Hierarchical component models allow to better manage system design complexity compared to flat component models. However, many analysis techniques lack support for dealing with hierarchical models. This paper presents a general approach to use existing analysis on hierarchical component systems by means of a flattening transformation. The transformation can be partially applied, which provides a possibility for tradeoffs between analysis scalability, result precision and reusability concerns. The general approach has been implemented and evaluated in the context of ProCom, a hierarchical component model for real-time embedded systems. As a result, the paper describes a flattening transformation which preserves the ProCom operational semantics and presents the related optimizations.
