(a) Design a full subtractor cicuit with three inouts x, y,Bin, and two outputs D and Bout. The circuit subtracts x - y - Bin.Bout is 0 if no borrow is needed to complete the subtraction, and 1if a borrow is needed.
(b) Draw a block diagram showing how four full subtractors canbe used to implement a 4-bit subtraction.
(c) Write a Verilog dataflow model to implement the circuitfrom Part (b).
