或有线网络由异地PC(个人电脑)机等远地终端来启动电路板测试、控制测试过程、查看测试流程、获得测试结果以及更新/升级测试程序,对电路板进行全面的诊断测试.为电路板的高质量测试提供了一条实用、有效的技术途径.

A design-for-testability methodology of network oriented diagnostic test for PCBs is proposed.The PCBs designed according to this methodology not only can realize self-inspection at power up but also can be controlled by remote terminal,such as PC,through wireless or cable network.The remote terminals can start circuit test,control test process,review test flow,obtain test results,renew/update test procedures.It provides a practical and effective approach for high quality test of PCBs.
