With the launch of SymTA/S 3.4, Symtavision has announced a comprehensive, new timing design and analysis capability for LIN (Local Interconnect Network), the low-cost, distributed networking protocol used primarily in automotive and industrial applications. SymTA/S 3.4 also features FlexRay dynamic segment analysis improvements, AUTOSAR XML 4.x import with Ethernet support, improved Gantt loading, individual license check out and scripting efficiency improvements. At the same time, Symtavision has announced version 3.4 of TraceAnalyzer, its powerful solution for visualizing and analyzing timing data from both measurements and simulations which seamlessly integrates with SymTA/S.

The new LIN capability in SymTA/S 3.4 supports System Distribution and Worst Case analysis with multiple scheduling tables and multiple frame mapping as well as defining standard parameters such as individual bus speeds, time bases and jitter, enabling engineers to parameterize multiple LIN networks and analyze respective frame response times. An LDF (LIN Description File) interface also facilitates the importation of LIN communication matrices. Seamless integration with the well-established SymTA/S analyses for CAN, Ethernet, FlexRay and OSEK / AUTOSAR-based ECUs facilitates end-to-end timing analysis for distributed functions via LIN, as well as the connection of LIN to CAN, Ethernet and FlexRay networks via gateways.

Additionally, the existing SymTA/S FlexRay model has been enhanced to support the FlexRay 2.x standard with cycle multiplexing in the dynamic segment for System Distribution and Worst Case analyses enabling engineers to analyze end-to-end mixed bus scenarios both in terms of full synchronization and individual triggering. As AUTOSAR support for Ethernet network complexity continues to expand, the automated import of Ethernet network descriptions in AUTOSAR XML 4.x format greatly simplifies and improves the efficiency of Ethernet analysis as the model no longer needs to be manually defined. The ability to check out individual licenses and to define which licenses / functionality are needed during runtime, greatly improves usability and streamlines license usage.

Improved Gantt loading is introduced in both SymTA/S 3.4 and TraceAnalyzer 3.4. With the process now undertaken in background, engineers gain greater control while loading large Gantts. Furthermore, the ability to copy and paste scripting API names and parameters improves the efficiency of working with scripts.

“With the launch of SymTA/S 3.4, we are, once again, significantly extending the capability of our awardwinning system-level tool suite for planning, optimizing and verifying embedded real-time systems,” said Dr. Marek Jersak, CEO of Symtavision. “Fully integrated support for LIN significantly enhances our ability to analyze the timing design of in-vehicle networks at all levels. Coupled with improvements to our FlexRay and Ethernet analyses, AUTOSAR 4.x import and enhanced usability, they further confirm our position as the global leader in the provision of tools for the timing design and timing verification of performance- and safetycritical networks.”

SymTA/S 3.4 and TraceAnalyzer 3.4 will be demonstrated to customers at the 7th Annual Symtavision NewsConference on timing analysis to be held in Braunschweig, Germany from 25th to 26th September 2013.

The Symtavision NewsConference provides a unique opportunity for engineers, managers, technology experts and researchers to discuss trends and solutions for the development of reliable, safe and efficient embedded real-time systems. This year the keynote speech will be given by Prof. Dr. Rolf Ernst, of Braunschweig University. Presentations will be made by Symtavision customers including Bosch, General Motors, Daimler, Fiat and Volkswagen.
