In order to engineer software architectures of complex cyber-physical systems of different technical domains such that both time and effort efficient and truly interactive engineering of software architectures of complex cyber-physical systems is enabled, it is proposed to provide an automatic enforcement of multi-level Constraints across architectural Views. This provides, (i) with regard to architectural aspects of such a complex cyber-physical system being captured in Views including various Entities being related to each other and entities being related across various Views and (ii) that these multi-view Constraints particularly implying that the Constraints placed on the Entities in one View may affect the validity of the relations of the Entities in another View, an error-free engineering, (e.g., without violating at least one Constraint), together with a rapid, in particular visual, feedback of Constraints being invalidated and Entities involved in the Constraints.
