自适应元器件物理参数库的研究与开发

Study and Development of an Adaptive Component Physical Parameter Database

针对传统数据库的手工逐条录入方式不利于物理参数库快速扩充的问题,本文通过设计一异构EDA转换接口,将格式不同的设计文件转换为格式统一的中间文件,接着在读取分析中间文件内容的基础上,根据用户指定的同名器件添加方式快速完成元器件的自动非重复添加,由此开发了一个独立于EDA设计环境的自适应元器件物理参数库。

In the case of the problem that the manual one-by-one entry method for traditional database is useless for rapid expansion of the physical parameter database, a heterogeneous EDA conversion interface, which can convert the design documents with different formats to intermediary file with unified format, is designed. And then the intermediary file is read and analyzed, following which the component automatic and nonrepetition addition is quickly achieved in accord with the userspecified add method of components with the same name, thus an adaptive component physical parameter database ,which is independent of the EDA design environment , is developed in the paper.
