For 2 inputs -> 4 output line For example, if we need to implement the logic of a full adder, we need a 3:8 decoder and OR gates. The input to the full adder, first and second bits and carry bit, are used as input to the decoder. Let x, y and z represent these three bits. Sum and Carry outputs of a full adder have the following truth tables I'll present a solution based on this, and maybe it will provide some insight to your original problem. Actually, it only requires one additional gate to make them active-high, but I'll leave that as an exercise for the reader. Full adder using 2 to 4 decoders

Due to the important role played by Full adder in various arithmetic units, optimized design of Full adder to achieve low power, small size and delay is needed Design. 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. 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. The code shown below is that of the former approach

Like half adder, a full adder is also a combinational logic circuit, i.e. it does not have any storage element. But due to additional logic gates, it adds the previous carry and generates the complete output. Thus, it is called full adder. A full adder can also be designed using two half adder and one OR gate Full Adder. The half adder is used to add only two numbers. To overcome this problem, the full adder was developed. The full adder is used to add three 1-bit binary numbers A, B, and carry C.

It consist of three input bits that are to be added and two output bits that are sum and carry. The truth table for half adder is: x. y. z. C Full-Adder. The half-adder is extremely useful until you want to add more that one binary digit quantities. The slow way to develop a two binary digit adders would be to make a truth table and reduce it. Then when you decide to make a three binary digit adder, do it again. Then when you decide to make a four digit adder, do it again A full adder can be implemented using two half adders and one two input OR gate. So what is a half adder? A Half adder adds two inputs bits, to give one Sum and one Carry output bit. Half adders have the following truth table and logic circuit
