基于Verilog HDL的信号发生器的设计

摘要

In order to design the signal generator which can generate four kinds of signals-the sine wave, the square wave,the triangle wave and the sawtooth wave,and whose amplitudes and frequencies are adaptively changeable,a research about works was developed. The design is realized with Verilog HDL in the environment of Altera's Quartus II. When the program was downloaded to the chip of FPGA,the results of the experiments met the scheme design. With Verilog HDL, the design efficiency is improved and the design has the advantages of facility design, convenient operation, high reliability.%旨在研究设计一种可以产生正弦波、方波、三角波和锯齿波等四种波形,且输出波形的幅值、频率可调的信号发生器.在Altera公司的QuartusⅡ工具软件环境下,应用Verilog HDL语言完成了系统的设计,建立的程序工程下载至FPGA器件后,系统实验测试结果达到了预想效果.采用Verilog HDL语言编程来完成整个设计,不但提高了设计效率,而且使系统具有设计灵活、实现简单、性能稳定的特点.
