摘要
介绍了DDS(直接数字合成)信号源的原理及组成,给出了VHDL(甚高速集成电路硬件描述语言)源代码,并探讨了在设计中应注意的事项。文中介绍的设计方法和代码已经过实验验证。采用VHDL在FPGA(现场可编程门阵列)器件上完成数字系统的设计,可以大大简化设计过程,提高设计效率,并可以根据实际要求进行灵活修改,充分显示了EDA(电子设计自动化)技术的特点与优势。
The paper introduces design procedures of DDS signal source based on FPGA component, and introduces the principle and the constitution of DDS signal source, and gives a VHDL source code which have been validated and the items which should pay attention to in design process. Adopting hardware describe language to design digital system on FPGA component, can facilitate the designing process and improve the design efficiency greatly.
