With the enhancement of the RTCA DO 178B to the RTCA DO 178C, four so-called supplements have also been developed. The RTCA DO 331 Model-Based Development is one of these four supplements and describes the requirements for model-based development and verification in aerospace. The following article provides answers to the following questions: How is the […]
Many people associate with the implementation of functional safety, a lot of formalism, and unnecessarily extensive documentation and many processes with a high proportion of theoretical framework. And yes, such projects are existing very often and in every industry. My experience shows that such projects are not very powerful when measured by the real implementation […]
With the enhancement of the RTCA DO 178B to the RTCA DO 178C, four so-called supplements have been developed. These supplements of DO 178C define the conditions under which modern software development methods can be used in aerospace. If you look at the history of the RTCA DO 178, you will notice that changes to […]
RTCA DO 178C – The Myth! As early as 1980 there were first considerations in aerospace how to develop software safely and as accurately as possible. These considerations have led to the development of a standard that is widely respected far beyond software. Currently in the version RTCA DO 178C. The standard is used in […]
The need for security protection measures in the Office IT environment is obvious since years. Firewall, virus scanner, encryption of data: Office IT is no longer thinkable without these aspects. On the other hand, security for embedded systems is relatively new. These systems are already vulnerable to possible malicious attacks. For a long time there […]
Requirement Engineering Embedded versus IT: If you analyses the book market, publications or conferences on requirements management and Requirement Engineering, you will find that more than 90% consider requirements engineering from the point of view of IT software systems. There are very few publications that look at the topic from the perspective of embedded systems. […]
Requirement Engineering theory: In most of the requirement engineering publications, the focus is on management aspects. The collection and management of requirements is discussed extensively. In the following blog I discuss important aspects which are not sufficiently considered in the RE theory. I start with the definition of Requirement Engineering in the book “Requirements Engineering […]
The compiler is the central “tool”, which is required for every software development. It forms the link between the human-readable high-level source code (e.g., C and C ++) and the machine code, interpretable for the hardware processor. For the development of safety critical software according to relevant functional safety standards special requirements apply for the tools […]
In the blog post ISO26262: Freedom from interference – What is that?, I explained the principle of Freedom from Interference. The example used was based on the automotive industry and the ISO 26262. Now I would like to consider Freedom from Interference with respect to the industry sectors railway, aviation and automotive and share my […]
ISO 26262 Freedom from interference : There are four essential measures in the development of safety-critical systems. Design of safe systems Measures to minimize random hardware errors Measures to minimize systematic hardware and software errors Organizational measures (management of functional safety) Particularly in the design of safe systems, the principle of Freedom from interference is […]
