16-Bit Carry Look-Ahead Adder Design with Cadence Tools

Project Code :TVMABE274

Objective

The primary objective is to design and implement a high-performance 16-bit carry look-ahead adder using Cadence electronic design automation (EDA) tools 4. This adder is designed to efficiently perform binary addition operations on 16-bit numbers.

Abstract

The primary goal of modern communication technology is to develop highly organized architectures that enable high-speed computation with low power consumption. The Carry Look Ahead Adder (CLA) is particularly efficient because it minimizes carry propagation delay, resulting in significant time savings.

In our project, a 4-bit Carry Look Ahead Adder is implemented using the Cadence tool. The logical equations for carry generation (G) and carry propagation (P) are derived to compute the carry and sum for a 1-bit adder. A single-bit carry circuit is designed using the Virtuoso schematic editor. Subsequently, a new cell view for the carry block is created and used as input for implementing the adder.

The design is then scaled up, starting with a 4-bit adder, which forms the basis for constructing 8-bit and 16-bit adders using the Cadence tool.

NOTE: Without the concern of our team, please don't submit to the college. This Abstract varies based on student requirements.
