    Precedence: bulk

    Change the third casez item to:
    8'b0001????: instruction3 (ir);

    -----------------------------------------------------------

    Proposal for Errata 190:

    In Example 1 in 9.5.1:

    REPLACE the example code:

        reg [7:0] ir;

        casez (ir)
            8'b1???????: instruction1(ir);
            8'b01??????: instruction2(ir);
            8'b00010???: instruction3(ir);
            8'b000001??: instruction4(ir);
        endcase

    WITH the following modified code:

        reg [7:0] ir;

        casez (ir)
            8'b1???????: instruction1(ir);
            8'b01??????: instruction2(ir);
            8'b0001????: instruction3(ir);
            8'b000001??: instruction4(ir);
        endcase

    NOTE: The only change is to the third case item where the 0 following the 1
    in the case item expression is changed to a ?.
