In high-speed circuit systems, signal integrity directly impacts data transmission stability and electromagnetic compatibility. To address complex issues such as trace delays, crosstalk, and impedance mismatch, this study introduces a multi-objective optimization method for systematic modeling and solving in PCB design. By establishing comprehensive evaluation metrics that encompass delay, reflection coefficient, and crosstalk suppression, combined with intelligent optimization algorithms to explore design spaces, the method achieves global optimization of design variables. This approach effectively balances signal quality with routing complexity, enhancing high-speed signal transmission reliability while reducing design iteration costs. It provides an efficient design pathway for high-performance circuit systems.
