摘　　要：设计了一种基于SOPC的SPWM波形产生电路.在Quartus II 9.0环境下,采用Verilog HDL和模块化的设计方法设计完成.所选FPGA型号为Cyclone系列EP1C2Q240C8.根据不规则采样法产生SPWM波的原理,利用正弦波和三角波实时交叠获取周期可调的SPWM波.仿真结果表明所设计的SPWM发生器IP核能够嵌入专用处理器,实现SPWM器件的驱动.A waveform circuit of SPWM based on SOPC is designed. In Quartus II 9.0 en- vironment, Using Verilog HDL and module design method the design is completed. The select- ed FPGA model is EP1C2Q240C8 in Cyclone series. According to the principle of sinudoidal PWM by irregular sampling, using the real-time overlapping of sine wave and triangular wave, the periodic adjustable SPWM wave is achieved. The results of simulation show that SPWM generator IP core could be embedded in special processor, and realize the driving of SPWM components.
