In this thesis, we present a technique and the related tool called HyLink for translating a useful subclass of SLSF diagrams to hybrid automata. In the absence of official semantics, there are two possible interpretations of these diagrams: one is based on the ideal mathematical interpretation obtained from the syntax of the building blocks and the other is based on the simulation traces generated by the simulation engine. These two interpretations lead to two different kinds of hybrid automata---the former gives an automaton with state-dependent transitions and the latter gives a time-triggered automaton. We show that under certain assumptions, the semantics of the latter converge to the former as the simulation step size decreases. We illustrate HyLink's translation scheme, the assumptions, and the convergence result through several case studies.
