Symtavision has announced the release of SymTA/S 3.6, delivering up to 20 times faster system distribution and worst-case analysis runtime performance, as well as reduced memory usage, enhanced multicore data consistency analysis and FlexRay system distribution analysis along with improved AUTOSAR support and Trace importation. At the same time, Symtavision has released TraceAnalyzer 3.6, which includes improved trace import and interoperability with Lauterbach tracing software.

SymTA/S 3.6 delivers runtime speed improvements for system distribution and worst-case analyses of between two and twenty times, and often more, depending on the system complexity. Overall memory usage for analysis runs has also been significantly reduced with 100+ runs also requiring no more RAM than that required by a single run previously.

Data consistency analysis of multicore systems has been enhanced with an improved capability to explicitly model call types for variable access, added modelling of protected variable accesses such as double buffering and improved performance for systems with many variables. The FlexRay system distribution analysis facilitates analysis of frame displacement in the dynamic segment, data loss and used/unused slots per cycle.

The ability to determine system distribution analysis starting behaviour has also been enhanced with explicit modelling of the starting points of elements to facilitate the simulation of start-up behaviour and enable user-defined activation patterns. There is also a data annotation element enabling any kind of additional information in a model to be stored in a generic way.

The AUTOSAR 3.x/4.x importer has been enhanced with support for ARXML files generated by Vector DaVinci and the extraction of more information from incomplete ARXML files. Additionally, trace import in SymTA/S and TraceAnalyzer works in conjunction with Symtavision’s Lauterbach Trace32 interface and supports more detailed traces such as wait-release behaviour.

“The release of SymTA/S 3.6 and TraceAnalyzer 3.6 delivers on our commitment to continuous product improvement,” said Dr. Kai Richter, CTO, Symtavision. “The speed improvements of up to 20 times to the system distribution and worst-case analyses in version 3.6 of the tools, along with the enhanced features we have incorporated, will continue to maintain their position as the market-leading timing analysis solutions for planning, optimising and verifying ECUs, buses and networked E/E architectures.”
