High-level modeling of power consumption in active linear analog circuits

Abstract

This work presents an approach for including energy consumption information in high-level modeling of active linear electrical circuits. The method introduced here proposes to start from a description of the system at a high-level of abstraction (transfer function or state space model) and refine it in order to generate the electrical circuit corresponding, in the form of a SPICE netlist, for example. The following steps of the proposed approach automatically extract the state space representation corresponding to this circuit. During the state space representation extraction, the information needed to find the power consumption is regarded as an output of the state space model. These outputs allow an instantaneous monitoring of the power consumption of the system at a high-level of abstraction. SystemC AMS has been used to model and simulate the examples presented in this paper.
