ABSTRACT
Embedded systems are becoming increasingly common in our everyday lives. As technology progresses, these systems become more and more complex. Designers handle this increasing complexity by reusing existing components. At the same time, the systems must fulfill strict functional and non-functional requirements.
This thesis presents novel and efficient techniques for the verification of component-based embedded system designs. As a common basis, these techniques have been developed using a Petri net based modelling approach, called PRES+.
Two complementary problems are addressed: component verification and integration verification. With component verification the providers verify their components so that they function correctly if given inputs conforming to the assumptions imposed by the components on their environment.
Two techniques for component verification are proposed in the thesis. The first technique enables formal verification of SystemC designs by translating them into the PRES+ representation. The second technique involves a simulation based approach into which formal methods are injected to boost verification efficiency.
Provided that each individual component is verified and is guaranteed to function correctly, the components are interconnected to form a complete system. What remains to be verified is the interface logic, also called glue logic, aronments as well as the underlying theoretical framework and a step-by-step roadmap on how to apply these algorithms.
Experimental results have proven the efficiency of the proposed techniques and demonstrated that it is feasible to apply them on real-life examples.
