数字电路虚拟实验的建模与仿真

Model-building and Simulation of the Virtual Experimental in Digital Circuit

为解决一般单位教学必须的实验设备不齐全的问题,对数字电路课程的虚拟实验系统进行了分析与设计,运用数学模型、VHDL文本编辑、图形建模仿真等方法实现了数字电路的虚拟实验,实现了可设计性、操作的任意性和具有真实感的功能,为学生提供了逼真的、不受时间、地域限制的虚拟空间实验平台,自己动手编程、调试、运行程序、模拟仿真结果。

In order to solve the problem that facihties required in education in some units are incomplete, this paper analyzes and designs the virtual experiment system in digital circuit course,and realizes the virtual experiment of digital circuit with math model, VHDL text editing, graphic medeling simulation, etc., providing the designable characteristics, randomicity of operation as well as reality of interactive functions, which provides the learners with virtual space experiment platform that is real, and time limitless and place limitless, and is permitted to program, debug and run program and emulate the simulated results by yourself.
