Fault Localization of Energy Consumption Behavior Using Maximum Satisfiability

In model-based analysis of energy consumption behavior, detecting energy bugs is formulated as a model checking problem. Model checkers can check the energy consumption behavior automatically, but significant manual effort is required to study the generated counter-example trace for finding the root causes of the failure. This effort can be reduced by using a formula-based automatic fault localization method. The present paper proposes a new trace formula, encoding all potential transition sequences, with modest assumptions on the failure. The paper also discusses the precision of the identified root causes and limitations of the adapted failure model.
