模拟测试交换格式的研究与实现

Research and Implementation for Analog Test Interchange Format

为提高自动测试系统对模拟电路故障诊断的效率和水平,研究定义一种模拟电路测试交换机制,为基于模拟仿真测试程序集(TPS)开发和数据的传递提供信息和数据格式;通过Spice对电路进行仿真,将仿真数据进行小波分析提取特征,并由BPN、SVM、AIS进行知识生成与评价,最终实现ATIF文件自动生成;实验将ATIF文件解析导入到后处理环境中由测试程序执行检测故障,验证了测试格式的有效性。

In order to improve the efficiency and level of automatic testing systems in analog circuit fault diagnosis, study and defines an analog circuit testing exchange mechanism for Simulation- based test program set development and data transmission provide information and data formats. By Pspice simulation of the circuit and using wavelet analysis to extract features, by BPN, SVM, AIS for knowledge genera-tion and evaluation and ultimately ATIF file is automatically generated. In the experiment ATIF file will be parsed into the post-processing environment, fault detection performed by the TP and reasoning to verify the validity of the test format.
