Abstract

The growing complexity of Very Large Scale Integration (VLSI) circuit designs has significantly increased the demand for innovative approaches to enhance design efficiency and fabrication accuracy. Traditional computational methods face limitations in terms of scalability and optimization for complex VLSI systems. The advent of quantum computing presents a promising paradigm shift, offering exponential speedup in solving computationally intensive problems such as optimization, simulation, and data analysis in VLSI design and fabrication. This research investigates the potential of quantum computing algorithms to optimize VLSI circuit design and fabrication processes, addressing key challenges such as layout optimization, routing, and process variation. The problem lies in the increasing complexity and size of VLSI circuits, which often lead to inefficient designs, longer manufacturing times, and increased cost. Current methods such as classical algorithms and heuristic techniques struggle to achieve optimal solutions within reasonable time frames. Quantum algorithms, particularly those based on quantum annealing and variational quantum eigensolvers (VQE), have shown promise in solving combinatorial optimization problems with much higher efficiency. By leveraging quantum computing, the goal is to improve the optimization of circuit layouts, minimize power consumption, and reduce production costs in VLSI systems. The proposed method utilizes quantum computing techniques to model and solve optimization problems related to VLSI circuit design and fabrication. Simulations and comparisons with classical methods show significant improvements in design efficiency, reduced error rates, and faster optimization cycles. The outcomes of this study could transform the future of VLSI design and fabrication, leading to more efficient, cost-effective, and scalable solutions for semiconductor manufacturing.
