Optimizing VLSI Layouts through Genetic Algorithm: A Path to Automated Physical Design

This paper presents a Genetic Algorithm (GA)-based approach for optimizing VLSI layouts to advance automation in physical design. Traditional VLSI design techniques often face challenges with complex discrete optimization problems, resulting in inefficient layouts and extended design cycles. The proposed methodology utilizes a binary slicing-tree representation to model module placement and routing, integrated with hybrid pipelining and hardware/software co-design to enhance performance. Mutation and crossover operations are strategically applied to minimize wire length and layout area while improving routing efficiency. Experimental evaluations on industry-standard benchmarks demonstrate that the proposed GA-based layout optimization significantly enhances efficiency and throughput compared to conventional methods. The results affirm that Genetic Algorithms provide a promising pathway toward automated, intelligent, and high-performance VLSI physical design.
