In this work we propose the introduction of array iterators to the synchronous dataflow language Lustre as a mean to alleviate this complexity. We propose these new operators to provide Lustre programmers with a new mean for designing regular reactive systems. We study a compilation scheme that allows us to generate efficient loop imperative code from these iterators. This language aspect of our work has been fruitful since the iterators are being introduced in the industrial version of Lustre. Finally we propose to take these regular structures into account during the validation process. This approach has already shown its applicability on different real-life case studies. The work we relate here is thus complete in the sense that our propositions at the language level are taken into account both at the compilation and the validation levels.

INTRODUCTION . Reactive systems and the synchronous approach Reactive systems as defined in 1 are characterized by the interaction with their environment being the prominent aspect of their behavior. Software embedded in aircraft nuclear plants and similar physical environments is a typical example. Moreover they .
