本文介绍一个实用的人机交互式印刷电路板布线系统。该系统侧重解决模似电路元件构成的单面印刷电路板布线问题。系统不仅可以设计出直接用于制版的印刷电路板版图,还可以给出标有元件图形、汉字、符号的套色元件装配图,并且可以绘出电路原理图。根据所绘电路原理图还可以自动提取元件明细表、电路连接关系表,电路基本描述文件等。 This article describes a practical human-computer interactive printed circuit board routing system. The system focuses on solving the problem of single-sided printed circuit board wiring composed of analog circuit components. The system can not only design a printed circuit board layout directly used for plate making, but also provide a color drawing assembly drawing marked with component graphics, Chinese characters and symbols, and can draw circuit schematics. According to the circuit diagram drawn can also automatically extract the parts list, the circuit connection table, the basic circuit description file.
