I am designing 4-bit comparator using 2-bit comparator and made a circuit .
After running RTL stimulation Error occurs.
I don't know why this error occurs as most of the output is correct but few are wrong.
I attached the screenshot of 2-bit comparator code and the circuit diagram of 4-bit if you find something wrong then please guide me regarding that issue.

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.
