Pretreatment in Automatic Checking of Schematic Design

For the differences among schematics which have been designed with different electronic design automatic (EDA) tools, a kind of interface file system based on certain checking rules is proposed and designed in this paper. Checking designed data of schematics automatically and heterogeneously will come true by converting different schematics to the interface file. The conversion process is called pretreatment. In addition, this paper analyzes schematic files which have been designed with three kinds of different EDA tools, and will show the process of the pretreatment of Protel schematic file as an example.
