Abstract
A method and system are provided for parametrically adapting a behavioral model pre-configured for a preset supply reference level to fluctuations therein. The behavioral model is adaptively scaled for deviation of the electronic system supply reference from its preset level. The scaling includes reconstructing a surrogate device parametrically representative of a portion of the behavioral model's undisclosed circuit. The reconstruction includes pre-setting a transistor type for the surrogate device, such that the surrogate device is configured with a conductive channel current-voltage characteristic of the preselected transistor type. Device-specific properties for the surrogate device are generated based on selective cross-correlation of operating points between the conductive channel current-voltage characteristic and V-t and I-V curves associated with the behavioral model. An instantaneous value for a modeled current parameter may then be replaced with a scaled channel current value generated for the surrogate device responsive to supply reference deviation from its preset level.
