DDS生成正弦波和方波,其中正弦波调用rom的ip核进行查表产生波形,方波直接用计数器counter生成。时钟通过PLL ip核进行分频。使用中注意我的是quartus15.1,别的版本打开文件可能要重建IP核,其中ROM对应的.v文件中的数据文件的绝对地址要改,改成你的就行。
DDS generates sine wave and Fang Bo, where the sine wave calls the IP core of ROM to look up the table to generate waveform, and the square wave is generated directly by counter counter. The clock is divided by the PLL IP core. In the use of my attention is quartus15.1, other versions of the open file may be to rebuild the IP core, of which the ROM corresponding to the.V file of the absolute address of the data file to change to your right.
