There are several issues faced by a developer when holistic response-time analysis (HRTA) is implemented and integrated with a tool chain. The developer has to not only implement the analysis, but also extract unambiguous timing and tracing information from design model. We present an implementation of HRTA as a plug-in for an industrial tool suite Rubus-ICE that is used for component-based development of distributed real-time embedded systems. We present our preliminary findings about implementation issues and highlight our experiences. Moreover, we discuss our plan for testing and evaluating the integration of HRTA as a plug-in in Rubus-ICE.
