波形发生器已成为现代测试领域应用最为广泛的通用仪器之一。本设计主要是利用硬件描述语言VHDL设计一个波形发生器，波形发生器根据设计所设定的初始输入信号，可以输出可选择的频率和幅度波形。正弦波、方波、三角波、阶梯波、锯齿波、递增波、递减波这7种波形信号，是本次设计的主要波形。此次毕业设计使用的工程软件主要是由Altera公司推出的Quartus II软件。 

本次毕业设计主要是使用文本输入程序，新建项目工程，通过设计程序输入、编译调试、仿真调试完成每一种波形的产生以及每部分的调控选择模块的设计。本文中设计将分模块进行，便于每一部分的仿真调试及错误的查找。实验运用硬件描述语言VHDL编写程序，实现各个波形的产生以及频率和幅度的改变，并且通过7选1选择开关的设计，实现了对需要不同波形，不同频率，不同幅度的选择。本次设计所涉及的波形都是基本波形，这些波形在各个领域都会被运用到。为了实验、教学、研究方便，研制一种基本、简单、使用方便的基本信号源是十分必要的。

Abstract Digital electronic technology and Internet computer technology has been widely used in all walks of life, such as medical, education, military and national defense, social life and other fields。 The application of electronic technology design has become the core of the modern society, we call this technology EDA technology。 Hardware description language VHDL is an important part of the technology, the hardware description language VHDL is currently the most popular hardware description language of, the language has good portability, readability and other characteristics, and GF application in electronic design。

Waveform generator has become one of the most widely used instruments in the field of modern testing。 This design mainly uses the hardware description language VHDL to design a waveform generator, the waveform generator according to our set of initial input signal, can output the choice of frequency and amplitude waveform。 Sine wave, Fang Bo, triangle wave, step wave, saw tooth wave, Di Zengbo, descending wave of these 7 kinds of waveform signal, is the design of the main waveform。 The graduation project is designed to use the project software is mainly launched by the Quartus II Altera software。

The design use of text entry program, through the design of input, compile, simulation to complete a variety of waveform signals and the design of various control options。 The design is pided into modules, which is convenient for each part of the simulation debugging and error search。 Experiments using hardware description language VHDL programming, implementation of each waveform and frequency and magnitude of change, and the 7 selected option 1 switch design, realizes the need different waveforms and different frequency, different amplitude selection。 All waveforms involved in this design are the basic waveform, which can be used in various fields。 In order to experiment, teaching and research, it is very necessary to develop a basic signal generator which is simple and easy to use。
