基于模型的DDS芯片设计与实现

Model_based design and implementation for DDS chip

介绍了一种基于模型的DDS芯片的设计方法。根据DDS基本原理,在MATLAB环境下建立模型,用System Generator产生VHDL程序,并在ISE软件中编写仿真和控制程序,最后在Spartan-3E Starter Kit开发板上实现设计。与传统的FPGA编程设计方法相比,本文所介绍的方法可以避免繁琐的编程工作、节省时间并降低出错概率。实验结果证明了这种设计方法的可行性。

Introduced one method of designing DDS chip based on model. According to the DDS basic principle, established the model in MATLAB environment, generated the VHDL program by using System Generator, simulinked and designed control program in ISE software, implementation this design on Spartan-3E Starter Kit board. Compare with the traditional FPGA programming design method, the method mentioned in this paper can avod of cumbersome works save developing time and decline possibility of error. Experiment results proved this design method is feasible.
