使用VIVADO编译代码时,其中一个IP报错,错误类似为

Implementation
Opt Design
[Opt 31-67] Problem: A LUT2 cell in the design is missing a connection on input pin I0, which is used by the LUT equation. This pin has either been left unconnected in the design or the connection was removed due to the trimming of unused logic. The LUT cell name is: Inst_XAUI_10Gbe/U0/xaui_0_core/xaui_inst/transmitter/recoder/txd_out[62]_i_3.

这是因为添加IP核时选择了OOC(Out of context)导致的。

在添加IP时编译时,选择Global即可解决问题。
