SUMMARY
To design an 8-bit adder, connect two 4-bit adders by linking the carry output of the lower-order adder to the carry input of the higher-order adder. The outputs of both adders combine to form the final 8-bit output. This method ensures accurate addition by managing carry bits effectively. The XOR operation is crucial for handling the addition of binary values.
