INCHRON is an active member of the AUTOSAR consortium and has a strong footprint and proven track record of success in the automotive industry.
Intrusive vs. Non-Intrusive Tracing
Trace information serves as the basis for analyzing the root causes of a wide variety of problems that are revealed by system tests on the target hardware. When it comes to the mechanism of trace generation and recording, there are basically two approaches with their respective pros and cons: intrusive tracing and non-intrusive tracing.
Read more about the pros and cons of both tracing methods in the context of embedded real-time systems, and how you can benefit from non-intrusive on-chip tracing for comprehensive timing analysis on the Infineon AURIX platform.
Auto-Testing Timing in Your CI/CD Pipeline
Many teams use continous build / continous deployment (CI/CD) pipeline in their development workflow. Timing requirements can automatically be checked in the test pipeline. chronVIEW is easily integrated using a Docker container.
Development of Safety-Critical Systems: The Timing Aspect
Timing issues that remain undetected or unresolved in a safety-critical system compromise safety – to an extent and in a way that is rarely predictable. Learn how to master the complexity of the timing aspect and how to perform a comprehensive timing analysis by using the INCHRON Tool-Suite and the Infineon AURIX MCDS on-chip trace feature.
Infineon AURIX: Unlocking the Potential of Multi-Core Timing Analysis
Infineon’s Multi-Core Debug Solution (MCDS) provides non-intrusive, parallel trace output that is a very powerful tool to analyze and debug AURIX(TM)-based real-time systems in full operation. Learn how to maximize its benefit for comprehensive timing analysis.
End-to-End Performance Optimization for Autonomous Driving
High quality and safety-critical requirements, aggressive time to market schedule, and increasing technical and organizational complexity are fundamental constraints for autonomous driving. Using the most proven development methods and tools is the key to success. But which aspects are crucial?
Event Chains in Mixed AUTOSAR Classic and Adaptive Platforms
Systems comprising devices based on AUTOSAR classic and adaptive platforms will soon be present in every major vehicle. End-to-end timing along the event chains will be a critical key design element.
Perfection in Real-Time: A Key Enabler for Autonomous Driving
Autonomous driving is the most disruptive innovation in the automotive sector ever. It is going to fundamentally change the way we travel by car. Major technological challenges, however, have yet to be overcome to enable fully autonomous driving.
Simulation of Safety-Critical Automotive Control Systems
Electronic control units (ECUs) for safety-critical systems have been successfully developed for decades. In recent years, ADAS and autonomous driving have resulted in an increasing number of software components and microprocessor cores in such systems.
But what does a methodology look like, that considers different aspects of timing in complex safety-critical systems in an efficient, practical and well-proven way?
Autonomous Driving: A Real-Time Challenge
For today’s advanced driver assistance systems (ADAS), about 50 time critical event chains have to be jointly optimized – all across the system, from sensor to actuator, including embedded control units (ECUs), buses, gateway ECUs, hypervisors, and operating systems – to meet all real-time requirements.
When it comes to fully autonomous driving, well above 1000 time critical event chains have to be jointly optimized. This is not something that could be done manually anymore. This is where the INCHRON Tool-Suite comes in handy, with model-based simulation and trace-based analysis & test.

Virtualisation for Safe Software Architectures
In the automotive industry, the trend is towards integration of an increasing number of features, that are being developed by an increasing number of independent tier-2 suppliers, on central controllers. Any change wrt. any feature might negatively impact the whole system, such that changes affecting just a single component may result in the need to perform another full verification run on the whole system …

The objective of a Volkswagen prototyping project is to reduce the strongly increasing efforts for test and re-certification. Software encapsulation is intended to enable tier-2 suppliers to independently verify their respective software component. A hypervisor provides virtual machines (VMs) with well separated memory regions and run time supervision. Such an architecture provides a high degree of flexibility: Each VM can be developed independently of others. Applications of the same ASIL level can be combined into a single VM. We showcase best practices for the design of a hypervisor based architecture and analyse event chains with the help of tracers.
Architecture Variants of Safety-Critical Real-Time Systems
More and more embedded systems are considered to be safety-critical and are quite often characterised by a combination of high availability requirements and hard real-time requirements. In the automotive industry, safety features and driver assistance features are both falling into this category. In case real-time requirements are not being paid attention to right from the beginning, costly changes of system / software / hardware architecture will be among the consequences …

In the joined work, an example for a consistent approach is being discussed, covering safety analysis to functional architecture to technical architecture. Safety-critical event chains are being identified, end-to-end real-time requirements are being assigned, and time budgets are being derived – as early as in the functional architecture. Based upon the given functional architecture, possible technical architecture variants are being developed, the respective real-time behavior is being simulated, and finally the variants are being assessed in a systematic way.
