16.04.2013: Symtavision adds Ethernet timing analysis to SymTA/S
Targets automotive industry applications and integrates seamlessly with existing SymTA/S analyses for CAN, FlexRay and AUTOSAR-based ECUs
Symtavision has announced the addition of Ethernet timing analysis to its SymTA/S tool for the design and verification of embedded real-time systems. The new Ethernet timing analysis targets the automotive market and integrates seamlessly with the existing in-vehicle network timing analyses for CAN and FlexRay as well as with scheduling analysis for AUTOSAR-based ECUs.
“We have added Ethernet timing analysis to SymTA/S in response to the automotive industry’s introduction of Ethernet to meet growing in-vehicle network bandwidth requirements,” said Dr Marek Jersak, CEO of Symtavision. “Over the past two years, we have collaborated tightly with premium automotive OEMs and leading universities to create an Ethernet timing analysis solution that enables OEMs and Tier 1 suppliers to plan, optimize and verify timing when introducing Ethernet. A unique capability of Symtavision’s solution is the integration of our new Ethernet timing analysis with our well-established analyses for CAN, FlexRay and AUTOSAR-based ECUs. This enables end-to-end timing analysis for distributed functions via Ethernet, as well as connecting Ethernet to legacy CAN and FlexRay networks via gateways”.
The SymTA/S Ethernet analysis capability focuses on timing design and verification for both standard IP Ethernet (Layer 3) and Audio Video Bridging (AVB). The SymTA/S Ethernet model covers entire Ethernet networks including ECUs, switches, ports, messages, PDUs and links which can be directly combined with other bus systems like FlexRay and CAN, in addition to white box or black box gateways. Furthermore, the model supports the co-existence of internal ECU scheduling and Ethernet communication, including any triggering and synchronization requirements. The model can also be scripted for easy tool chain integration and model transformation of existing Ethernet communication matrices.
The SymTA/S Ethernet analysis capability covers different communication priorities, MTU sizes, scheduling strategies, and transmission rates as individual rates per port as well as automatic end-to-end hop resolution, static routes, traffic classes, and single cast, broadcast and multicast communication, including multiple hops over switches for star or other topologies. Statistical metrics are provided for load and load-over-time of each port or on a switch as well as buffer fill levels as absolute or as over-time values for each port and switch. In addition, response times are provided for each Ethernet message and data communication paths can be observed for different end-to-end scenarios. Each result can be validated against constraints and the timing can be debugged individually through Gantt chart visualization, including point-of-interest functions such as deadline violations.

Symtavision US offices are located in the Liberty Center, Suite 200, 100 West Big Beaver Road, Troy MI 48084.
25.02.2013: Launch of SymTA/S 3.3 features significant new timing analysis and design capabilities
Timing analysis support added for FleyRay Dynamic Segment, CAN-FD and Buffer Fill Level analysis, alon with new design features including a Customizable Wizard Framework and powerful Drag-and-Drop Support
Symtavision has launched SymTA/S 3.3, a major new version of its award-winning system-level tool suite for planning, optimizing and verifying embedded real-time systems. SymTA/S 3.3 features significant new timing analyses including support for FlexRay System Distribution, the new CAN-FD standard, Buffer Fill Level analysis for COM and Gateways, as well as enhanced Gantt chart customization. Major improvements to the design features of SymTA/S 3.3 include a new Customizable Wizard Framework and improved drag-and-drop functionality providing resolution of dependencies. At the same time, Symtavision has announced TraceAnalyzer 3.3, a new version of its powerful solution for visualizing and analyzing timing data from both measurements and simulations which seamlessly integrates with SymTA/S.
Commenting on the launch of SymTA/S 3.3, 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.”
New Analyses
With the launch of SymTA/S 3.3, the SymTA/S System Distribution analysis framework is extended with support for FlexRay covering both Static and Dynamic Segments, with the latter supporting cycle multiplexing for FlexRay 2.x frames. With the addition of this capability, users are now able to analyze end-to-end scenarios from sensors to actuators that include communication via FlexRay.
SymTA/S 3.3 also extends the existing CAN timing analysis capability with integrated support for the new CAN-FD standard. To perform CAN-FD analysis only a few scheduling-relevant parameters are required including CAN-FD bus speed, which frame is being sped up and what payload is being transmitted via the frame. Everything else is transparent to users as SymTA/S 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.
