Use Verilog HDL code
Coding Exercise 1: Design a 4-bit Adder/Subtractor like the figure seen below. You are to design the adders using user-defined primitives while the rest of the components are using the structural modeling. The \( S \) input switches between the adder and subtractor; if \( S=1 \), then the circuit is a subtractor else it will function as an adder. Figure \( 6.13 \) shows a diagram of the 4-bit Adder/Subtractor circuit.:
