After the schematic is correctly entered, you will need to simulate the circuit. The simulations will come out as wave forms which are hard to read without detailed study. In laboratory reports, you MUST ANOTATE a representative sample of the 128 cases. See Fig. 22 What is a representative sample? You need to show both additions and subtractions. You need to show both positive and negative numbers. You should show overflows both form (numbers) <-4, and (numbers) > 3. It will be easier if you zoom out enough so the numbers can be seen on the waveforms
