In recent years the development of automotive embedded devices has changed from an electrical and mechanical engineering discipline to a combination of software and electrical/mechanical engineering. The effects of this change on development processes, methods, and tools as well as on required engineering skills were very significant and are still ongoing(More)
The systematic testing approaches developed within the telecommunication domain for conformance and interoperability testing of communication protocols have been extended and broadened to allow the testing of local and distributed, reactive and proactive systems in further domains such as Internet, IT, control systems in automotive, railways, avionics and(More)
In this paper, we introduce a new test method that enables the systematic definition of executable test cases for testing the continuous behavior of automotive embedded systems. This method is based on a graphical notation for test cases that is not only easy to understand but also powerful enough to express very complex, fully automated tests as well as(More)
Overtone singing, a technique of Asian origin, is a special type of voice production resulting in a very pronounced, high and separate tone that can be heard over a more or less constant drone. An acoustic analysis is presented of the phenomenon and the results are described in terms of the classical theory of speech production. The overtone sound may be(More)
The test of embedded systems is well-supported by a number of different test methods and tools if the system under test displays a discrete behavior. However, for systems with continuous behavior these approaches are not appropriate. Practical experiences with the test of embedded systems in the automotive industry have revealed that testing the continuous(More)
