Half adder is a combinational circuit that performs simple addition of two binary numbers. The input variables designate the augend and addend bits; the output variables produce the sum and carry. It ...

To get better understanding, both the combinational as well sequential circuit has been implemented. Then, by using the concept of digital logic design circuits of half adder and full adder have been ...

The first is a two-bit adder circuit that shows a binary sum and carry on two of the board’s five LEDs. This is a simple combinatorial circuit. It doesn’t make use of the onboard 12MHz clock.

This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx.
