Autostar

The AUTOSAR modeling and software validation platform can be used by safety engineers, advanced development teams, AUTOSAR consortium members and software integrators to evaluate software runnable operation across multiple ECUs.

The AUTOSAR modeling environment provides end-to-end functional simulation with fault injections. The simulations, test whether faults intended to be addressed per the ISO 26262 safety standards, are being properly detected and mitigated by the configured AUTOSAR system.

The AUTOSAR environment provides a graphical configuration of the BSW modules including the RTE (primarily generated), the (static) configuration of the OS (tasks, schedules, events, OS-Applications, execution time supervision, protection hooks, COM stack, and configuration of BSW modules such as the Watchdog Manager (aliveness supervision, deadline monitoring, program flow monitoring), and Diagnostic Event Manager.

The safety engineers will ensure that the various AUTOSAR services useful in building safety-critical systems are being used and configured correctly in a manner that will achieve the safety goals defined by the ISO team. The ISO Safety Team will conduct timing and memory analysis. These safety-critical analysis tests the schedulability of dynamic timing situations with fault-injection, validate the AUTOSAR configuration, identify testing requirements, develop test plans, and generate fault scenarios. AUTOSAR integration teams can conduct simulations of the final configurations to determine the cause of unexpected behaviors.

Advanced engineering can explore new design concepts and architectures. Examples are the role of multi-core processors in safety architectures, and the use of hardware virtualization (hypervisors) in achieving freedom from interference in safety architectures. Implementation artifacts for these new concepts or architectures might not yet exist, abstract models rapidly created in VisualSim provides significant visibility into system operation. AUTOSAR consortium team can model and simulate proposed new extensions to the AUTOSAR architecture to aid in the evaluation (acceptance vs. rejection) of new proposals. New services for infrastructure health management, replication management, safety supervision and monitoring services could be proposed, modeled, and simulated against intended use-cases, and evaluated for effectiveness and resource consumption.
