虚拟仪器与传统ATE联合测试技术研究

虚拟仪器技术是测试领域的重要发展方向,在IC测试中也有广泛应用。传统IC测试技术主要基于传统自动化测试系统(ATE),随着IC设计和制造技术的进步,普通IC测试系统已不能满足研究和生产需要。文章介绍了一种利用虚拟仪器技术与传统IC测试系统结合的测试方案。该联合测试系统把传统测试系统、数据采集卡和分立仪器通过LabVIEW程序联合在一起。系统组成包括硬件和软件两部分,其中硬件部分由ATE系统、测试PC和示波器组成,软件使用LabVIEW程序编写,完成仪器控制、数据采集和报表生成等功能。该系统已完成了某型号数模混合电路的测试。

Test Technique Research of Combine Virtual Instrument with ATE

Virtual instrument technology is an important field of test and control. It was also used in IC test. Traditional IC test mostly base on auto test equipment （ATE）. The technology of design and manufacture continuous improve, traditional test systems can not meet the requirement of research and production. The paper introduced a scheme that combines virtual instrument technology and traditional ATE. The test system combined traditional ATE, data acquisition card and independence instrument with LabVIEW software. The system is compose of hardware and software. Hardware system is composed of ATE system, test PC and oscilloscope. Software designed with LabVIEW language. It manage the work like that the machine control, data acquisition and report build. The system is used for test of some digital analog max IC.
