ID:13883 VHDL Interface Declaration error at <location>: constant or signal "<name>" in Interface Constant or Signal Declaration cannot be subtype <type> of file type or access type

CAUSE: In an Interface Constant Declaration or Interface Signal Declaration at the specified location in a VHDL Design File (.vhd), you declared the specified interface constant or signal with the specified subtype of a file type or access type. However, the constant or signal cannot have a subtype of a file type or access type.

ACTION: Change the subtype indication for the interface constant or signal so it does not denote a file or access subtype, or change the Interface Constant Declaration or Interface Signal Declaration to an Interface File Declaration.
