This paper focuses on the mapping between twoindustrial architectural languages: AMALTHEA and RubusComponent Model. Both languages are heavily used within theautomotive domain for the design and timing analysis of automo-tive software, respectively. The main contribution of this paperis a mapping scheme between the two architectural languagesenabling i) the translation of an AMALTHEA architecture intoa Rubus Component Model architecture where high-precisiontiming analysis can be performed ii) and the back-propagationof the analysis results on the AMALTHEA architecture. Wevalidate the applicability of the proposed mapping scheme usingan industrial use case from the automotive domain: the brake-by-wire system. We discuss the industrial relevance and lessonslearnt of this work using expert interviews
