Veröffentlicht Schreibe einen KommentarVeröffentlicht in Automotive, Englische Blogs

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 […]

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Railway

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 […]

FMEA

FMEA – A powerful method, but not for software!

Veröffentlicht 2 KommentareVeröffentlicht in Englische Blogs, Functional Safety, Top 5 eng

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

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 […]

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: 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

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Validation and Verification

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 […]

Reuse scenarios in ISO 26262 (part 1)

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Automotive, Englische Blogs

Why is the reuse of software, hardware, or complete electronic control units a central theme? Two essential aspects are to be considered: the development costs can be reduced significantly, i.e. reuse of components is very attractive in economic terms. But also for security reasons, the reuse of components can offer significant benefits. A control unit, […]
