Safety Analyses According to ISO 26262 at a Glance

tudoor academy is back with an interesting topic: safety analyses. In this webinar, we introduce the main types of safety analyses and explain their role in the safety-related development process as per ISO 26262. Certain safety analyses such as Failure Mode and Effects Analysis (FMEA) are already commonplace in development projects in the automotive industry. However, in safety-related projects compliant with ISO 26262, safety analyses must be performed at the system, hardware, and software levels. Several analysis techniques must be applied and suitably combined to achieve these objectives. Furthermore, analysis results must be incorporated into and reconciled with other work products. Frequently used analysis methods are FTA (Fault Tree Analysis) and FMEDA (Failure Mode Effects and Diagnostic Analysis) along with FMEA. This tudoor academy webinar outlines these analysis methods and focuses on their application in compliance with ISO 26262.

Formal Requirements – Least Heeded When Most Needed?

Learn what formal requirements are, why we need them, and what they enable for software testing.
Functional requirements are vital when it comes to software quality. They form the basis for a common understanding of the product being developed. These requirements are often written by different stakeholders in natural language and in a non-standardized way. But natural language carries the risk of being open to interpretation.

In this webinar, we discussed whether or not formal requirements are the answer to this problem. We also had a closer look at how formal requirements can improve test process automation and cloud readiness.

Static Model Analysis for AUTOSAR Models

In this webinar, we gave a practical demonstration of how the MES Model Examiner® (MXAM) can be used for AUTOSAR models in TargetLink®/EmbeddedCoder® to ensure quality in static model analysis.
Over the past 20 years, AUTOSAR has become one of the most important standards for developing software components in the automotive industry. Since then, the model-based approach has dominated software development projects and modeling and code generation tools like Simulink®/TargetLink®/EmbeddedCoder® have improved integrated AUTOSAR support.
However, the quality of the model is a decisive factor for the quality of the generated software components or runnables. Therefore, guideline checking and static analysis tools such as the MES Model Examiner® (MXAM) are indispensable in AUTOSAR-related toolchains.

Does Safe Also Mean Secure Software? - Automotive Safety & Cybersecurity

In the past, cars only had to do one thing: drive. Nowadays, one of the biggest challenges facing the automotive industry is the transition from hardware-based product to software-defined vehicle. More and more OEMs are becoming software companies, as software becomes the main area of development in cars. Cars are becoming computers on wheels. New technological capabilities such as over-the-air updates and the integration of personal digital devices are placing additional demands on IT security (cybersecurity). Industry standards such as ISO 21434 "Road vehicles - Cybersecurity engineering" provide solutions.

But where do to the existing safety standards and the additional security standard come into automotive software development? What impact
does cybersecurity have on the model-based development and quality assurance of automotive software?

Our upcoming webinar tackles these questions. We will give an initial overview of the similarities and differences between ISO 21434 (Cybersecurity), ISO 26262 (Functional Safety), and ISO 21448 (SOTIF), and how they complement each other.

Secure controller software is the key to ensuring that all these systems are safe. For these reasons, the automotive industry has established safety standards and reference processes for model-based software development, such as ISO 26262 and the TargetLink Ecosystem, to safeguard the controller software. In this webinar, we will show you what contribution MES’ tools make to efficiently securing highly complex software in the TargetLink Ecosystem. Safe driving, safe journey!

Agile Model-Based Software Development & Agile Model Testing

Developing embedded software according to agile principles, while at the same time meeting functional safety standards: in this webinar we will show you how it can be achieved. We will take a closer look at the current state-of-the-art approach for developing embedded applications namely model-based software development. In the automotive industry, defined processes and methods along with established toolchains ensure compliance with the high standards and functional safety requirements for the developed applications. The best practices of general software development, on the other hand, recommend overcoming strict waterfall process models and promoting agile methods to better cope with real-world challenges such as unclear requirements or last-minute specification changes. Introducing agile methods into the process-driven software development of safety-relevant functions can make them more efficient and robust in the face of precisely those real-world challenges without compromising safety standards. Automatically controlled toolchains, e.g. using Jenkins, take over a large part of the inspection and test routines for quality assurance in compliance with ISO 26262. In this webinar, we will look at concepts and best practices for agile model-based software development in compliance with ISO 26262.

What Model Metrics Have to Do With Model Quality

In model-based development, the quality of models is the essential factor for good code. Static model analysis is of fundamental importance for this quality assurance and the application of modeling guidelines is well established industrywide. Modeling guidelines are not the only relevant aspect for compliance with the required design principles because a large number of aspects can only be improved in the context of model properties. Model metrics are very well suited for this purpose. In this webinar, we will show you which model metrics can significantly improve model quality in terms of the design principles, provide ways to aid interpretation and best practices for applying these metrics, and show you how the model quality improves.

MBD: 10 Problems Solved

Model-based software design (MBD) is a software development method that has been used since the 1990s, especially for the development of embedded systems. MBD rapidly expanded with the introduction of efficient automatic code generation, aided by tools such as Embedded Coder® and TargetLink®. When implemented properly, MBD can help with generating higher quality code more quickly and can also help to reduce costs.
However, poor processes, tools, and execution can also result in poor quality code that costs more and takes longer to create. This webinar addresses ten problems associated with software development and proposes solutions to these issues.

5 Views of the Product Quality of Your Software

Software development is complex. It is usually not possible to make precise ad hoc statements about the current product quality. This leaves developers working from their intuition and the danger is that areas where action is needed may be identified too late. However, it is possible to automatically collect and evaluate KPIs during the development process in order to better assess risks.

The basis for this are quality models in compliance with ISO 25010, which allow structured calculation and aggregation of quality data. One tool that works with this method is the MES Quality Commander® (MQC). MQC calculates and visualizes the current quality status. MQC also helps to identify the need for action at an early stage to get to the root of the matter. We invite you to take a look at a software product from different perspectives with us in this free webinar so that you can form your own impression.

What if ... 50% Reduction in Effort?

Is the embedded automotive software industry reaching a breaking point?

Some observations:

  • Many companies have multiple openings for software/control developer
  • Economic forecasts are indicating 100s of thousands of projected unfilled technical openings in the upcoming years
  • Automotive software content per vehicle on high end vehicles (100 million lines of code) already require about 3-4 times the size and hence complexity of aerospace software on a plane
  • With emerging applications such as ADAS, electrification, autonomous, the quantity of automotive software is rapidly increasing
  • Expensive product recalls due to software errors are rising

With all this pressure on the embedded software development industry, would reducing the effort to generate high quality software by up to 50% in select process steps be beneficial?

MES Model & Refactor® (MoRe) – Simplify your modeling.

This new tool speeds up and simplifies the creation and editing of Simulink® models and can be used for all Simulink® versions from R2009b and later. After selecting specific elements (signals, blocks), actions are offered that automate frequently used operations – especially operations that consist of several substeps. Performing these tasks manually can often be laborious or time-consuming and thus error-prone. An example of this is the addition of signals across multiple hierarchy levels. This kind of additional input signal can now, for instance, be added from an upper level to a subsystem in a low level with a single action. This presentation will introduce a number of these actions and show how this tool makes working with Simulink® models – especially big models – easier, faster, and more reliable.
