数字系统逻辑图图形输入系统

A Graphic Input System of Digital System Logic Diagram

本文介绍了一个用于输入数字系统逻辑图连接关系的图形输入系统。利用本系统,用户可以在PC机屏幕上画出逻辑图,与此同时,计算机自动识别出逻辑图中各器件之间的连接关系,并生成一个存贮连接关系的数据文件,供其它系统(如功能模拟系统和自动布线系统等)使用。本系统的特点是,软、硬件支持环境简单,使用方便、灵活、快速、有效。

This paper presents a graphic input system, which is used for inputing the interconnection of digital system logic diagram. With this input system, the user can draw logic diagram on a personal computer screen. At the same time, the computer recognizes the interconnection of components automatically, and stores it in data file which is to be used for other system. The main features of this system are simple in support surrounding of software and hardware, convenient to use, high speed fast—operated and highly effective.
