DRTSS: a simulation framework for complex real-time systems

This paper describes a simulation framework called DRTSS, which allows its users to easily construct discrete-event simulators of complex, multi-paradigm, distributed real-time systems. Preliminary, high-level system designs can be entered into DRTSS to gain initial insight into the timing feasibility of the system. Later, detailed hierarchical designs can be evaluated and more detailed analysis can be undertaken. DRTSS is a member of the PERTS family of timing-oriented prototyping and verification tools [17]. It complements the PERTS schedulability analyzer tool by dealing with complex real-lime systems for which a priori schedulability analysis is difficult or impossible.
