Structural Source Code Coverage – Cost without benefit?

FuSa__General

Structural Source Code Coverage: Are you working in software projects where functional safety is becoming more and more important? The use of IEC 61508, ISO 26262 or a comparable standard is around the corner or you are already in the middle of such a project? In these cases you have probably already encountered the term Structural Source Code Coverage. Many people often consider the achievement of structural coverage to be equivalent to a very high testing effort and they doubt whether the costs and benefits of this topic are in a reasonable ratio.

Requirement completeness using data- and control flow analysis

A_Requirement Engineering

Carrying out a data- and control flow analysis is required in almost all functional safety standards (ISO 26262-6 Table 7 Measures 1f/g, DO 178C Table A-7 Measure 8 and EN 50128, EN 50657Table A19 Measures3/4). In comparison to other measures, the data and control flow analysis causes a lot of questions, when it comes to the real execution. This is mainly since the technological capabilities have so far been lacking to carry out such an analysis.

The new non-intrusive system observation technology (www.accemic.de) offers the possibility to prove data- and control flows by tests. Therefore, a systematic check can be performed in future to prove the functional completeness of the requirements. Read more

Importance of Tool Qualification in the FuSa (part 1)!

FuSa__General

Importance of Tool Qualification : Many companies and project teams that carry out projects for the first time in the field of functional safety have the impression that the tool qualification is critical to success and involves a great deal of effort. Although the Importance of Tool Qualification is justified, the subject is interestingly often given an not adequate attention.
This effect is very similar in several, very different industries such as aerospace, automotive or industrial automation.
The following article (part 1) therefore deals with this topic. Part 2 can be found here: Tool qualification – The phantom pain of functional safety (part 2)! Read more

EN 50128 configurable Systems – The solution?

FuSa_Railway

EN 50128 configurable Systems: Chapter 8 of EN 50128 specifies the requirements for systems that are configured by application data or application algorithms (EN 50128 configurable Systems). This blog summarizes the essential requirements of the standard and the practice-oriented challenges of software-configurable embedded systems.
At the first glance the configurability offers only advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes in the application data to the desired behavior. The source code of the generic software is not to changed. A multiple reuse is possible thereby. If it is well done, even the unit tests should be reuseable, without any change. The EN 50128 also states that proven, generic software can be reused repeatedly in this way. These are important advantages. Read more
