To test the computation unit, use the inputs $1001$ and $0101$ for the first

test case and $0110$ and $1001$ for the second test case. Calculate the expected values and then record the simulated outputs in a table for comparison

to verify that they match.

To test the overall design, use the following test cases and similarly record

the calculated vs simulated outputs in a separate table for comparison.

Case $1$:

$$ A: $1011,$ B: $1100,$ C: $1001,$ D: $0011$
