The TIMMO-2-USE project: Time modeling and analysis to use

Abstract : The paper presents the actual results of the TIMMO-2-USE project dedicated to time modeling and analysis in the domain of automotive embedded system design. A first result is the Timing Augmented Description Language (TADL2) that offers capabilities for symbolic time expressions modeling, probabilistic timing information and timing constraints applied on mode definitions. The syntax and semantic of such extensions are presented. These extensions are aligned with EAST-ADL and AUTOSAR timing models. Based on these extensions, new algorithms and tools are developed to analyze and validate TADL2 specifications. Conjointly with these aspects, a new methodology based on industrial use cases is proposed compatible with those of TIMMO, ATESST2 and AUTOSAR. This methodology solves specific issues related to timing in an automotive system design, such as time budgeting. The TIMMO-2-USE work and results are driven by industrial use cases. Use cases are the corner stone of the project as they are used as input for providing requirements for the language, the algorithm development, and the methodology development but also because the same are used for a validation of the results.
