ID:13936 VHDL attribute warning at <location>: attribute "<name>" cannot be specified for multidimensional port "<name>" -- attribute is valid only for single-bit or one-dimensional ports

CAUSE: In an Attribute Specification at the specified location in a VHDL Design File (.vhd), you attempted to specify an attribute for the specified multidimensional port. However, the attribute is valid for single-bit or one-dimensional ports only.

ACTION: Remove the Attribute Specification, or, if you used ALL or OTHERS in the Attribute Specification, change the Attribute Specification so it specifies the attribute for an entire entity class. Otherwise, if you want to apply the attribute to the port, declare the port with a single-bit or one-dimensional type. Use the message that immediately follows this message to locate the port's Port Declaration.
