“…We recall that acceleration has also been applied proficiently in the analysis of real time systems (e.g., [8,25]), to compactly represent the iterated execution of cyclic actions (e.g., polling-based systems) and address fragmentation problems.…”

Abstraction (in its various forms) is a powerful established technique in modelchecking; still, when unbounded data-structures are concerned, it cannot always cope with divergence phenomena in a satisfactory way. Acceleration is an approach which is widely used to avoid divergence, but it has been applied mostly to integer programs. This paper addresses the problem of accelerating transition relations for unbounded arrays with the ultimate goal of avoiding divergence during reachability analysis of abstract programs. For this, we first design a format to compute accelerations in this domain; then we show how to adapt the so-called 'monotonic abstraction' technique to efficiently handle complex formulae with nested quantifiers generated by the acceleration preprocessing. Notably, our technique can be easily plugged-in into abstraction/refinement loops, and strongly contributes to avoid divergence: experiments conducted with the MCMT model checker attest the effectiveness of our approach on programs with unbounded arrays, where acceleration and abstraction/refinement technologies fail if applied alone.

“…The first version of Uppaal was released in 1995 [34]. In the same spirit as any other professional model checker such as SPIN, Uppaal proposes efficient data structures [36], a distributed version of Uppaal [3,10], guided and minimal cost reachability [8,9,33], work on UML Statecharts [23], acceleration techniques [25], and new data structures and memory reductions [7,11].…”

Abstract. In this paper, we introduce a parametric semantics for timed controllers called the Almost ASAP semantics. This semantics is a relaxation of the usual ASAP semantics (also called the maximal progress semantics) which is a mathematical idealization that can not be implemented by any physical device no matter how fast it is. On the contrary, any correct Almost ASAP controller can be implemented by a program on a hardware if this hardware is fast enough. We study the properties of this semantics, show how it can be analyzed using the tool HyTech, and illustrate its practical use on examples.
