[en] Model-Driven Engineering (MDE) is a relevant approach to support the engineering of distributed embedded systems with performance and dependability constraints. MDE involves models definitions and transformations to cover most of the system life-cycle: design, implementation and Verifi cation & Validation activities towards system quali fication. Still, few works evaluate the early integration of performance evaluation based on architectural models. In this report, we investigate the early-stage use of analysis in AADL modeling. Precisely, we exemplify on an avionics case study how to dimension the data flows for an application distributed over an AFDX network. Based on the insight from this study, we suggest a simple framework and associated techniques to e fficiently support analysis activities in the early-stage
design phases.
