The Influence of the System Architecture

Part of the The Springer International Series in Engineering and Computer Science book series (SECS, volume 245)


In this chapter we want to substantiate our previous claim that the system architecture of a target system plays a major role in developing a test methodology for this system. So far, the term “distributed system” was used only in its intuitive meaning; we now give a more rigorous characterization of the system model. We also introduce the notions of event-triggered and time-triggered systems, a distinction which we have found to be very useful in our work on real-time systems [Kop90c, Kop91a]. We then undertake a comparison of these two types of systems, with the result that time-triggered systems offer some significant advantages with respect to testing. The criteria affected by this comparison are Observability, Controllability, and the Test Coverage.
