Timing analysis software supports LIN bus analysis

September 03, 2013 // By Christoph Hammerschmidt
With the launch of the timing analysis software SymTA/S 3.4, tool vendor Symtavision announces a new comprehensive 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.

The 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 analyse respective frame response times. An LDF (LIN Description File) interface also facilitates the import of LIN communication matrices. Seamless integration with the 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.

At the same time, the tool vendor announces version 3.4 of TraceAnalyzer, a solution for visualizing and analyzing timing data from both measurements and simulations, which seamlessly integrates with SymTA/S.
