您好：
我使用的是 ADS5295 评估板。 我将 P10 连接器转换为接头、并使用双绞线输入 ALINX AC7020C 卡的引脚。
我想使用 2 线通信、12 位分辨率和 1/4 样本设置。
我从 xapp524 文档 (secure.xilinx.com/.../clickthrough.do) 中的链接下载了该文件 、并在 Vivado 中创建了自定义 IP。 然后我进行了连接并输入了配置。
连接：
ADC IP 配置：
我还在 XDC 文件中指定了我的 PIN 并进行了合成。

但 Bram 的使用率约为 236%。 这是正常的、我在哪里做错了？
如果我能克服这个问题,我会有其他问题:)
