Shrnutí:In this paper, a novel approach to symbolic regression using Kolmogorov–Arnold Networks (KAN) for developing gray-box Simulation Program with Integrated Circuit Emphasis models of generic transistors is proposed. Unlike traditional black-box models, such as artificial neural networks, (ANN), the developed KAN-based model enhances interpretability by generating explicit mathematical expressions while maintaining high accuracy in device modeling. By combining the computational efficiency of neural network approaches with the transparency of formula-based modeling, the SPICE model generation is significantly accelerated, thereby improving the efficiency of the design technology co-optimization (DTCO) process. The experimental results demonstrate that the expressions derived from the KAN model accurately represent the current–voltage (I–V) characteristics of the BSIM–CMG compact model and provide nearly symmetric results. To further validate the effectiveness and versatility of the approach, we embedded the trained I–V KAN model into a 12 nm FinFET SPICE model and performed 11-stage ring oscillator (RO) simulations. The results indicate that the KAN-based SPICE model achieves accuracy comparable to the original 12 nm FinFET SPICE model, demonstrating its potential to streamline device modeling for advanced technology nodes.
