The design consisted of modular components, utilizing a 1-bit Full Adder as the building block. These Full Adders were cascaded to handle the 4-bit addition, producing a 4-bit sum output and a carry ...

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.

In this work, the parallel prefix adders like Kogge-Stone adder, Brent-Kung adder, Sklansky adder, Ladner-Fischer adder and Han-Carlson adder are used. The circuit is designed in Verilog HDL. The ...
