| Timing design methodology for AUTOSAR series development |
Braunschweig, Germany – 22nd June 2011. Symtavision, a leading global solutions provider for real-time systems design and verification, has announced a series of collaborations on timing design and verification with leading AUTOSAR modeling tool vendors. The collaborations have resulted in the integration of Symtavision’s SymTA/S scheduling analysis tool suite for system-level timing design and timing verification with aquintos/Vector’s PREEvision, Continental Engineering Services’ CESSAR-CT, dSPACE’s SystemDesk and ETAS’ i-SOLAR.
The standardization afforded by AUTOSAR and the emergence of associated modeling tools has already contributed significantly to an enormous improvement in productivity from a software development perspective. However, in terms of system integration, answers are needed to key questions such as what is the right dimensioning for ECUs in order to implement the functional range in a reliable and cost-effective way, which resources are consumed by the basic software and which parts could be freed by optimization, what is the best mapping from the functional architecture to the software architecture related to the optimized use of available resources, required reserves and safety requirements? Answering them requires an in-depth understanding and control of the timing and resource usage of the system along with their consistent consideration in the AUTOSAR design process.
SymTA/S provides engineers with this understanding enabling them to capture all the timing properties along with the existing AUTOSAR meta-model, today with the commonly used AUTOSAR Release 3.2 and in the future with the timing extensions in AUTOSAR 4.0. Its integration with established AUTOSAR modeling tools has enabled timing design and verification techniques to be introduced to all stages of the AUTOSAR development process from initial Load Analysis for execution time budget optimization through to subsequent Virtual Scheduling for concept optimization and final Event Chain Verification for ECU configuration optimization and integration. Tool integration is achieved using both AUTOSAR’s standardized XML file-based configuration exchange and ARTOP Eclipse plug-in of base methods for AUTOSAR tools.
“Our various collaborations on timing design and verification add a critical new dimension to the overall effectiveness of the AUTOSAR development capabilities offered by aquintos/Vector, Continental Engineering Services, dSPACE and ETAS and confirms our market leadership in AUTOSAR timing design and verification,” said Dr. Marek Jersak, CEO of Symtavision. “While AUTOSAR provides a standard basis for specifying software architectures and ECU configurations, it is timing analysis that enables engineers to determine precisely how good their designs really are and optimize them accordingly.”
