Testing of embedded control systems with continous signals
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 alike. With the application of these testing principles it became apparent that the testing of systems with continuous systems is different to that of discrete systems. Although every continuous signal can be discretized by sampling methods (and hence mapped to the discrete signal paradigm), abstraction and performance issues in this setting become critical. This paper investigates the different options to support tests of embedded control systems in the framework of TTCN-3.
