II$.$ Create and simulate a five bit adder

Interconnect five instantiations of ADDsss from I to create a five$-$bit adder and name it AD$5$ss$.$ For simulating$/$testing purposes, consider the numbers as signed and use the four cases shown in the following table. Fill in the range for the $5$ bits. $($connect Cin to $0)$ Do this in one simulation, not four!

$\backslash$table$[[$Operation$,$Results$],[,\backslash$table$[[$Expected$],[$Answer$],[($Dec$.)]],\backslash$table$[[$Test$],[$Result$],[($Binary$)]]],[4+6,,],[-8+5,,],[-8+8,,],[-4+(-8),,]]$

III. Create and Simulate a $5-$bit adder$/$subtractor

Using AD$5$sss from II$,$ add the necessary XORs, and inverter$($s$)$ to create a $5-$bit adder$/$subtractor called ASsss, which you will then test. Hint: see section $5\mathrm{.}3\mathrm{.}3$ in the Brown$/$Vranesic text. You will need to add at least one simple gate to make sure your design is consistent with the Block Diagram and function table below:

Do not try to simulate all possible input combinations for ADDSUB $($there would be $2^9=512$ possibilities!$)$ but use the six operations exactly as shown in the table below. Also, include the completed table in your report. Showing the hex values, all six cases must be in one simulation $($NOT spread out over six different simulations$)$ on only one page. Perform the operations exactly as indicated; e$.$g$.,$ the second operation is plus $3$ minus negative $4.$
