A Software Framework for Automated Behavioral Modeling of Electronic Devices

A unified and automated modeling framework is presented that can assist an electronic design automation (EDA) domain expert in generating accurate behavioral models. The framework is a SUMO Toolbox, a flexible tool that integrates different modeling approaches and implements an adaptive behavioral model construction algorithm based on the flowchart. On the modeling side, the model generation process takes full advantage of multicore CPUs if the MATLAB Parallel Computing Toolbox is available, and even of a complete cluster or grid if the MATLAB Distributed Scheduler is available. The performance of the framework is demonstrated with the help of two EM device modeling problems, a passive component and an active device. Results show that ANN model generation code is able to reduce the true error evaluated over a dense reference grid quite effectively while minimizing the estimated error. Obtaining the required circuit design parameters can be done through an approximation of the circuit performance figures based on one or more behavioral models.
