22.09.2011: Launch of SymTA/S 3.0 and TraceAnalyzer 3.0 delivers integrated model-based and trace-based timing analysis.
Round-trip support for model-based and trace-based timing design and verification enables outstanding analysis functions and seamless process integration.
Symtavision, the global leader for timing design and verification for embedded real-time systems, has launched SymTA/S 3.0 and TraceAnalyzer 3.0, the first fully integrated versions of these highly successful system-level tools for model-based design and trace-based verification. Targeted at automotive, aerospace, automation and other performance- and safety-critical systems, the combination of SymTA/S 3.0 and TraceAnalyzer 3.0 enables unparalleled efficiency and reliability for the dimensioning, optimization, regression-testing, and verification of controllers and networks, focusing on load, task and message latencies, system schedulability, end-to-end timing, data consistency and other key properties that ensure system correctness.
The launch of SymTA/S 3.0 and TraceAnalyzer 3.0 creates a seamlessly integrated solution delivering full, round-trip support for model- and trace-based timing analysis. Engineers can now rapidly merge controller or network traces into existing SymTA/S models. They can start from traces and then change the system configuration virtually to predict the performance impact of additional tasks or messages, different scheduling strategies or faster hardware. This seamless integration of model- and trace-based timing analysis enables engineers to quickly iterate their designs as many times as they want, for both new developments and evolutionary extension and optimization of existing systems.
Furthermore, SymTA/S 3.0 significantly enhances Distribution Analysis used to determine timing statistics and the probability of deadline violations. This complements Symtavision’s leading Worst-Case Analysis used to determine hard timing bounds. SymTA/S 3.0 now also provides direct CAN-ID support with both hexadecimal and decimal visualization, in addition to assigning priority values for CAN bus configuration. The Report Generator has been enhanced to provide a Difference Report between two system revisions enabling engineers to undertake “what-if” analysis more easily. Additionally, the AUTOSAR XML import function has been enhanced to support shared variables, and the Communication Overhead Analysis capability has been improved to provide support for multi-core controllers.
TraceAnalyzer 3.0 provides improved external tool integration including support for Vector Informatik’s new FlexRay trace/log file format and CAN multi-channel support for its CANoe ASC trace/log file import interface. A new Report Generator, using the technology common to SymTA/S, has also been added.
“Using SymTA/S and TraceAnalyzer in combination makes a huge contribution to efficiency in terms of meeting customers’ timing design and verification requirements. Many of them have been requesting closer alignment of the two tools in order to provide a more natural fit with their design processes,” said Dr. Marek Jersak, CEO of Symtavision. “This is precisely what we have delivered with the launch of SymTA/S 3.0 and TraceAnalyzer 3.0 - comprehensive round-trip support for model- and trace-based timing analysis in a seamless environment with a consistent user interface. Together they deliver unparalleled design productivity and quality when planning, evolving, implementing and verifying embedded real-time systems. Additionally, the introduction of significant new and improved process integration features as well as timing analysis functionality to both SymTA/S and TraceAnalyzer, have further enhanced engineer productivity.”
22.06.2011: Symtavision collaborates with leading AUTOSAR modeling tool vendors on timing design and verification
Symtavision’s SymTA/S scheduling analysis tool suite integrated with aquintos/Vector, Continental Engineering Services, dSPACE and ETAS AUTOSAR modeling tools
Symtavision, a leading global solutions provider for real-time systems design and verification, has announced a series of collaborations on timing design and verification with leading AUTOSAR modeling tool vendors. The collaborations have resulted in the integration of Symtavision’s SymTA/S scheduling analysis tool suite for system-level timing design and timing verification with aquintos/Vector’s PREEvision, Continental Engineering Services’ CESSAR-CT, dSPACE’s SystemDesk and ETAS’ i-SOLAR.
The standardization afforded by AUTOSAR and the emergence of associated modeling tools has already contributed significantly to an enormous improvement in productivity from a software development perspective. However, in terms of system integration, answers are needed to key questions such as what is the right dimensioning for ECUs in order to implement the functional range in a reliable and cost-effective way, which resources are consumed by the basic software and which parts could be freed by optimization, what is the best mapping from the functional architecture to the software architecture related to the optimized use of available resources, required reserves and safety requirements? Answering them requires an in-depth understanding and control of the timing and resource usage of the system along with their consistent consideration in the AUTOSAR design process.
SymTA/S provides engineers with this understanding enabling them to capture all the timing properties along with the existing AUTOSAR meta-model, today with the commonly used AUTOSAR Release 3.2 and in the future with the timing extensions in AUTOSAR 4.0. Its integration with established AUTOSAR modeling tools has enabled timing design and verification techniques to be introduced to all stages of the AUTOSAR development process from initial Load Analysis for execution time budget optimization through to subsequent Virtual Scheduling for concept optimization and final Event Chain Verification for ECU configuration optimization and integration. Tool integration is achieved using both AUTOSAR’s standardized XML file-based configuration exchange and ARTOP Eclipse plug-in of base methods for AUTOSAR tools.
