| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Accuracy of circuit simulation highly relys on two techniques: compact modeling and parameter extraction. As increasing the complexity of the compact model and the number of model parameters, the parameter extraction is becoming a time-consuming step. In this paper, we propose an automatic environment of automatic-differentiation-based parameter extraction. While the automatic differentiation enables us to accerelate the parameter extraction, the model equation needs to be represented by a calculation graph. The proposed environment automatically generates the calculation graph of the given compact model, and conducts the parameter extraction based on the gradient method. Through experiments using a surface potential model which represents physical behavior of the MOSFET, we demonstrate that our environment achieved 7.94x speedup with preserving the fitting error compared to the numerical-differentiation-based parameter extraction. | |
