In this project, we are going to design a serial adder. A serial adderis a circuit that performs binary addition bit by bit (i.e., insteadof presenting both operands at the inputs of an adder at the sametime, the operands are fed into the serial adder bit by bit andit generates the answer on the fly). To design such a circuit, we aregoing to use the state diagram as the mode of describing thebehavior of the circuit, and then translate the state diagram into Verilogcode.
