通用成套电子工程CAD系统

A GENERAL INTEGRAT ED CAD SYSTEM FOR ELECTRONIC ENGINEERING

本文介绍了一个通用集成化PCB工程CAD系统。该系统由元件符号、器件符号和元件字典库支持,从电气逻辑原理图设计,自动生成连线表,实现门自动分配,反填逻辑图,交互/优化自动布局,自动/交互布线,到最后输出成套工程图纸及清单报表。能布单层或多层板。适用于电视机、录音机、通讯广播、计算机和自动化仪器仪表等设备。

A general integrated CAD system for PCB is proposed, which is supported by component symbol, device symbol and component dictionary. Its functions in elude electric logic scheme design, creating net-list automatically, gates assignment, reverse-filling logic graph, interactive/automatic placement and routing, and output sets of engineering drawings.
