Aim: To design and simulate a 4-bit Ripple Carry Adder using Verilog HDL with a task to implement the full adder functionality and verify its output using a testbench. To design and simulate a 4-bit ...

Three Codes shall be written for implementation of 4-bit Adder as follows, • fa.v → Single Bit 3-Input Full Adder [Sub-Module / Function] • fa_4bit.v → Top Module for Adding 4-bit Inputs. • ...

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.
