Adds new function-level timing analysis and Ethernet network analysis upgrades including SOME/IP and worst-case AVB analysis

Munich, Germany – 1st March 2017.Luxoft Holding, Inc (NYSE: LXFT), a leading provider of software development services and innovative IT solutions to a global client base, has launched a major new version of its Symtavision timing analysis solution for planning, optimizing and verifying embedded real-time systems, which comprises the award-winning SymTA/S and TraceAnalyzer tools. Symtavision 4.0 features new function level analysis and Ethernet network analysis upgrades targeting significantly improved timing analysis of automotive ECUs, networks and distributed systems. 

For ECU timing analysis, Symtavision 4.0 includes a new data flow visualization capability in the SymTA/S toolset, which allows fast and easy 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.

Symtavision 4.0 also includes major extensions to the Ethernet network timing analyses in SymTA/S. Buffer occupancy in Ethernet switches can now be undertaken at the buffer level, allowing the validation of switch memory and thereby reducing the risk of dropped frames due to buffer overflows. This is supported in 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 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 SOME/IP. For CAN networks, 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 in Symtavision 4.0 offer advanced comparison of actual versus target behavior, facilitating fast verification of measurements against the expected behavior from the model. Additionally, the new activation pattern extraction feature allows quick modeling of non-periodic behavior, such as interrupt triggering or sporadic frames, from traces. Furthermore, the Symtavision 4.0 tool suite offers numerous 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.

“Robust timing analysis of ECUs, networks and distributed systems becomes ever more crucial as the complexity of automotive electronics continues to grow,“ said Marek Jersak, Director, Luxoft Automotive UTH Practice. “SymTA/S and TraceAnalyzer already have an enviable track record in the market and as the emphasis in timing design, analysis and verification of automotive electronics continues to shift towards increased driver assistance and the automated driving domains, we have continued to push the boundaries with the launch of Symtavision 4.0.“

 

 

Feb. 23, 2016: Effective timing design, analysis and verification essential to the development of Advanced Driver Assistance Systems (ADAS)

With discussion around the subject of automated driving gathering pace, the development of Advanced Driver Assistance Systems (ADAS) looks set to become the ‘next big thing’ in automotive electronics. According to Symtavision, the global leader for timing design and timing verification for embedded real-time systems, the development of ADAS introduces totally new challenges and significantly higher levels of design complexity, making the adoption of effective timing design, analysis and verification tools essential in their design.

“Even in terms of where automotive electronics is today, ADAS is a disruptive technology that will fundamentally challenge the way automotive E/E and software systems have been built and integrated in the past,” said Dr. Kai Richter, CTO of Symtavision. “ADAS adds enormously to the software cross-dependencies in vehicles, which, in order to execute all the required new functions, will require additional levels of computing performance and network communications far exceeding that of established vehicle E/E systems. To make the step-change needed to turn concepts into reality, the integration of effective timing design, analysis and verification tools into the overall design process will be crucial.”

Symtavision, the global leader in timing analysis solutions for planning, optimizing and verifying embedded real-time systems, has extended its collaboration with iSYSTEM, a leading independent provider of embedded software debugging, analysis and test tools, resulting in the announcement of significantly improved integration between Symtavision’s SymTA/S and TraceAnalyzer timing design tools and iSYSTEM’s debug and trace tools and a round-trip workflow. The improved integration will better ensure the safety and reliability of automotive real-time software at the same time as speeding up development and reducing costs.

The collaboration delivers Symtavision tool support for Best Trace Format (BTF), the preferred file format for the iSYSTEM debug and trace tool, enabling trace data from single and multicore ECU’s to be imported intoTraceAnalyzer for visualization and analysis of timing traces and validation of ECU scheduling. Timing models generated from the traces can be processed further in SymTA/S to perform worst-case and statistical timing analyses, as well as to virtually change the scheduling and explore/optimize the overall software architecture. The optimized configuration can be passed back to the iSYSTEM debug and trace tool via an ECU configuration tool and uploaded to the target, completing the round-trip workflow.

Sept. 03, 2015: Symtavision supports Key Timing Use Cases for ECU Software Development

download PR

Symtavision, the global leader for timing design and timing verification for embedded real-time systems, has identified key timing use cases for a systematic, timing-enriched ECU development process, which saves development time and unit cost and increases the realization probability and maturity level of ECU development projects.

Systematic ECU development starts with specifying the function architecture and defining the requirements on the desired functions. From this, reasonable software architectures and schedules are developed, followed by the actual software development with integration and test at every release. The entire process is typically supported by appropriate assessments and executed through deliveries according to a negotiated timeline between the OEM and the supplier (or ECU development team).
