In the first pass of the design, we will build a 1-bit full adder (or (3,2) counter) slice that will be used to build the full 4-bit adder. In the second pass of the design, we are going to build the circuit using the IEEE std_logic unsigned package, a much more code efficient and scalable design. In addition, a VHDL issue related to "longest static prefix" is encountered due to the drive of outputs by loop in the process and outputs (numberOfInputs) outside the process. The result is that outputs (numberOfInputs) has a driver as 'U' from the process and a driver as Couts (numberOfInputs) outside the process.

It adds three 1-bit numbers; the third bit is the carry bit. If a carry generates on the addition of the first two bits, the full adder considers it too.
