Modeling a BSG-E automotive system with the Timing augmented description language

International audienceModeling and analysis of time is a key issue for the correct development of automotive distributed embedded system. The paper presents the new extensions of the Time Augmented Description Language, applicable at the different abstraction levels of an EAST-ADL/AUTOSAR design, which enable a precise modeling of the multi clock characteristics of distributed systems together with parameterized timing expressions. In this paper, we highlight some critical issues for high-level modeling of time with the Delphi application of a Box Servitude Generic - External (BSG-E). This industrial example illustrates timing constraints coming from both hardware and software parts of the syste
