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 […]

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

Veröffentlicht 1 KommentarVeröffentlicht in 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 special requirements apply for the tools […]

Compiler für sicherheitsrelevante Software – Was ist zu tun?

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Deutsche Blogs, Funktionale Sicherheit

Der Compiler ist DAS zentrales „Tool“, welches man in jeden Software Produktentwicklung benötigt. Er bildet das Bindeglied zwischen der vom Menschen gut lesbaren Hochsprache (z.B. C und C++) und dem für den Hardwareprozessor interpretierbaren Maschinencode. Für die Entwicklung sicherheitsrelevanter Software nach entsprechenden Funktionalen Sicherheitsstandards wie ISO26262 (Auto), EN50128 (Bahn), IEC61508 (Automatisierung, Allgemein) oder DO178C (Luftfahrt) […]

Challenges when determining the structural source code coverage on the target!

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Functional Safety

Structural Coverage Target: 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 […]

IEC 61508, ISO26262, DO 178C, ISO 25119: Have you ever encountered these abbreviations in your professional life? If so, there is a high probability that you are already implementing functional safety projects in your company or that you are entering the market in the near future. Perhaps you have already made the experience, or at […]

Implicit Testing – A good idea (Part 1)?

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Validation and Verification

In larger safety-critical projects, quite often I hear the following statement: „Well, the Requirement A is indirectly or implicitly proven with the test XY!“ Do you know this sentence as well? Have you ever experienced what can happen in late project phases when you have tested many requirements indirectly? The blog defines the term in […]

Fault Injection Test in ISO 26262 – Do you really need it?

Veröffentlicht 6 KommentareVeröffentlicht in Automotive, Englische Blogs, Top 5 eng

Fault Injection Test: The ISO 26262 defines the fault injection test as a test method for the system integration and unit test level (ISO 26262-4 [System] Tables 5, 8, 10, 13, 15, 18; ISO 26262-5 [Hardware] Table 11; ISO 26262-6 [software] tables 10, 13). This method has certainly a large part in the implementation of […]

Testing of platforms: A challenge!

Testing of platforms are challenges! Do you develop platforms in embedded systems in order to offer more customer solutions without having to make a completely new development for each customer project? Or do you have used an embedded operating system in order to develop your application as independent as possible from the hardware? For the […]

Management aspects of testing

Management aspects of testing : Often Testing is a hassle topic. Time is short. The number of unmanageable tests, review and analysis is high. Employees are not really motivating for the subject. The technical resources are not sufficient. In the opinion of management, the expected result is already predetermined: no mistakes! Do you know this […]
