Half Adder Using Data Flow Method
A Half Adder is a basic combinational circuit used in digital electronics for adding two single-bit binary numbers. It produces two outputs:

Sum (S): The XOR of the input bits.
Carry (C): The AND of the input bits.
In the Data Flow Method, we describe the circuit behavior using Boolean equations directly, often written in a Hardware Description Language (HDL) like Verilog or VHDL.

Detailed Description
Inputs:
A: First single-bit binary input.
B: Second single-bit binary input.
Outputs:
Sum (S): The result of the XOR operation between A and B.
Boolean Expression:
𝑆
=
𝐴
⊕
𝐵
S=A⊕B
Carry (C): The result of the AND operation between A and B.
Boolean Expression:
𝐶
=
𝐴
⋅
𝐵
C=A⋅B
Logic Behavior:
The Data Flow Method focuses on the direct representation of these Boolean equations. For example:

assign Sum = A ^ B;
assign Carry = A & B;

module half_adder(
input A, // First input bit
input B, // Second input bit
output Sum, // XOR of A and B
output Carry // AND of A and B
);

// Data flow modeling using Boolean equations
assign Sum = A ^ B; // XOR operation
assign Carry = A & B; // AND operation

endmodule
