Compiler for safety critical software – What needs to be done?

Veröffentlicht am Schreibe einen KommentarVeröffentlicht in DO178 eng, Englische Blogs, Functional Safety

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 […]

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 […]

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 […]
