基于DSP Builder的电子技术仿真实验平台

Simulation experimental platform for Electronic Technology course based on DSP Builder

为解决电子技术课程学时少、实验量大,学生对系统级通信知识了解少而难于建立模型的问题,提出一种基于DSP Builder的电子技术仿真实验平台的设计方法。以FSK调制器、幅度调制信号发生器和移相信号发生器为例,分别在该仿真实验平台建立模型并利用DSP Builder软件进行系统仿真,最终转换为硬件语言模块下载到硬件中,利用FPGA中的逻辑分析仪再次验证移相信号发生器设计的结果。在算法级系统设计方面,该仿真实验平台易于建立模型,实现简单,有利于学生对电子技术知识的掌握,增强自主学习能力。

In order to solve the problem with short of class hours,a mass of experiment for electronic technology and difficult to build model because of less knowledge of the system level communication to students,a kind of simulation experimental platforms based on DSP Builder/FPGA is proposed.FSK modulator,amplitude modulation signal generator and phase-shift signal generator,which are modeled and emulated,are taken for example.The simulation finally is converted to hardware language modules by DSP Builder software,which is downloaded to the hardware.The simulation results are verified by reusing the logic analyzer of FPGA.Through experimental verification,in terms of algorithm level system design,the simulation platform is easy to be modeled and simple to be achieved.The knowledge of Electronic Technology is easy to be mastered,and the self-learning ability is enhanced for students.
