说明：  歌曲是什么名字我忘了，代码仅提供一个用verilog编写音乐的模板，想编写什么音乐就往里边套用格式就行了。 本程序无法用软件实现仿真音乐效果，当然可以仿真波形输出，真实音乐效果需用开发板仿真才行，所以就不附仿真图了 用quartus2软件打开即可。
(What are the names of songs I forgot, the code with verilog only prepared to provide a template for the music, what music would like to prepare to apply往里边format will do. This procedure can not use simulation software to achieve the effect of music, of course, can be simulated waveform output, the real music simulation results need to do development board, it is not attached to the use map quartus2 simulation software can open.)
