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 […]
Security is a topic which plays a key role for the success of topics like Internet of Things, Smart Home. If we consider the topic in more detail, it will be realized that it will be worthwhile, to separate the individual topics. It is important to be aware that the boundaries of the separate topics […]
In my daily projects in the automotive and industrial automation industry I’m continually confronted with the following question: How many levels of software requirements have to be written? That’s an interesting question, especially if we take the aerospace industry also into account. Software requirement level are a key topic if you want to improve your […]
ISO 26262 calibrateable Systems are discussed in part 6 Annex C. This blog summarizes important requirements of the standard and shows practice-oriented challenges of software-configurable embedded systems. The use of calibration data in configurable systems offers a lot of advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes […]
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 […]
In the functional safety, there is a method which is always used – the FMEA (Failure Mode Effects Analysis). In particular, on system and hardware level the FMEA supports systematic analysis. There are also variants such as the FMECA and the FMEDA. In this blog post I use only the term FMEA. In project practice […]
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 […]
The quality assurance checks the quality of the product. This is first of all an almost trivial statement. Depending on the definition of the term “product”, however, differentiate the responsibilities clearly. Do we monitor a production process or are we considering the assurance of quality in a software and electronics development? The following blog deals […]
What is the Psychology of Testers? What qualities characterize good people working in the testing area? Well, you can define some criteria: expertise- and methods know-how are sure essential characteristics. In addition, they must have management skills and bring social skills. These are certainly necessary skills. However, it is missing an important point that I […]
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 […]
