“…There are also approaches in MDD to model software applications and hardware aspects of embedded systems for a power consumption estimation based on UML and MARTE. In [54] and follow-up work [55], an approach for energy-aware scheduling and timing analysis of software applications is presented. The concept is similar for both approaches and is based on a timing-energy analysis model obtained by reverse engineering processes of existing source code resulting in UML class representations.…”

Power consumption has become a major design constraint, especially for battery-powered embedded systems. However, the impact of software applications is typically considered in later phases, where both software and hardware parts are close to their finalization. Power-related issues must be detected in early stages to keep the development costs low, satisfy time-to-market, and avoid cost-intensive redesign loops. Moreover, the variety of hardware components, architectures, and communication interfaces make the development of embedded software more challenging. To manage the complexity of software applications, approaches such as model-driven development (MDD) may be used. This article proposes a power-estimation approach in MDD for software application models in early development phases. A unified modeling language (UML) profile is introduced to model power-related properties of hardware components. To determine the impact of software applications, we defined two analysis methods using simulation data and a novel in-the-loop concept. Both methods may be applied at different development stages to determine an energy trace, describing the energy-related behavior of the system. A novel definition of energy bugs is provided to describe power-related misbehavior. We apply our approach to a sensor node example, demonstrate an energy bug detection, and compare the runtime and accuracy of the analysis methods.

Thanks to CAPES for the financial support during my sandwich Ph.D. studies in Germany. I would like to thank the Carl von Ossietzky University Oldenburg and the University of Applied Sciences Hamm/Lippstadt for the support provided that aided in the accomplishment of my Ph.D. studies. Considering the period I lived in Germany, all the enriching experiences I have had and the lessons learned, I would like to express my gratitude to André Faria, Charles Steinmetz, Cíntia Faria, Edenilda Brachtendorf, Filiz Polat, Renata Lutkehaus and Vincent Marnier. Thank you for dedicating your time, care, friendship and words of encouragement and support over the points of this journey. Finally, I want to thank my mother, Luzia de Fátima Gonçalves, and my daughter, Maria Fernanda Gonçalves. You are the ones who deserve all the honors and are to whom I dedicate all the results and jubilation that come from this research. I know how hard this period was for you both: many absences, relinquishment, days without dialogue and several "rainy days". Thanks for the true friendship, your support and unconditional love. My dearest of friends, you have lived and supported my dream. I could never have done all this without you, I love you infinitely. "Porque não há nada mais belo que o amor."
