基于Multisim软件的波形发生器设计

在Multisim软件环境下,以波形发生器为例,本文介绍了一种针对单片微机仪表的设计手段,这种设计手段采用的Multisim软件可以把原理图绘制、程序编制,实验仿真和印刷电路板图的生成集成在一个设计环境中,不但可以做到边设计边实验,修改调试方便,而且实验采用的是虚拟元器件和测量仪器,实验成本低,实验速度快。按此设计手段,本文设计了波形发生器硬件电路,编制了产生三角波和正弦波的程序,仿真运行的结果达到了设计预期要求。通过该例说明,采用Multisim软件设计单片微机仪表的手段是方便有效的。

Signal generator based on Multisim

Based on Multisim, the paper takes signal generator for example to introduce a method of designing instrument with SCM. Multisim software can integrate some design tools into one single environment, such as plotting, programming, experimentation simulating and circuit board drawing. In the design environment of Multisim, it is convenient to experiment while designing, and easy to modify and debug. Moreover, it costs less as using virtual components and apparatus, but works faster. Based on this, a signal generator is designed. It can produce trigonal wave and sine wave. This example shows it is applicable to design instrument with SCM by Multisim.
