摘要
本文利用FPGA完成波形发生器的设计,可以产生频率和幅值都可调的正弦波和三角波。首先对标准波形进行采样,然后经过D/A转换和滤波输出平滑的波形。采用VHDL硬件描述语言完成波形发生和存储程序编写,并下载到Xilinx公司的SpartanⅡ系列目标芯片XC2S2005PQ-208上调试通过,得到的波形好,可达到技术指标。
The FPGA-based Wave-Generator can generate sine wave and triangle wave. First, it samples the standard wave, and then generates a smooth wave after DA converter and filter. The generator uses hardware design language VHDL to finish the wave generation and storage. The wave is downloaded into the object chip of XC2S2005PQ-208 SpartanⅡ, Series, Xilinx, Co and passed the test, which meets the technique indexes.
