摘要
详细阐述利用QuartusⅡ实现DDS(直接数字频率合成器)模块的方法和步骤。首先分析DDS的设计原理,并对其进行系统建模,利用Verilog HDL实现设计并在开发环境下进行功能仿真,选用现场可编程器件FPGA作为目标器件,得到可以重构的IP核,其可以很方便地实现复杂的调频、调相和调幅功能。利用该方法实现的DDS模块具有更广泛的实际意义和更良好的实用性。
The method and steps of realization of DDS（Direct Digital Synthesizer）on Quartus Ⅱ is described in detail. This paper analyzes the principle of DDS,builds up a system model, realizes DDS module based on Verilog HDL and simulates it. The IP nucleus of DDS which is built can be reframed. It is very easy to achieve frequency modulation, phase modulation and amplitude modulation with the DDS module. It has more comprehensive and nice practicality.
