These loops can be organized into a variety of architectural patterns. Although several authors have addressed the need to make feedback loops first-class entities, little attention has been given to providing solid tool support for their engineering and implementation. In this paper, we present SimSOTA - an integrated Eclipse plug-in tool to architect, engineer and implement self-adaptive systems based on our feedback loop-based approach. SimSOTA adopts model-driven development to model and simulate complex self-adaptive architectural patterns, and to automate the generation of Java-based implementation code for the patterns. The approach is validated using a case study in cooperative electric vehicles.en004conference paper
