The rate and reactivity figures of embedded systems are distinctly influenced by the chosen scheduling policy since embedded software processes more and more dominate the functionality of embedded systems. Seeking a suitable schedule policy typically requires some heuristics in conjunction with analytic approaches. A stand-alone scheduling simulator can considerably help reducing these efforts. However, a tedious integration work will be required in order to jointly validate both behavioural and architectural design decisions. Therefore, we present an open framework for real-time scheduling simulation by exploiting the SystemC modeling style. Especially the real-time software modeling capabilities of SystemC are enhanced to a large extent by this work, which allows an integration of software tasks scheduling simulation into existing approaches of modeling using SystemC. Thus, design alternatives, scheduling decisions, and associated real-time performance can be explored in early design phases.
