基于FPGA的信号发生器设计
摘要：信号发生器在各种实验和测试中是必不可少的器件，同时在生产和科技领域中有着广泛的运用，例如在通信、控制、雷达、教学、军事等领域。本次设计的内容是基于FPGA的信号发生器设计，要求用EAD技术设计一个信号发生器，此信号发生器的实现是利用EDA的硬件描述语言VHDL产生各个模块，然后在Altera公司提供的FPGA/CPLD开发集成环境的Quartus II软件上实现波形的编译、仿真、下载到Cyclone芯片上。信号发生器由波形产生模块、频率调节模块和波形选择模块组成，波形产生模块可以产生三角波、正弦波、方波、阶梯波、递增斜坡、递减斜坡、自定义波形等，通过波形选择模块和频率调节模块可以选择自己所需要的波形和调节一定的频率。

FPGA implementation of signal generator
Abstract:The signal generator is a essential device in various experiments and tests, at the same time, it widely used in the production and technology field, such as communications, controlling, radar, teaching, military and other fields. The content of this design is the signal generator’s implementation of FPGA, it required to design a signal generator with EAD technology, which used EDA’s hardware description language VHDL to produce each modules, and then achieved the compilation, simulation and downloads of the waveform to the Cyclone chip by using Quartus II software on the integrated development environment of FPGA / CPLD which provided bycompany Altera. The signal generator contains the waveform generator module, frequency adjustment module and waveform selection module. The waveform generator module can produce triangular wave, sine wave, square wave, staircase, ascending slope, descending ramp, custom waveforms, etc., and the waveform selection module and the frequency adjustment module can select the waveform in their needs and adjust the certain frequency.
