This paper presents a representative case study of bridging UML/MARTE (unified modeling language/ modeling and analysis of real time and embedded systems) to FIACRE (intermediate format for the architectures of embedded distributed components), and discusses in detail two sub-problems of semantic mapping and syntactic transformation respectively. At the semantic level, the semantic mapping rules are developed using model transformation technology so as to implement the transformation between metamodels. At the syntactic level, the concrete syntax rules are built on the metamodels so that textual programs could be generated. Based on the case study, the general framework and corresponding key techniques are discussed. In addition, both the advantages and deficiencies of the work are concluded.
