Symtavision launches the SymTA/S 3.0 and TraceAnalyser 3.0, fully integrated versions of system-level tools for model-based design and trace-based verification. Targeted at automotive, aerospace, automation and other performance- and safety-critical systems, the combination of SymTA/S 3.0 and TraceAnalyser 3.0 enables high efficiency and reliability for the dimensioning, optimisation, regression-testing, and verification of controllers and networks, focusing on load, task and message latencies, system schedulability, end-to-end timing, data consistency and other key properties that ensure system correctness.

SymTA/S 3.0 and TraceAnalyser 3.0

The launch of SymTA/S 3.0 and TraceAnalyser 3.0 creates a seamlessly integrated solution delivering full, round-trip support for model- and trace-based timing analysis. Engineers can now rapidly merge controller or network traces into existing SymTA/S models. They can start from traces and then change the system configuration virtually to predict the performance impact of additional tasks or messages, different scheduling strategies or faster hardware. This seamless integration of model- and trace-based timing analysis enables engineers to quickly iterate their designs as many times as they want, for both developments and evolutionary extension and optimisation of existing systems.

Furthermore, SymTA/S 3.0 enhances Distribution Analysis used to determine timing statistics and the probability of deadline violations. This complements Symtavision's leading Worst-Case Analysis used to determine hard timing bounds. SymTA/S 3.0 also provides direct CAN-ID support with both hexadecimal and decimal visualisation, in addition to assigning priority values for CAN bus configuration. The Report Generator has been enhanced to provide a Difference Report between two system revisions enabling engineers to undertake "what-if" analysis more easily. Additionally, the AUTOSAR XML import function has been enhanced to support shared variables, and the Communication Overhead Analysis capability has been improved to provide support for multi-core controllers.

TraceAnalyser 3.0 provides improved external tool integration including support for Vector Informatik's FlexRay trace/log file format and CAN multi-channel support for its CANoe ASC trace/log file import interface. A Report Generator, using the technology common to SymTA/S, has also been added.
