这看起来像是电路板的SI问题或电缆的问题。你说早些时候这个工作是相同的板/设备组合吗？你正在使用的具体设备是什么，包括包等...如果你看看
Xilinx安装中该设备的BSDL文件确实IDCODE与iMPACT中的预期匹配，我希望它能。

This looks like a SI issue with the board or a problem with the cable.
You say earlier this worked was this the same Board / device combination?
What is the specific device that you are using, include the package etc.. if you look in the BSDL file for that device in the Xilinx install does the IDCODE match the expected one from iMPACT, i expect it will.
