Timing analysis also for CAN FD

Symtavision (USA) has released the version 3.3. of its SymTA/S system-level tool suite for planning, optimizing and verifying embedded real-time systems. Besides the classic CAN protocol, it also supports the improved CAN protocol (also known as CAN FD).

New Gantt Grouping and Filter Management

THE VERSION 3.3 FEATURES drag-and-drop support, buffer fill level analysis as well as Gantt chart customization. Other improvements include the customizable wizard framework and the support of the CAN FD protocol. At the same time, the toolmaker has announced TraceAnalyzer 3.3, a new version of its tool for visualizing and analyzing timing data from both measurements and simulations, which integrates with system-level tool suite.
Dr. Marek Jersak, CEO of Symtavision said: “The launch of SymTA/S 3.3 and TraceAnalyzer 3.3 represent a significant step forward for timing design and timing verification of embedded real-time systems.
The new analyses and further improved design features address the market trend for timing-aware system design, as well as specific requirements of our customers who need to create high performance, reliable and safe embedded systems in the automotive, aerospace and industrial automation markets.”

The tool also extends the existing CAN timing analysis capability with integrated support for the improved CAN data link layer. To perform CAN FD analysis only a few scheduling-relevant parameters are required including the dataphase speed. Everything else is transparent to users as the tool automatically handles other scheduling items such as the bits that are sped up, the correct CRC size, which varies according to the payload, and inserting stuff bits.
The Gantt filtering option automatically hides unimportant trace lines reducing those shown in the viewer only to those that are most relevant. The visualization can be individually customized or pre-defined visualization schemes can be reused.
The Gantt grouping option supports collapsing trace lines to a single line. Multiple groups are supported and can be easily set up using drag and drop functions. Groups are also context sensitive and automatically generated depending on the selected element. In addition, pre-defined groups can be applied.

Both SymTA/S 3.3 and TraceAnalyzer 3.3 include the customizable wizard framework, enabling users to create their own graphical interface through scripting. This allows automation of custom workflows consisting of individual commands for interfacing, design, analyses and results setup simple annotations in a script file define the graphical interface elements and parameters for script execution. A variety of input parameter types are supported such as strings, integer and Boolean as well as the manufacturer’s internal objects like tasks, frames, buses or ECUs. More complex types like the event model editors, a file chooser or even a choice type complete the portfolio.

The company has scheduled the 7th Symtavision News Conference in Bruanschweig (Germany) on September (25th and 26th), 2013. The event provides the opportunity for learning and exchanging ideas. Some carmakers will report about their experiences with the tools.
