XCVLXMB the board Xilinx SRAM_BASED FPGA design is the main element Pieces, SRAM_BASED the FPGA, the design began to verify the results, may experience many changes, this time as long as the JTAG s DOWNLOAD CABLE with the IMPACT software is conti

在设计手动播放和自动播放可以选择使用的电路中，程序在下载完成后，可以实现手动播放和自动播放的按键转换，通过switch按键，当按键处于‘1’状态时。则处于自动播放音乐（两只老虎），当按键‘0’时，处于手动播放音乐。自动播放和手动播放互不干扰，但是可以通过按键进行转换，最终实现实验目的。-In circuit design manual play and auto play can choose to use the program after the download is complete,
