ISO 26262 Confidence in the use of software tools – A feasible strategy!

FuSa_Automotive

ISO 26262 Confidence in the use of softwar tools: ISO 26262-8 in chapter 11 defines the requirements for software tools that are used in an ISO 26262 compliant software development process. In the practical usage of chapter 11 of ISO 26262-8 many questions often arise, which partly lead to very creative approaches regarding tool qualification.

The following article clarify open questions in this subject and provides answers to the following 3 questions:

  • Why does ISO 26262 require a proof of confidence in the tools used at all?
  • What are the requirements of ISO 26262?
  • How to deal with the ISO 26262 Confidence in the use of softwar tools topic?

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

The non-intrusive measurement of structural coverage!

FuSa__General

The measurement of structural source code coverage is nowadays defined as an important procedure in many functional safety standards. The non-intrusive measurement of structural coverage offers completely new possibilities in the future. For a long time, it was industry-wide consensus that structural coverage should and could only be determined in so-called white-box tests. In many textbooks, the measurement of structural source code coverage is even promoted as an independent test method. The following blog post shows why things are likely to change in the future.
