ID:10415 VHDL unsupported feature error at <location>: nonobject aliases are not supported

CAUSE: In an Alias Declaration at the specified location in a VHDL Design File (.vhd), you declared a nonobject alias, that is, an alias for a named entity that is not an object. However, Quartus Prime Integrated Synthesis does not support nonobject aliases.

ACTION: Delete the Alias Declaration for the nonobject alias, or change the Alias Declaration so it declares an alias for an object.
