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 such as ISO26262 (car), EN50128 […]
In the last blog (June 2017), I explained the principle of Freedom of Interference. The example used was based on the automotive industry and the ISO26262. Now I would like to consider Freedom of Interference with respect to the industry sectors railway, aviation and automotive and share my industry experiences with you.
The proof of a 100% structural source code coverage is required by almost all functional safety standards (IEC61508, ISO26262, DO 178C, etc.). In the individual SIL / ASIL levels, only the type of source code coverage is differentiated. Essentially, the Statement Coverage (low SIL / ASIL Level), the Branch Coverage and the MC / DC […]
IEC 61508, ISO26262, DO 178C, ISO 25119: Have you ever encountered these abbreviations in your professional life? If so, there is a high probability that you are already implementing functional safety projects in your company or that you are entering the market in the near future. Perhaps you have already made the experience, or at […]
In my daily projects in the automotive and industrial automation industry I’m continually confronted with the question of how many levels of software requirements have to be written. That’s an interesting question, especially if we take the aerospace industry also into account. Therefore, I want to highlight in this blog post this topic a bit […]
