Application of Compiler Technology in Boundary Scan

摘要:

根据研究对象BSDL文件以及Protel网表文件自身结构特点,运用flex与bison实现词法分析、语法分析及信息储存等阶段,构成一种优秀编译器,对目标文件进行全面、快速、准确地解析；预编译阶段采用正则表达式,将目标文件的信息提取、划分,存入逻辑关系清晰具有层次属性的关系型数据库,节省再次编译时间,有效提高应用效率；测试结果表明,该编译器不但可以准确、全面、快速提取编译信息,而且具有设计简单精巧、容易维护、功能强大等优点。

Abstract:

According to the structural characteristics of BSDL file and Protel netlist file. Use of flex and bison to achieve lexical analysis, syntax analysis, information storage and so on and constitutes an excellent compiler. It is comprehensive, rapid and accurate that analytical target file. Precompiled stage using regular expressions to extract the information of the target file and stored in the database. Avoid build again to save compilation time and improve application efficiency. Test results show that it can extract the information quickly and accurately, it has the advantages that easy to design maintain and powerful function.
