Timing design tool gets support for FlexRay, Autosar 3.x/4.x

September 09, 2014 // By Christoph Hammerschmidt
At its customer conference this week, software tool vendor Symtavision will preview the latest release of its SymTA/S system-level timing design and verification tool. The new release - it bears version number 3.6 - features improvements in system distribution analysis performance, memory usage, multicore data consistency analysis and support for the FlexRay high-speed data bus as well as for the Autosar 3.x/4.x software environments. In addition, it offers analysis of start-up behaviour and trace import.

Due to the improved System Distribution Analysis performance, SymTA/S 3.6 is said to run up to 20x faster in some user cases. Memory usage for analysis runs has also been reduced - more than a hundred runs now require no more memory than that previously required by a single run. The FlexRay system distribution analysis preview now 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.

The data consistency analysis of multicore systems now offers the ability to model explicit call types for variable access and improved performance for systems with many variables. In addition, 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 now works in conjunction with the Lauterbach Trace32 interface and supports more detailed traces such as wait-release behaviour.
