fpga - fpga引脚已停用

我一直在开发IP，在我将其用于项目中之前，它一直运行良好。

之后，fpga的两个输出引脚根本不起作用！经过一番调查后，我才意识到，在设计摘要中，这两个引脚在reg下报告，值为“ java.lang.IllegalArgumentException: Host name may not be null at org.apache.http.HttpHost.<init>(HttpHost.java:79)

任何人都可以告诉我如何切换引脚off和off以及它如何以这种方式工作吗？

这些引脚只需要简单地做一下工作即可，只需转动LED on和on，当我测试IP时，它们工作正常，只是在较大的项目中关闭了。
