两种EDA设计数据共性剖析与转换

Commonness and Analysis of the Design Data of Two EDA Files

针对异构EDA设计数据阻碍PCB元件组装模拟仿真技术实现的问题,以Protel与PowerPCB为例,分析了其物理参数的存储格式,证明了异构EDA设计文件数据存储存在共性,且可转换成统一格式,设计了异构EDA转换接口,解除了这一障碍,实现了以异构文件作为仿真驱动的关键技术.

This paper contraposes the problem that the design data of the heterogeneous EDA files baffle the implement of simulation of the PCB components serial production. Analyzing the examples of the storing format of the physical parameters in Protel documents and PowerPCB documents, it proves that the commonness which could be transformed into the uniform format exists in the storing format of the heterogeneous EDA documents. It designs the interface of transforming between heterogeneous EDA documents, relieves the impediment and realizes the key technology that makes the heterogeneous documents as the driver of the simulation.