With the new Buffer Fill Level analysis, which provides the fill level in bytes for COM-layer send buffers and the number of frames stored in them, users can get an overview of the buffer sizes required and check them against constraints. SymTA/S error-flags buffers that exceed their maximum fill level.
New Gantt Grouping and Filter Management capabilities in SymTA/S 3.3 provide users with a significantly improved overview of Gantt charts. The 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 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.
Visitors to the Symtavision Embedded World booth (Hall 4, Stand 327) will also be able to preview SymTA/S Ethernet analysis focusing on AVB and IP Ethernet (Layer 3). The model covers entire Ethernet networks including ECUs, switches, ports, messages, PDUs and links. The analysis covers different communication priorities, MTU sizes, scheduling strategies, and transmission rates, as well as automatic end-to-end hop resolution, static routes, traffic classes, broadcast and multicast.
New Design Capabilities
Both SymTA/S 3.3 and TraceAnalyzer 3.3 include a new Customizable Wizard Framework, enabling users to create a customized graphical interface through scripting, which 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 Symtavision 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 drag-and-drop functionality has been enhanced in SymTA/S 3.3 to enable dependencies to other elements to be resolved on re-mapping, such as moving a task from Core1 to Core 2. The capability enables all dependent objects to be considered and re-mapping suggestions to be automatically generated. It also considers different recursion levels which represent the 'deepness' of mapped children, referenced elements and even dependencies to parents.
20.09.2012: Symtavision launches SymTA/S 3.2 and TraceAnalyzer 3.2

19.06.2012: SymTA/S supports ECU software development on new multicore AURIXTM automotive microcontrollers from Infineon
Infineon/Symtavision extend partnership for model-based timing design and verification of multicore software
Symtavision, the global leader for timing design and timing verification for embedded real-time systems, has announced that SymTA/S supports the timing design and verification of embedded software developed for the new multicore AURIXTM microcontroller family from Infineon Technologies.
“The performance requirements of embedded applications in the automotive domain increasingly demand the implementation of specialist multicore MCUs like AURIX in order to achieve the desired features at a reasonable cost,” said Dr. Marek Jersak, CEO of Symtavision. “However, regardless of whether designers are developing software for the AURIX family from scratch or migrating existing software from a single core ECU, the process raises some interesting and difficult challenges.”
As Symtavision’s partner, Infineon recommends SymTA/S for model-based development of automotive ECU software for multicore systems. Multicore platforms offer new opportunities and advantages and also extend the design space for software architectures like runnable to core mappings. The decision as to which runnables should be mapped to which cores and which data containers lie in which memories, is strongly influenced by communication overheads. Communication between the cores, realized through Inter OS-Application Communication in AUTOSAR 4, and also the communication with external memories can lead to significant additional execution times for runnables. These communication overheads can easily eat up the performance improvements expected from a multicore ECU. The question is: how big are these overheads and how can they be reduced? SymTA/S provides the answers, efficiently facilitating the memory mapping of runnables and data as well as answering any necessary “what-if" questions. This helps software designers to produce a software architecture of good quality and to utilize multicore platforms efficiently.
“Using the well-structured SymTA/S approach to map software on the AURIX multicore microcontrollers can significantly reduce development and migration efforts,” said Jens Harnisch, Tool Partner Manager at Infineon Technologies AG. “Furthermore the SymTA/S approach scales with the number of cores.” Featuring up to three independent 32-bit TriCoreTM CPUs, the AURIX MCUs from Infineon have been designed to meet the exacting ISO 26262 safety requirements for automotive applications while significantly increasing performance. The modular design and memory approach of AURIX provide the scalability that customers increasingly demand and its in-built encryption technology is designed to meet the upcoming security requirements of next-generation vehicles. The AURIX family is ideally suited to powertrain applications including hybrid and electric vehicles as well as safety applications such as steering, braking, airbag and advanced driver assistance (ADAS) systems. With AURIX, both powertrain and safety applications can be controlled using a single ECU.
22.05.2012: Symtavision appointed a Contributing Member of ARTOP
Symtavision, the global leader for timing design and timing verification for embedded real-time systems, has announced that it has been appointed as a Contributing Member of the ARTOP (AUTOSAR Tool Platform) User Group.
