VHDL error at <location>: can't synthesize magnitude comparator for user-defined types


CAUSE: In a VHDL Design File (.vhd) at the specified location, you used a magnitude comparator for a type that you defined. However, Integrated Synthesis cannot synthesize magnitude comparators for user-defined types.
ACTION: Use explicitly defined constants with the magnitude comparator.
