Timing analysis tool suite upgrades function-level and Ethernet analysis

Comprises SymTA/S and TraceAnalyzer tools, Symtavision 4.0 has been released by Luxoft Holding. It features new function level analysis and Ethernet network analysis upgrades, targeting significantly improved timing analysis of automotive engine control units (ECUs), networks and distributed systems.

For ECU timing analysis, Symtavision 4.0 includes a new data flow visualisation capability in the SymTA/S toolset, which allows fast analysis of the software and communication architecture. With the help of interactive filters, the data flow graphs can be tuned to show the right level of abstraction enabling full exploration of system performance at the function architecture level.

Major extensions to the Ethernet network timing analyses in SymTA/S meant that buffer occupancy in Ethernet switches can now be undertaken at the buffer level, allowing the validation of switch memory. This reduces the risk of dropped frames due to buffer overflows. There is also both simulation (system distribution) analysis and worst-case analysis. The addition of end-to-end jitter metrics provide an early hint as to the real-time capability of individual messages, says the company, and helps to identify potential data losses at the receiver. Worst-case latency analysis has also been extended to cover Ethernet AVB and support is now provided for AUTOSAR 4.2 Ethernet models, including Scalable service-Oriented MiddlewarE over IP (SOME/IP). For controlled area networks (CANs), a new dashboard is available that provides a quick overview of the status of a network.

To support the automated testing of automotive ECUs and networks (CAN, FlexRay, Ethernet), both the SymTA/S TraceAnalyzer tools offer advanced comparison of actual versus target behaviour, facilitating fast verification of measurements against the expected behaviour from the model. Additionally, the new activation pattern extraction feature allows quick modelling of non-periodic behaviour, such as interrupt triggering or sporadic frames, from traces.

The 4.0 tool suite offers usability improvements, including updated interfaces to trace tools such as Gliwa, iSYSTEM and Lauterbach, and copy-and-merge of elements between models, as well as performance improvements.

Luxoft will be demonstrating Symtavision 4.0 at Embedded World 2017 (Hall 4 – 432).
