ID:13039 The following bidirectional pins have no drivers

CAUSE: The design has one or more bidirectional pins that have no driver - that is, they are behaving as input pins. 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 pins as input pins instead of bidirectional pins. See the sub-messages below to view the list of such bidirectional pins.
