Simulation and Design of DDS Based on Verilog HDL

摘要

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 refrained. It is very easy to achieve frequency modulation, phase modulation and amplitude modulation with the DDS module. It has more comprehensive and nice practicality.
