摘　　要：为了保证通用ATS中测试资源到通用测试接口间信号传输的可靠性以及通用测试接口上测试资源的可用性,提出了基于环绕BIT技术的ATS自检方案;该自检方案通过分析通用ATS内部各种测试资源的特性,并按照信号的特性以及自检的实际需求进行了分类,充分利用集成芯片设计了各类测试资源相应的自检电路,采用LabWindows/CVI开发了完整的自检软件,并以电源自检为例介绍软件设计;实际证明该方案可以满足通用ATS自检的需求,具有极大的实用价值。In order to ensure reliability of signal transmission from test resource to test interface and usability of test resources on interface, presented ATS self--test scheme based on surround BIT; analyzed characteristic of ATS test resources, sorted according to signal char- acteristic and actual requirement, designed self--test circuit using integrated chips, developed self--test software by LabWindows/CV], and produced software taking the example of power resource; this scheme meets ATS self--test request, has strong practicability.
