It can be hard to see how the carry chain is working in the previous example. n/2 (implemented as three ripple adders of size n/2 along with muxes).

Introduction A full adder adds two 1-bit binary numbers along with 1-bit carry-in thus generating 1-bit sum and 1-bit carry-out.If A and B are two 1-bit values input to the full adder and C in is the carry-in from the preceeding significant bit of the calculation then the sum, S, and the carry-out, C out, can be determined using the following Boolean expressions.

The multiplier accepts two 8-bit numbers multiplicand and multiplier and results in 16-bit multiplication. A Verilog code for a 4-bit Ripple-Carry Adder is provided in this project. Working Of 4-bit Ripple Carry Adder- Let-The two 4-bit numbers are 0101 (A 3 A 2 A 1 A 0) and 1010 (B 3 B 2 B 1 B 0). To proceed with Verilog Code, we shall first understand the structure of the 4-bit Ripple Counter. The proposed design consumes a minimum power of 33.46 µW and offers a minimum propagation delay of 0.04 ns in comparison to state-of-art adders such as ripple carry adder (RCA), carry look ahead. This will use when the addition of two 8 bit binary digits sequence. Normally if you have three numbers, the method would be to add the first two numbers together and then add the result to the third one. These numbers are to be added using a 4-bit ripple carry adder. The 1-bit carry-in input port Cin is used to read in a carry bit, if another instance of the ripple carry adder is cascaded towards lesser significant stage. We are providing a Final year IEEE project solution & Implementation with in short time. An example of a 4-bit adder is shown below which accepts two binary numbers through the signals a and b which are both 4-bits wide. I grabbed the test bench from a 8 bit multiplier to use for the RCA and so I know I am overlooking something. Since an adder is a combinational circuit, it can be modeled in Verilog using a continuous assignment with assign or an always block with a sensitivity list that comprises of all inputs.
