From AMALTHEA to RCM and Back: a Practical Architectural Mapping Scheme

This paper focuses on the mapping between two industrial architectural languages: AMALTHEA and Rubus Component Model. Both languages are heavily used within the automotive domain for the design and timing analysis of automotive software, respectively. The main contribution of this paper is a mapping scheme between the two architectural languages enabling i) the translation of an AMALTHEA architecture into a Rubus Component Model architecture where high-precision timing analysis can be performed ii) and the back-propagation of the analysis results on the AMALTHEA architecture. We validate the applicability of the proposed mapping scheme using an industrial use case from the automotive domain: the brake-by-wire system. We discuss the industrial relevance and lessons learnt of this work using expert interviews.
