As modern systems are integrating exceeding number of components for better performance and functionality, early full-system simulation tools have become essential for validating complex concurrent system interaction activities. In the past decades, many useful timing-accurate system simulation tools have been developed; however, we find that even for the most efficient techniques, more than 90% of...
Predicting and analyzing runtime performance characteristics is a vital step in the development process of parallel discrete event simulations. For instance, model developers need to identify and eliminate performance bottlenecks within a simulation model in order to derive a model structure that aids parallel execution. Similarly, developers of parallel simulation frameworks require means of assessing...
The simulation framework VSimRTI provides the integration of multiple heterogeneous simulators to enable V2X application simulations. In order to increase the performance and scalability of complex V2X simulations, a new time management service has been implemented that enables optimistic synchronization in federated simulations. This paper presents the underlying mechanisms as well as the resulting...
SystemC is a system-level modeling language that offers a wide range of features to describe concurrent systems at different levels of abstraction. The SystemC standard permits simulators to implement a deterministic scheduling policy, which often hides concurrency-related design flaws. We present a novel compiler for SystemC that integrates a formal and scalable race analysis. This analysis combines...
