SystemC-AMS allows the modeling of complex heterogeneous systems at different levels of abstraction using different modeling styles, called Models of Computation (MoC) [1][2]. This work presents an approach for including energy consumption information in high-level modeling of linear electrical circuits described using the SystemC-AMS Linear Signal Flow (LSF) MoC. The method introduced here proposes to start from a description of the system at a low level of abstraction, which is a description using the SystemC-AMS Electrical Linear Network (ELN) MoC or a SPICE netlist. The following steps of the proposed approach automatically extract the state space representation corresponding to the analyzed circuit. The case study that we present as a proof of the proposed approach is a passive fourth-order low pass filter. In Section 1, we present the state space representation. In the following Sections, we present how it is possible to automatically extract this mathematical model and how the power consumption information can be added to this representation.
