The TrueTime toolbox simulates real-time control sys- tems, including platform-specific details like process scheduling, task execution and network communications. Analysis using these models provides insight into platform- induced timing effects, such as jitter and delay. For safety- critical applications, the Time-Triggered Architecture (TTA) has been shown to provide the necessary services to create robust, fault-tolerant control systems. Communication in- duced timing effects still need to be simulated and analyzed even for TTA-compliant models.
