Design an $8-$bit parallel adder using a circuit diagramming software of your

choice $($e$.$g$.$ Logisim or Circuitverse$).$

a$.$ Use the $6-$bit adder to perform the operation $(10100111)2+(11010101)2.$

b$.$ Show the adder and final answer in a single screenshot.

c$.$ You may use adder blocks instead of XOR and AND gates.

d$.$ Keep the final answer to $8$ bits.
