摘　　要：在数字信号处理系统开发中,FPGA的系统级设计工具DSP Builder为多种波形信号发生器的设计提供了一种较为简单的设计方案。根据产生波形的基本原理,在Matlab中完成算法设计,Simulink中完成仿真模型。利用Altera公司提供的Signal Compiler编译工具进行编译,生成能够被QuartusⅡ识别的VHDL代码,使用波形仿真工具Modelsim进行仿真,并通过QuartusⅡ完成对FPGA器件的配置下载过程实现应用仿真。该方案具有设计简单、外围电路少、不需要编程等优点,能够减轻开发者的工作量。In the development of digital signal processing system,the simpler designing solution of Multi-wave signal generator is designed based on DSP Builder.According to the basic principles of signal generator,the basic model algorithm using DSP Builder is established.The algorithm design is completed by Matlab and the simulation is completed through the Simulink Tool.The Signal Compiler tool from the Altera Corporation is used to compile and generate VHDL code that can be recognized by QuartusⅡ.The waveform simulation tool Modelsim is used for simulation.The configuration of the FPGA device is downloaded through QuartusⅡto achieve the simulation application.The results prove that the design is correct and show that the advantages of simple design is simpler,few peripheral circuits and no programming,which can reduce the workload of developers to implement the Multi-wave signal generator.