“Our various collaborations on timing design and verification add a critical new dimension to the overall effectiveness of the AUTOSAR development capabilities offered by aquintos/Vector, Continental Engineering Services, dSPACE and ETAS and confirms our market leadership in AUTOSAR timing design and verification,” said Dr. Marek Jersak, CEO of Symtavision. “While AUTOSAR provides a standard basis for specifying software architectures and ECU configurations, it is timing analysis that enables engineers to determine precisely how good their designs really are and optimize them accordingly.”

05.04.2011 Launch of TraceAnalyzer 1.2 delivers 10x speed improvement
Visualizes timing traces for automotive, aerospace, automation and transportation electronics development
Symtavision, a leading global solutions provider for real-time systems design and verification, has launched TraceAnalyzer 1.2 which delivers a ten-fold speed improvement in terms of visualizing and analyzing timing trace and log data for ECUs, controllers, processors, buses and networks, while also reducing memory requirements ten-fold.
The Symtavision TraceAnalyzer is a powerful tool for visualizing system timing in terms of the constituent ECUs, controllers, processors, buses and networks. With traces imported from standard trace probes, Symtavision TraceAnalyzer visualizes the trace and analyzes the timing, so that key timing parameters can be identified and properly understood, and generates statistics on execution times, interrupt patterns, communication bursts and resource utilization, amongst others. It provides visual clarity showing controller and bus schedules with events, blocking and pre-emptions and details the timing chains so that engineers can see the flow of signals and data through the system including data loss and multiple reads of the same data. Results are provided both graphically and in tabular form.
Symtavision TraceAnalyzer is also capable of automatically generating system timing models for SymTA/S, Symtavision’s de-facto industry-standard tools suite for system-level timing design and timing verification. Symtavision recently announced SymTA/S 2.4 incorporating a wealth of new and improved features targeted at the automotive electronics, aerospace, automation and transportation markets including enhanced support for multi-core processors and AUTOSAR.
“Understanding system timing and performance is fundamental to designing and verifying real-time systems,” said Dr. Marek Jersak, CEO of Symtavision. “As such, tracing is now typically applied to log the timing of relevant events. However, the challenge is to efficiently analyze trace data and quickly identify timing problems along with their root causes. The Symtavision TraceAnalyzer provides engineers with an extremely powerful tool for visually analyzing this data and, with the launch of TraceAnalyzer 1.2, the ability to perform analyses up to 10 times faster than before.”
In the coming months, Dr. Jersak, CEO of Symtavision, will be giving talks on the techniques and tools for system-level timing design and timing verification at SAE World Congress 2011 (April 13, Detroit), ESC 2011 Silicon Valley (May 5, San Jose) and DAC 2011 (June 5, San Diego) in the USA.
03.03.2011 Launch of SymTA/S 2.4 further strengthens system-level timing design and verification
Major new version delivers significant new real-time modelling, analysis and process integration improvements including enhanced support for multi-core processors and AUTOSAR
Symtavision, a leading global solutions provider for real-time systems design and verification, has launched SymTA/S 2.4, a major new version of its highly successful tools suite for system-level timing design and timing verification. SymTA/S 2.4 incorporates a wealth of new and improved features targeted at the automotive electronics, aerospace, automation and transportation markets including enhanced support for multi-core processors and AUTOSAR.
The SymTA/S tools suite helps engineers conquer the design challenges of complex, safety- and performance-critical embedded real-time systems including controllers, processors, bus/networks and complete integrated systems, by facilitating their rapid and cost-effective design, optimization and timing verification, from early-phase estimation though to final certification.
New features in SymTA/S 2.4 include support for importing and optimizing AUTOSAR electronic control unit (ECU) and network configurations, multi-core ECU performance analysis and partitioning, end-to-end worst-case and statistical timing analysis, multi-dimensional timing dependency and data consistency analysis, enhanced PYTHON scripting and remote control tool automation.
SymTA/S 2.4 significantly improves automotive process integration with the inclusion of a new AUTOSAR XML import interface enabling AUTOSAR ECU and network configuration import and optimization. With SymTA/S 2.4 engineers can easily extract the architecture and related parameterization relevant for system-level timing analysis. It also facilitates tighter coupling with third-party AUTOSAR architecture design and ECU configuration tools equipped with XML export support.
With the enhanced multi-core processor performance analysis and partitioning support in SymTA/S 2.4, engineers are able to ensure their software designs have a balanced load on all cores, that all timing deadlines are met and that the software architecture is optimized for further multi-core development.
By analyzing delays occurring between sensors and actuators as worst-case and statistical typical-case values, the new end-to-end worst-case and distribution timing analysis capabilities in SymTA/S 2.4 enable systems to be easily optimized for both hard real-time and best-effort communication.
