ISO 25119 Software Development for Tractors and Machinery for agriculture and forestry

Veröffentlicht Veröffentlicht in Englische Blogs, Other FuSaNorms

ISO 25119 Software Development: The norm describes the safety requirements for tractors and machinery for agriculture and forestry. The standard is a sector specific implementation of IEC 61508 and consists of 4 parts. Like other functional safety standards, ISO 25119 specifies various levels of criticality. The standard defines the Agricultural Performance Level (AgPL) QM, a […]

Structural Source Code Coverage – Cost without benefit?

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Functional Safety

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 […]

ISO26262 Safety Case – Success factors: management and traceability!

Veröffentlicht Veröffentlicht in Englische Blogs, ISO26262 eng

The term Safety Case is used in the automotive industry and railway industry (EN50129). The following article focuses on the automotive industry. Project experience shows that the achievement of a proven functionally safe system is complex and extensive. This is particularly true if the development of a product is spread over several companies. I will […]

Requirement and Test Traceability

Requirement and Test Traceability – Any added value?

Veröffentlicht Veröffentlicht in Englische Blogs, Requirements Engineering eng, Uncategorized

Requirement and Test Traceability: Think about the following situation: You are near the end of your safety-related project and you have established traceability between all the project artifacts. In an audit (e.g. Internal Quality Assurance, Customer, External Authority) you have to demonstrate which software requirements are developed from which System Requirements. Each software requirement is […]

Chapter 6.7 of EN50128 and EN50657 support tools and languages defines requirements for software tools that are used in a safety-relevant development process. Project team members in safety projects discuss the content and meaning of this chapter again and again. The following article summarizes the essential requirements and derives a practical guide for use in […]

Requirement completeness using data- and control flow analysis

Veröffentlicht Veröffentlicht in Englische Blogs, Functional Safety

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 non-intrusive measurement of structural coverage

The non-intrusive measurement of structural coverage!

Veröffentlicht Veröffentlicht in Englische Blogs, Functional Safety

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 […]

Functional Safety Basic Standard IEC61508

IEC 61508 – The Functional Safety Basic Standard

Veröffentlicht Veröffentlicht in Englische Blogs, IEC61508 eng

The Functional Safety Basic Standard IEC61508 is often referred to as the mother of all functional safety standards. This standard was introduced in 1998 with the intention of defining cross-industry processes and methods to be used for safety-relevant electrical, electronic and programmable electronic systems. IEC61508 is applied if no industry-specific standards are available for this […]
