ID:14807 Bidirectional pin "<name>" has no driver

CAUSE: The specified bidirectional pin has no driver - that is, it is behaving as an input pin. For example, the following Verilog design gives this warning for the pin bidir:
	module test2 (inout bidir, output out); 
	assign out = bidir; 
	endmodule 

ACTION: Declare the pin as an input pin instead of a bidirectional pin.
