verilog codes

Verilog code for Full Adder in different abstraction levels: A Full Adder is a combinational logic circuit which has three inputs and two outputs. It adds the three binary values and gives two outputs sum and carry . These full adders can be cascaded to form an n-bit ripple adder. It is mainly used in ALU to perform arithmetic operations. The functionality of full adder for different inputs is shown in the below table. a b c sum carry 0 0 0 0 0 0 0 1 1 0 0 1 0 1 0 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 1 1 0 0 1 1 1 1 1 1                                                               Functional table of a full Adder Design/RTL code: Now, let’s see the Verilog code to implement the full adder using different abstraction l
