摘要
针对数字电路测试中对测试资源管理方法通用性的需求,以测试泛环境ABBET(ABroad BasedEnvi ronmentforTest)资源管理软件接口和IEEE1445标准为基础,采用面向信号的测试资源管理方法,构建了虚拟测试资源模型,论述了虚拟测试资源模型的基本组成.在数字电路测试中,通过使用虚拟测试资源模型来隔离测试软件和硬件设备,使ATS中仪器和信号通道的变化与测试软件的开发及使用没有关联性,从而实现测试软件对仪器访问控制的通用性.以实际电路板为被测对象,对基于虚拟测试资源模型开发的TPS(TestPro gramSet),选取两套不同厂家的数字电路ATE设备作为运行的硬件平台,测试结果表明:TPS可以运行在不同的ATE上,实现了测试资源管理方法的通用性,提高了数字电路TPS的适用性.
Considering the generalization of test resource management in digital circuit test, the virtual test resource model, applying the signal oriented test resource management method and being based on the software interface for resource management for A broad-based environment for test and IEEE1445, was introduced. The signal oriented test resource control interface, the capability description of digital circuit test instrument, the interconnections description of the signal adapter devices, and translating the logic test device′s command to the given physic device′s control command in the model was described. The test software does not depend on the test instruments, the changes of test instruments and signal channels will not affect the development of fault diagnosis software. Take two digital circuit ATE instruments form different manufactories as the running hardware platforms, test program Set (TPS) developed by the model was used to the actual circuit board. It is seen that the TPS can run on the two different platforms, with generalization of test resource management realized and applicability of digital circuit TPS improved.
