You are given a design board with two input pins A and B and three

output pins R$,$ C$.$out and V$.$ Build from gates a $6-$bit signed$-$number

subtractor circuit, which subtracts B from A asserting the difference on

R and the carry$-$out on C$.$out. If subtraction causes a signed$-$number

overflow, your circuit must assert $1$ on V$,$ otherwise V should be low.

You may use $$ and combine $$ any of the circuits you have already

built as the basis for this, but you may not use any of Logisim$$s builtin arithmetic devices to solve this problem. Use the Logisim template

$7$COM$1013.$circ$-$T$02$L$1$e$04.$circ attached as a starting point for your

circuit. A one$-$bit full full adder is provided with the design board for

your convenience.
