Background and Version History Clause Samples

Background and Version History. Let us be reminded that at the beginning of the MAENAD project the analysis engine should have been provided as a third-party tool. On the other hand, after EDONA and ATESST2, CEA worked on the implementation of schedulability analysis algorithms as part of its research activities (not included in the MAENAD project) in its own ▇▇▇▇▇-based plug-in called Qompass. This timing analysis support was not completely compliant with timing analyses identified as best-suited for EAST-ADL design models (Section 2.2). Moreover, in order to directly analyse EAST-ADL models, a transformation between EAST-ADL profile models and entry models for Qompass was needed. During year 2 the Qompass timing support has been adapted/enhanced in order to support EAST- ADL design-level timing analyses. An EAST-ADL/Qompass transformation has been developed as well. A new version of the Timing Analysis plug-in, has been released at M24 embedding these new features. At the end of year 2, the input model for the Qompass tool assumed only linear event chains, where each chain contained a linear sequence of functions and where neither functions nor stimuli could belong to more than one event chain. In order to support the analysis of the brake-by-wire (BBW) system, an extension was needed, as the BBW owns functions belonging to multiple event chains. With the latest release, this extension has been implemented and now Qompass can run on the BBW model.
