A method for generating high-speed circuit design schemes based on multi-objective optimization

Abstract

This invention discloses a method for generating high-speed circuit design schemes based on multi-objective optimization. This method constructs a feature-performance correlation model coupled with multi-physics fields, combines hard constraint thresholds with a multi-objective optimization algorithm to build an optimization model, and collects dynamic design parameters such as wiring topology, device parasitics, dielectric characteristics, and process deviations in real time to generate an initial design scheme. Then, it monitors performance index deviations and constraint adaptation deviations, dynamically corrects the objective weight coefficients and constraint penalty coefficients in the multi-objective optimization algorithm, and generates an iteratively optimized high-speed circuit design scheme. This invention achieves multi-objective collaborative optimization and adaptive adjustment to process fluctuations through multi-physics field coupling modeling and a dynamic deviation feedback correction mechanism, significantly improving design accuracy, efficiency, robustness, and engineering feasibility.
