好的，我添加了我的microblaze，从XPS生成了一个topvhdl文件，添加了ucf文件，在我的microblaze中，我有4个GPIO，但我没有把它们的任何引脚放在.ucf文件中，虽然它们在topvhdl中作为inout存在，但我能够编译项目并生成一个比特流。现在，我注释掉了顶级vhdl中的所有GPIO引脚，并将我的microblaze系统GPIO与内部信号连接起来，如图所示，这也没有任何问题，我可以生成比特流。现在引起这个问题的是，当我将7个LED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！代码如下：

这是一个评论，因为我还不被允许发表评论:/

我不确定这个错误是不是失败。我更愿意说，不打印之前的错误消息是一个失败。如果您正在处理某些输入，则应始终注意快捷键。尝试将它们设置为open，这样它们根本不会连接到您的FPGA。
