FPGA下载问题

[Yuixz]

为什么有些代码生成网表无误,生成比特流有错误？请求帮助。。

[Yuixz]

ERROR:MapLib:979 - LUT6 symbol "mp_0/mp_0/ipif_IP2Bus_Data<10>33" (output signal=mp_0/mp_0/ipif_IP2Bus_Data<10>33) has input signal "mp_0/mp_0/USER_LOGIC_I/ps/res<53>" which will be trimmed. See Section 5 of the Map Report File for details about why the input signal will become undriven. 这是生成的错误，请帮忙解决。谢谢

好像是PIN Assignment有问题。

对这个不太了解，请问您知道具体的改法吗？

See Section 5 of the Map Report File for details about why the input signal will become undriven. Map Report 里是怎么说的

估计是把电源脚定义为IO了
