Objective

The primary goal is to create a 16-bit carry look-ahead adder, which is a type of high-speed digital adder architecture. This design aims to achieve fast addition operations.

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.
