摘　　要：面向信号的测试软件平台是未来自动测试系统发展的趋势,信号的匹配是面向信号软件平台内核需解决的关键问题之一;为满足不同测试阶段、不同测试目标的面向信号自动测试系统设计需求,提出了基于仪器集最小和基于匹配最佳的两种信号匹配算法;并以某ATS工程为实例,验证了算法的有效性及相互关系;结果表明,两种算法所匹配的信号不同,但均可适合于ATS的工程应用,而基于匹配最佳的信号匹配算法可提高测试的准确度。Signal--oriented test is the development trend of next generation automatic test system （ATS）. One of the key problems which needs to be resolved by the kernel of ATS software platform is signal matching. In order to meet design requirement of the signal-- ori- ented ATS in different testing stages and for different testing goals, two signal matching algorithms are proposed. One is the least instrument set algorithm, and the other is the best matching algorithm. The validity and relation of the algorithms are validated by an ATS project. The experimental result shows that different signal can be matched by two matching algorithms, but all suit for engineering applications of ATS. Compared with the least instrument set algorithm, the best matching algorithm can improve the test precision.
