ISE综合时报的警告:WARNING:Xst:2677 - Node <DGT8000/INSTRUCTION/ALU_No_BusOut_0> of sequential type is unconnected in block <TOP_PAD>.
程序的意思是在DGT8000 中调用INSTRUCTION ,ALU_NO_BusOut_0是INSTRUCTION的一个端口,在DGT8000中ALU_NO_BusOut_0只是一个WIRE型数据,不输出。WARNING:Xst:2677 - Node <DGT8000/INSTRUCTION/ALU_No_BusOut_0> of sequential type is unconnected in block <TOP_PAD>.
这个警告让我好纠结,前仿真正确,后仿真结果错误,有人曾经遇到过这个警告吗?
