摘要: 介绍了VCD(Value Change Dump)和WGL(Waveform Generation Language)波形描述文件在集成电路领域的重要应用,并对VCD和WGL文件中的组成元素进行了全面的分析。结合波形文件特点,采用逐行解析匹配关键字的策略对文件进行解析,引入配置文件控制数据处理过程,将波形文件转换为自动测试机台(ATE)所需的测试向量,在Linux环境下采用C/C++语言实现。实际应用表明,该方法转换过程简便高效,在保证测试向量功能正常的条件下,VCD文件和WGL文件的转换时间都有明显缩减,达到了提高转换效率的目的。

Abstract: The important applications of VCD (value change dump) and WGL (waveform generation language) waveform description files in the field of integrated circuits are introduced, and a comprehensive analysis of the elements in VCD and WGL files is conducted. Based on the characteristics of waveform files, a strategy of line-by-line parsing and keyword matching is adopted to parse the files. A configuration file is introduced to control the data processing process, converting waveform files into test vectors required by automatic test equipment (ATE). The implementation is carried out in a Linux environment using the C/C++ programming language. Practical applications show that this method is simple and efficient, the conversion time of VCD and WGL files is significantly reduced respectively while ensuring the normal functioning of the test vectors, achieving the goal of improving conversion efficiency.
