“…These approaches are implemented within platforms such as OSATE and TOPCASED aiming the convenient reuse of existing tools like UPPAAL, Tina and Polychrony. In our work, we choose Ocarina [16], a tool suite that gathers analysis of AADL models and the automatic code generation towards AADL runtimes PolyORB-HI/Ada or C. We define a model transformation AADL2LNT implemented within Ocarina to automatically generate a formal specification from the AADL model using the LNT [7] language. LNT 2 is a process algebra based on two standards Lotos and E-Lotos.…”

The formal verification has become a recommended practice in safety-critical software engineering. The hand-written of the formal specification requires a formal expertise and may become complex especially with large systems. In such context, the automatic generation of the formal specification seems helpful and rewarding, particularly for reused and generic mapping such as hardware representations and real-time features. In this paper, we aim to formally verify real-time systems designed by AADL language. We propose an extension AADL2LNT of the Ocarina tool suite allowing the automatic generation of an LNT specification to draw a gateway for the CADP formal analysis toolbox. This work is illustrated with the Pacemaker case study.

“…AADL is backed with a large set of analysis tools 2 , covering many different domains: scheduling analysis like Cheddar [13] and MAST [14]; dependability assessment: AADL provides an annex for modeling propagation of error, like COMPASS project [15], or ADAPT [16]; behavioral analysis: mapping to formal methods and associated model checkers have been defined for Petri Nets [17], RT-Maude [18] and many others code generation: Ocarina implements Ada and C code generators for distributed systems [19]; mapping to hardware description language System-C [20].…”

Abstract-Architecture Description Languages (ADLs) support modeling and analysis of systems through models transformation and exploration. Various contributions made proposals to bring verification capabilities to designers through model-based frameworks and illustrated benefits to the overall system quality.Model-level analyses are usually performed as an exogenous, unidirectional and semantically weak transformation towards a third-party model. We claim such process can be incomplete and/or inefficient because gathered results lead to evolution of the primary model. This is particularly problematic for the design of Distributed Real-Time Embedded (DRE) systems that has to tackle many concerns like time, security or safety.In this paper, we argue why analysis should no longer be considered as a side step in the design process but, rather, should be embedded as a first-class citizen in the model itself. We review several standardized architecture description languages, which consider analysis as a goal. As an element of solution, we introduce current work on the definition of a language dedicated to the analysis of models within the scope of one particular ADL, namely the Architecture Analysis and Design Language (AADL).

“…AADL is an Architecture Description Language (ADL) suitable to describe systems, capturing the functional and non-functional concerns together with the operational platform. As the AADL provides modeling elements with a precise syntax and well-defined semantics, it is possible to : 1) perform analysis and 2) derive implementations thanks to code generation [4].…”

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 Verification & Validation activities towards system qualification. Still, few works evaluate the early integration of performance evaluation based on architectural models. In this paper, 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 efficiently support analysis activities in the early-stage design phases.
