Claim One:
1. A method for parametrically adapting a behavioral model programmably implemented for emulating signal transfer behavior of an undisclosed circuit in an electronic system to supply reference level fluctuations, the method comprising: establishing a behavioral model pre-configured with respect to a preset supply reference level, the behavioral model including: at least one predefined Current-Voltage (I-V) curve characterizing variations of a modeled current parameter for a portion of the undisclosed circuit responsive to different output voltage values thereof, and at least one corresponding pair of Voltage-time (V-t) curves respectively characterizing variations of a modeled voltage parameter across said portion of the undisclosed circuit responsive to predefined rising and falling transitions in input voltage thereto; and, adaptively scaling the behavioral model for deviation of the electronic system supply reference from said preset supply reference level, said scaling including reconstructing a surrogate device parametrically representative of said portion of the undisclosed circuit, the reconstruction including: pre-setting a transistor type for said surrogate device, said surrogate device being thereby configured with a conductive channel current-voltage characteristic of said preselected transistor type; and, generating a plurality of device-specific properties for said surrogate device based on selective cross-correlation of operating points between said conductive channel current-voltage characteristic and said V-t and I-V curves of the behavioral model; and, selectively replacing an instantaneous value for said modeled current parameter of the behavioral model with a scaled channel current value generated for said surrogate device responsive to the deviation of the supply reference from said preset supply reference level, said scaled channel current value being generated based on said device-specific properties.
