	Title	Anytime system level verification via parallel random exhaustive hardware in the loop simulation			Type	Journal Article
	Year	2016	Publication	Microprocessors and Microsystems	Abbreviated Journal
	Volume	41	Issue		Pages	12-28
	Keywords	Model Checking of Hybrid Systems; Model checking driven simulation; Hardware in the loop simulation
	Abstract	Abstract System level verification of cyber-physical systems has the goal of verifying that the whole (i.e., software + hardware) system meets the given specifications. Model checkers for hybrid systems cannot handle system level verification of actual systems. Thus, Hardware In the Loop Simulation (HILS) is currently the main workhorse for system level verification. By using model checking driven exhaustive HILS, System Level Formal Verification (SLFV) can be effectively carried out for actual systems. We present a parallel random exhaustive HILS based model checker for hybrid systems that, by simulating all operational scenarios exactly once in a uniform random order, is able to provide, at any time during the verification process, an upper bound to the probability that the System Under Verification exhibits an error in a yet-to-be-simulated scenario (Omission Probability). We show effectiveness of the proposed approach by presenting experimental results on SLFV of the Inverted Pendulum on a Cart and the Fuel Control System examples in the Simulink distribution. To the best of our knowledge, no previously published model checker can exhaustively verify hybrid systems of such a size and provide at any time an upper bound to the Omission Probability.

	Title	Linear Constraints and Guarded Predicates as a Modeling Language for Discrete Time Hybrid Systems			Type	Journal Article
	Year	2013	Publication	International Journal on Advances in Software	Abbreviated Journal	Intern. Journal on Advances in SW
	Volume	vol. 6, nr 1&2	Issue		Pages	155-169
	Keywords	Model-based software design; Linear predicates; Hybrid systems
	Abstract	Model based design is particularly appealing in software based control systems (e.g., embedded software) design, since in such a case system level specifications are much easier to define than the control software behavior itself. In turn, model based design of embedded systems requires modeling both continuous subsystems (typically, the plant) as well as discrete subsystems (the controller). This is typically done using hybrid systems. Mixed Integer Linear Programming (MILP) based abstraction techniques have been successfully applied to automatically synthesize correct-by-construction control software for discrete time linear hybrid systems, where plant dynamics is modeled as a linear predicate over state, input, and next state variables. Unfortunately, MILP solvers require such linear predicates to be conjunctions of linear constraints, which is not a natural way of modeling hybrid systems. In this paper we show that, under the hypothesis that each variable ranges over a bounded interval, any linear predicate built upon conjunction and disjunction of linear constraints can be automatically translated into an equivalent conjunctive predicate. Since variable bounds play a key role in this translation, our algorithm includes a procedure to compute all implicit variable bounds of the given linear predicate. Furthermore, we show that a particular form of linear predicates, namely guarded predicates, are a natural and powerful language to succinctly model discrete time linear hybrid systems dynamics. Finally, we experimentally show the feasibility of our approach on an important and challenging case study taken from the literature, namely the multi-input Buck DC-DC Converter. As an example, the guarded predicate that models (with 57 constraints) a 6-inputs Buck DC-DC Converter is translated in a conjunctive predicate (with 102 linear constraints) in about 40 minutes.
