implicit wire has no fan in

It means one of your inputs was connected to dummy wire .
the dummy wire was not connected to any wire .
Pls , check the port connection carefully .
In your wave viewer you can find the dummy wirehava high " Z " value all time .

implicit wire has no fanin

I think the problem is the wire has no driver to drive it.
