ID:10330 SystemVerilog Enumeration Type Declaration error at <location>: unassigned enumeration element "<name>" cannot follow an enumeration element with an 'x' or 'z' assignment

CAUSE: In a enumeration data type declaration at the specified location in a Verilog Design File (.v), you did not assign an explicit encoded value to the specified enumeration element. Normally, Integrated Synthesis automatically increment the encoded value assigned to the preceding enumeration element. However, Integrated Synthesis cannot increment the encoded value because it has an 'x' or 'z'.

ACTION: Assign an explicit encoded value to the specified enumeration element, or assign a 2-state encoded value to the preceding enumeration element.
