摘　　要：根据传统型任意波形信号发生器和基于DDS任意波形信号发生器的设计原理,采用Matlab/DSP Builder的建模方法,在DSP Builder平台上完成两种原理的系统建模和仿真,并用SignalCompiler工具对模型进行编译,产生QuartusⅡ能够识别的VHDL源程序,并通过FPGA芯片EP2C8Q208C来实现,最后用SignalTapⅡ进行硬件测试。经系统仿真和硬件测试,证明两种设计方法的正确性。比较传统的硬件描述语言建模,该方法设计简单、修改方便、成本低、不涉及到任何编程,对硬件理论知识要求不高,实现起来容易。According to the principles of the traditional arbitrary waveform signal generator and DDS-based arbitrary waveform signal generator, the system modeling and simulation of the two principles were achieved with modeling method of Matlab/DSP Builder in DSP Builder platform. Signalcompiler tool was used to compile the models and to generate VHDL source program which Quartus Ⅱ can distinguish. It is realized by FPGA chip EP2C8Q208C. The system simulation and hard-ware testing proved the correctness of the two methods. In comparison with the traditional hardware description language modeling, this method has the advantages of simple design, convenient modification and low cost, does not involve any programming, has not high requirement to hardware theory knowledge, and is easy to realize.
