Comparison and evaluation of different test design techniques.

B_Validation and Verification

The complexity of technical systems has been increasing for years and there is no foreseeable end to this. The crucial driver of innovation is software. Very powerful hardware in combination with complex software are the basis for trends such as IOT, autonomous driving, Smart Home and human-robot collaboration, to list just a few.

Today, software enables the realization of functionalities with a complexity that was never imaginable with electronics or mechanics alone.

However, this also increases the potential errors in a system. There is no such thing as guaranteed error-free software! A major reason for this is that it is not possible to test an industry relevant software system completely. This is due to the fact that the number of data and control flow paths that can be passed through a software system tends to be infinite. With this background, the following article introduces common test design techniques and evaluates their strengths and weaknesses.

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.

RTCA DO 331 Model-Based Development and Verification in aerospace

FuSa_Aerospace

With the enhancement of the RTCA DO 178B to the RTCA DO 178C, four so-called supplements have also been developed. The RTCA DO 331 Model-Based Development is one of these four supplements and describes the requirements for model-based development and verification in aerospace. The following article provides answers to the following questions:

  • How is the RTCA DO331 structured?
  • What does mean the distinction between specification model and design model?

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

FuSa__General

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 MC / DC Coverage (high SIL / ASIL Level) are required. For good reasons, however, e.g. no path coverage required. These would mean that you would check all the combinations of paths that are possible in a software. This would be an extremely high multiple of test cases compared to MC / DC coverage. Read more

Structural source code coverage and Requirements – Is there any dependency?

B_Validation and Verification

If you are newly engaged in the area of functional safety, then you will encounter fairly quickly the terms “structural source code coverage” and “requirements”. The specification of technical systems by requirements is, of course, also common in non-safety-critical areas. By contrast, the subject structural source code coverage is almost unknown outside safety-critical projects.
In this blog I want to discuss these two methods and the underlying processes. In particular, the question of inter-dependence is exciting. Read more
