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

FuSa__General

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 used during the development. (Refer to tool qualification blog 1 and blog 2) Such functional safety standards are ISO26262 (car), EN50128 (rail), IEC61508 (automation, general) or DO178C (aerospace).  The compiler plays a special role here. On the one hand, it is the central tool for any development. On the other hand, the measures proposed in the standards can not be fully applied in practice. The blog shows a process from the aerospace industry how to use compiler for safety critical systems. This process can highly be recommended for other industries. Read more

Implicit Testing – A good idea (Part 2)?

B_Validation and Verification

In the first part of the blog I defined the term Implicit Testing and discussed root causes for the need of implicit tests. Now, in the second part I will focus on the disadvantages of such tests and on possible solution approaches with the goal to avoid these disadvantages. Read more

Economical considerations on requirement reviews!

A_Requirement Engineering

Quality costs money! Many can probably agree with this statement. Anyway, it is difficult to refute the statement, as it is very generic.
At the same time very often the simplistic conclusion is drawn, that any quality measure within the software development process is just expensive.
I want to take a closer look with the following blog. As an example for quality measures I will take the requirement review. These reviews are required by all the functional safety standards. Read more
