ID:14038 WYSIWYG LCELL COMB primitive "<name>" has LUT_MASK parameter that is dependent on one or more unconnected input ports

CAUSE: The specified WYSIWYG LCELL COMB primitive has a LUT_MASK parameter value that is dependent on one or more unconnected input ports. Either the LUT_MASK parameter value must be simplified so that it is not dependent on unconnected input ports, or all of the input ports it is dependent on must be connected. This message may occur if one or more inputs of the WYSIWYG LCELL primitive is left dangling either directly or after hierarchy flattening.

ACTION: Check your design to make sure all lower level hierarchies are properly connected to the top level. If you are using an EDA tool, contact the technical support for the EDA tool regarding this message.
