黑金的教程做的实在太拉闸了，于是自己摸索信号采集模块的使用方法。
ADC模块：AN9238
FPGA开发板：AX7020；Xilinx 公司的 Zynq7000 系列的芯片XC7Z020-2CLG400I，400引脚 FBGA 封装。

ADC的引脚绑定参考开发板J11的引脚信息。
2.ILA在线调试
连接好开发板的JTAG接口，给开发板上电。在HARDWARE MANAGER界面点击“Auto Connect”，自动连接设备。选择 xc7z020_1，右键“Program Device...”。在弹出窗口中点击“Program”。
此时弹出在线调试窗口，出现之前添加的信号：
ILA的状态控制和显示窗口包括：
- 循环采样
- 启动采样
- 无条件执行采样
- 停止采样