ARTOP is an Eclipse-based infrastructure platform implementation of common base functionality and core features for development tools that are used to design and configure AUTOSAR-compliant systems and ECUs. The aim of ARTOP is to improve the quality and interoperability of AUTOSAR development tools and help eliminate the time lag between the release of new versions of the AUTOSAR standard and the availability of development tools that support the new specifications. Development is organized by the Design Members of the ARTOP User Group, which includes BMW, Continental and Peugeot/Citroen, and implemented using a transparent, community-based approach by the group of ten Contributing Members including Symtavision. ARTOP, including its source code, is available free of charge to all AUTOSAR members and partners.
“Our appointment as a Contributing Member of the ARTOP User Group recognises both our leading role in the development of AUTOSAR-compliant systems and ECUs and emphasizes our commitment to designers by improving the common base for AUTOSAR development tools,” said Dr. Kai Richter, CTO of Symtavision. “We have benefitted considerably from using ARTOP to minimize our development costs for non-competitive functionality and freeing development resources to concentrate on our competitive advantage. As a consequence, we have developed considerable functionality around ARTOP which we expect, as a Contributing Member, to integrate into future releases for the benefit of other tool developers.”
20.04.2012: SymTA/S supports ISO 26262 compliant design of mixed-criticality automotive electronics systems
The SymTA/S methodology meets primary ISO 26262 requirements for reliable coverage of failure and error-free timing scenarios, and overcomes inherent safety vs. efficiency conflicts
Symtavision, the global leader for timing design and timing verification for embedded real-time systems, has announced that SymTA/S supports the design of ISO 26262 compliant mixed-criticality automotive electronics systems. The SymTA/S methodology overcomes the inherent safety versus efficiency conflicts, especially when ‘freedom from interference’ must be realized between software partitions with different criticality levels. The SymTA/S methodology uniquely meets the primary ISO 26262 requirement to provide reliable coverage for failure and error-free scenarios by undertaking timing analyses to optimize and verify the ECU software schedule. Crucial to this is the ability to use SymTA/S timing analyses to select configurations for OS services such as watchdog timeouts and timing protection budgets rather than simply react to timing failures while the target system is running.
“Designing for ISO 26262 is an extremely hot topic” said Dr. Marek Jersak, CEO of Symtavision. “With the advent of mixed-criticality ECUs in automotive electronic systems, the established design patterns for building ECU schedules are unsuitable as they trade off efficiency for safety. Using SymTA/S for the design of ISO 26262 compliant mixed-criticality automotive electronic systems allows ECU schedules to be created, analyzed, optimized and verified that are not only safe and certifiable but also efficient.”
To build ISO 26262 compliant ECU schedules that are both safe and efficient, the SymTA/S methodology draws on a combination of the established RMS (Rate Monotonic Scheduling) and the recently proposed CAPA (Criticality As Priority Assignment) timing schedule strategies coupled with procedural guidelines, based on extensive SymTA/S timing analysis, on how safety can be verified and efficiency determined. RMS, which is currently used extensively in the industry, yields compact, resource-efficient pre-emptive timing schedules for AUTOSAR and OSEK, but it cannot cope with mixed-criticality requirements as priority is given to tasks with the shortest cycle time without reference to safety requirements and criticality levels. On the other hand, a CAPA strategy can ensure the necessary ‘freedom from interference’ between tasks that ISO 26262 demands but this comes at the cost of a significant reduction in resource efficiency.
Using timing analysis data from SymTA/S, the ISO 26262 compliant design methodology enriches key aspects of both the RMS and CAPA schedule design patterns with guidelines on how to select priorities, when and how to use Watchdogs or Timing Protection, and when the software architecture needs to be adapted in terms of cycle times and runnables-to-task mapping. Furthermore, SymTA/S reliably covers error-free and failure scenarios of various kinds, and hence provides evidence that the software and safety architectures are suitable.
“Already proven on real-world ISO 26262 compliant mixed-criticality automotive electronics systems, the SymTA/S is an invaluable aid for software architects in the planning phase of ECU software integration,” concluded Dr. Marek Jersak, CEO of Symtavision. “The ability to select appropriate measures to ensure efficiency and certifiability as well as deliver safety at the lowest possible hardware cost is crucial to ISO 26262 ECU schedule design.”

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.”

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.
