CAUSE: | In a VHDL Design File (.vhd) at the specified location, you used an enumerated type with the specified character. However, Integrated Synthesis does not recognize the character. As a result, Integrated Synthesis used X for the character. |
ACTION: | If you do not want Integrated Synthesis to use X for the unrecognized character, or to avoid receiving this message in the future, use only recognizable characters in the enumerated type. Otherwise, no action is required. |