The multi-dimensional timing analysis focuses on scheduling offsets. Engineers can optimize a system by varying task and communication scheduling offsets and analyzing the impact on real-time performance. The data consistency analysis focuses on memory-based communication in pre-emptive real-time systems, enabling engineers to improve communication layouts by verifying if a variable can change in-between multiple reads.
The inclusion of a new remote control feature in SymTA/S 2.4 using a web service based on SOAP and including a dedicated API for controlling SymTA/S improves tool automation and tool-chain integration. The scripting capability has also been significantly improved with the integration of the Python programming language enriched with a dedicated API for controlling SymTA/S.
“SymTA/S is fast becoming the de facto industry standard, system-level scheduling analysis and optimization tools suite for complex, safety- and performance-critical embedded real-time systems,” said Dr Marek Jersak, CEO of Symtavision. “The launch of SymTA/S 2.4 continues to extend its market-leading position and system-level credentials with the introduction of significant process integration enhancements and new timing analyses to improve the design of complex, safety- and performance-critical embedded real-time systems.”

20.11.2010: SymTA/S for Migration from Single-core to Multi-core ECU-Software on Infineon Microcontrollers
Braunschweig – 20th November 2010. Symtavision, one of the leading tool vendors for timing and scheduling analysis in the field of complex, safety and mission-critical embedded real-time systems, has announced that its scheduling analysis tool suite SymTA/S supports the systematic migration of hard real-time software from a single-core to a multi-core platform, in particular on microcontrollers of Infineon Technologies.
The increasing performance requirements of embedded applications in the automotive domain often lead to multi-core approaches in order to reach the desired features at reasonable costs. The necessary migration of software from single-core to multi-core systems however raises several challenges.
The traditional approach is to modify software in small steps, and continuously check results. When porting software to multi-core architectures however, small steps may not always be feasible. The controller architecture is not only changed in terms of additional cores, but also in terms of supported clock rates, memory architecture, communication architecture or instructions of the cores, and therefore run-time may change considerably. The new architecture may require new compiler versions and operating systems, again possibly influencing the run- time behaviour.
Major questions for developers in the migration process are:
How shall the user map and partition software, using the existing hardware resources efficiently? What are actually the metrics for a successful transition from a single-core application to a multi-core application? How does the analysis of the runtime behaviour work and how is it affected, are deadlines still fulfilled by the software?
The decision, which runnables should be mapped to which cores and which data containers lay in which memories, is strongly influenced by communication overheads. Communication between the cores, realized through IOC (Inter OS-Application Communication) in AUTOSAR 4, and also the communication with external memories can lead to significant additional execution times of runnables. These communication overheads can eat up all expected performance from a multi-core CPU. The question is how huge are these overheads and how could they be reduced?
To assess if a certain mapping has large or small overheads several steps are necessary.
First a "cost catalogue" for several applicable communication mechanisms between the cores is determined. The data is measured with a benchmark developed by Gliwa GmbH on the target hardware and the selected operating system; however, still independent from the user application.
Next the user application is modelled directly in SymTA/S or it is imported into SymTA/S, based on an AUTOSAR configuration file, including dependencies and communication types between the runnables.
SymTA/S combines the data from the cost catalogue and the model of the user application, and calculates dedicated metrics, indicating the amount of communication overheads in the overall system.
Different mappings become comparable and a potentially better mapping with reduced overheads can be found. Furthermore the fulfillment of timing constraints can be proven by the scheduling analysis.
Infineon recommends SymTA/S for a model based migration of ECU software to multi-core systems. The model-based approach enables changes of the memory mapping of runnables and data very easily as well as answering "what-if" questions.
“This well-structured approach for mapping software on a multi-core system using SymTA/S can significantly reduce the migration efforts and furthermore the approach scales with the number of cores,” said Jens Harnisch, Tool Line Manager at Infineon Technologies AG.
Even more effectiveness will be achieved by the use of the metrics to develop an automated mapping generator in future work.

09.02.2007: Hanser Automotive: Timinganalyse schafft Klarheit bei ECU, CAN und FlexRay
Artikel in Ausgabe 1-2, 2007:
Über Datenbusse verbundene Steuergeräte sind heute ein unverzichtbarer Bestandteil moderner Fahrzeugelektronik. Fahrzeuge mit mehr als 50 Steuergeräten und verschie-denen, parallelen Datenbussen, die über Gateways verbunden sind, sind keine Seltenheit mehr (s. Titelgrafik). Gleichzeitig steigen die Anforderungen an Systemleistung und Zu-verlässigkeit bei reduzierten Kosten. Eine neue Klasse von Software-Tools unterstützt die Entwickler bei der Optimierung des Designs und Absicherung der Funktionsanforderungen.
