Abstract: A system and method are provided for generating a programmably implemented model which emulates a power delivery network serving an integrated circuit (IC) core in an electronic system. The system and method generally comprise measures for establishing a power integrity (PI) topology including models for a voltage regulator module that generates at least one predetermined supply voltage level, and for a conductive power rail portion of the power delivery network (PDN). The system and method further comprise measures for interconnecting to the conductive power rail portion model a first behavioral model indicative of the current consumption characteristics of the IC core, and a second behavioral model indicative of the current consumption of an IO interface buffer driving an output signal of the electronic system.

Abstract: A model library contains one or more storable models of a physical system each constructed by numerically solving relationships between a characteristic of the physical system given a set of model parameters. Such a model may be retrieved from the library according to values assigned to the model parameters and used to determine a corresponding characteristic of the physical system without repeating the numerical solution method originally used to create the model. Instead, a mapping may be applied to the storable model to seamlessly obtain the characteristic upon request.

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.
