Shaping Real-Time Systems Engineering of Tomorrow

Automotive systems

Increasing complexity and growing functionality in modern cars challenge project teams. Time to market and cost pressure brings new constraints in the existing design structures. Software infiltrates all systems. Designing robust systems that meet the constraints becomes more and more difficult.

In order to be able to handle all these challenges, INCHRON offers the worldwide unique Tool-Suite to address the automotive needs. The possibility to combine single and multi-core, bus and networks communication system, in one model and to check for load, data consistency or safety requirements is a boost in productivity. That is worldwide unique.

Do you use AUTOSAR?

As partner of the AUTomotive Open System ARchitecture the INCHRON Tool-Suite allows users to work efficiently with the AUTOSAR system model. All features that are needed to describe the software timing behavior and all needed model constructs are available and the import from AUTOSAR arxml files is possible. The huge benefit of working on one database for OEM, supplier and tool provider is the data consistency throughout the project and the fast turnaround times. On the other hand, seemingly small changes of an AUTOSAR configuration parameter often have dramatic consequences on the dynamic system behavior. This is a major disadvantage of abstract modelling the system architecture.

Be always sure your system works correctly! Add the Tool-Suite into continuous integration systems!

Without doubt an important driver of AUTOSAR is the integration application software from different Tier-2 suppliers into a single ECU. Such collaboration project has very high technological and organizational risk to fail or at least a high risk exceeding the budget. Many development project leaders can tell you a thing or two about timing and performance problems in late stages of AUTOSAR projects. Our tools and timing methodology forces you to handle with the necessary care and technical depth.

Be a good engineer: Get rid of implicit or unknown timing requirements with our Tool-Suite!

Driver Assistance Systems

"Up to now we identified timing and performance problems only during series development. Next time we will do this systematically right from the start - already in the concept phase."

CAN, FlexRay Ethernet. What will be the next challenge?

One of the most challenging topics in the automotive industry are the different communication mechanism used. Having a tool that allows modelling of complex systems in an easy way and performing fast and reliable analysis of all the different standards is a key in developing robust architecture. Dynamic behavior can influences a system from one part to another. To avoid complications in later stages, a model that reflects this behavior should be created in early design stages. The INCHRON Tool-Suite offers the perfect solution for these kinds of new challenges.

Advanced driver assistance systems

All renowned automotive manufacturers have already announced new customer functions for advanced driver assistant systems in order to achieve a competitive advantage. This increasing functionality leads to ECUs with dedicated hardware and several multi-core processors. A huge amount of date from cameras, radars and ultrasonic sensors has to be distributed via standardized or proprietary buses. Different time bases (data rates) of these sensors are a challenge for the design of dynamic software architectures in general. In particular, for sensor fusion the date of these and other sensors has to be synchronized. This results in complex data flow event chains over several cores, buses and processors. Designing such complex architectures in a trial and error manner does not work anymore.

Since 2007 our Tool-Suite supports the visualization and requirement evaluation of complex event chains. It is a necessary prerequisite to design robust architectures and crucial for project success.

Powertrain

At least two dominant time bases (time triggered and crank shaft) and increasing functionality demands everything architects got. In dependency of the engine speed the net execution times of software is changing. Altogether this results in a high and varying interrupt rate, high peak processor load, and a dynamic system behavior hard to predict.

Gerhard Wirrer, Continental
Senior Manager

"The simulation with our simplified model is surprisingly precise. (only few percent deviation to real behavior, every problem found in real system has been reproduced in simulation)"

In addition the migration to multi-core increases the technical complexity dramatically. Many new challenges have to be solved: What is the best mapping of software components to cores? How can I achieve a sufficient load balancing? What is a sufficient concept and implementation for a time and load efficient inter-core communication?

Our Tool-Suite has been developed to find the best solution!

Senior Technical Expert

"chronSIM's realistic simulation provides sufficient means to simulate the scheduling behavior and core interaction in a multi-core system offering valuable insights concerning the partitioning of the application SW."
