Embedded Systems Energy Consumption Analysis Through Co-modelling and Simulation

Abstract—This paper presents a new methodology to study power and energy consumption in mechatronic systems early in the de-velopment process. This new approach makes use of two modeling languages to represent and simulate embedded control software and electromechanical subsystems in the discrete event and continuous time domain respectively within a single co-model. This co-model enables an accurate representation of power and energy consumption and facilitates the analysis and development of both software and electro-mechanical subsystems in parallel. This makes the engineers aware of energy-wise implications of different design alternatives and enables early trade-off analysis from the beginning of the analysis and design activities. Keywords—Energy consumption, embedded systems, model-driven engineering, power awareness. I
