You have a typo in your equals logic for the 2-bit comparator. The first term is using ~A1 when it should be ~B1.

    Not sure how to rephrase it any clearer. Your Equal logic assignment should be:

    assign Equal = (~A1)&(~A0)&(~B1)&(~B0)....etc.

      I made correction in code as you said and now more output are correct but 2-3 are wrong still.

      Please Guide me.
