好的，所以我从 XPS 添加了我的 microblaze，生成了一个 topvhdl 文件，添加了 ucf 文件，在我的 microblaze 中我有 4 个 GPIO，但我没有在 .ucf 文件中放置任何引脚，尽管它们在 topvhdl 中作为 inout 存在，但我能够编译项目并生成比特流。现在我注释掉顶部 vhdl 中的所有 GPIO 引脚，并将我的 microblaze 系统 GPIO 与内部信号连接，如图所示。这也没有遇到任何问题，我可以生成一个比特流。现在导致问题的原因是当我将 LED 的 7 个端口添加到我的顶级 vhdl 文件的外部引脚（这与我的 GPIO 无关）时，它开始告诉我 GPIO 引脚上的错误！！！这是代码：

这是一条评论，因为我还不能发表评论：/

我不确定，如果错误是失败的。我宁愿说之前不打印错误消息是失败的。如果您正在处理一些输入，您应该始终注意快捷方式。尝试将它们设置为open，因此它们根本不会连接到您的 FPGA。
