Interrupt Timed Automata with Auxiliary Clocks and Parameters
Interrupt Timed Automata (ITA) are an expressive timed model, introduced to take into account interruptions according to levels. Due to this feature, this formalism is incomparable with Timed Automata. However several decidability results related to reachability and model checking have been obtained. We add auxiliary clocks to ITA, thereby extending its expressive power while preserving decidab...
متن کاملPolynomial Interrupt Timed Automata
Interrupt Timed Automata (ITA) form a subclass of stopwatch automata where reachability and some variants of timed model checking are decidable even in presence of parameters. They are well suited to model and analyze real-time operating systems. Here we extend ITA with polynomial guards and updates, leading to the class of polynomial ITA (PolITA). We prove that reachability is decidable in 2EX...
متن کاملParametric Interrupt Timed Automata
Parametric reasoning is particularly relevant for timed models, but very often leads to undecidability of reachability problems. We propose a parametrised version of Interrupt Timed Automata (an expressive model incomparable to Timed Automata), where polynomials of parameters can occur in guards and updates. We prove that different reachability problems, including robust reachability, are decid...
متن کاملInterrupt Timed Automata
In this work, we introduce the class of Interrupt Timed Automata (ITA), which are well suited to the description of multi-task systems with interruptions in a single processor environment. This model is a subclass of hybrid automata. While reachability is undecidable for hybrid automata we show that in ITA the reachability problem is in 2EXPSPACE and in PSPACE when the number of clocks is fixed...
متن کاملVerification on Interrupt Timed Automata
The class of Interrupt Timed Automata (ITA) has been introduced to model multi-task systems with interruptions in a single processor environment. This is a subclass of hybrid automata in which real valued variables consist of a restricted type of stopwatches (variables with rate 0 or 1) organized along levels. While reachability is undecidable with usual stopwatches, it was proved that this pro...
