VHDL warning at <location>: ignored choice with illegal range bounds


CAUSE: In a VHDL Design File (.vhd) at the specified location, you used a choice that contains range bounds. However, the range bounds are illegal; therefore, Integrated Synthesis ignored the choice.
ACTION: If you do not want Integrated Synthesis to ignore the choice, or to avoid receiving this message in the future, make sure the range bounds in the choice are legal. Otherwise, no action is required.
