ID:288012 Output port "<name>" cannot connect to "<text>", which is not a net

CAUSE: In a Module Instantiation port connection in the WYSIWYG primitive to the specified expression. However, the expression is not a net (that is, it does not represent a pin or wire). You must connect the output port to a scalar net, a constant bit-select or part-select of a vector net, or a concatenation of these items. This error may also have occurred if you created or edited a VQM File manually.

ACTION: Make sure the output port connects only to a scalar net, a constant bit-select or part-select of a vector net, or a concatenation of these items. In general, it is better to correct the source design file rather than the VQM File, and then regenerate the VQM File. If the error persists, contact the EDA tool vendor support for more information.
