US 5,349,539 A · Behavioral model parameter extractor

Abstract

An electronic circuit parameter extraction system is provided with a pulse signal forcing generator, an interface to a device under test (DUT), a signal digitizer, a timebase to control the digitizing interval, a data processor to extract DUT essential root parameters, a circuit and/or system simulator to generate signals from the extracted parameters, and a display system to view acquired and/or simulated signals, and is able to compare simulated signals with previously acquired signals. The circuit parameter extraction system further allows extraction of realistic behavioral model parameters which may be used as a component library model within a computer aided engineering (CAE) simulator, allowing improved convergence between the results obtained with the CAE simulator and the physical circuit system response being modeled.
