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 […]

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 […]

Structural source code coverage and Requirements – Is there any dependency?

Veröffentlicht am

If you are newly engaged in the area of functional safety, then you will encounter fairly quickly the terms “structural source code coverage” and “requirements”. The specification of technical systems by requirements is, of course, also common in non-safety-critical areas. By contrast, the subject structural source code coverage is almost unknown outside safety-critical projects. In […]

Software requirement level

In my daily projects in the automotive and industrial automation industry I’m continually confronted with the following question: 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. Software requirement level are a key topic if you want to improve your […]
