  Title Fluid Petri Nets and hybrid model checking: a comparative case study Type Journal Article
  Year 2003 Publication Int. Journal on: Reliability Engineering & System Safety Abbreviated Journal  
  Volume 81 Issue 3 Pages 239-257  
  Keywords  
  Abstract The modeling and analysis of hybrid systems is a recent and challenging research area which is actually dominated by two main lines: a functional analysis based on the description of the system in terms of discrete state (hybrid) automata (whose goal is to ascertain conformity and reachability properties), and a stochastic analysis (whose aim is to provide performance and dependability measures). This paper investigates a unifying view between formal methods and stochastic methods by proposing an analysis methodology of hybrid systems based on Fluid Petri Nets (FPNs). FPNs can be analyzed directly using appropriate tools. Our paper shows that the same FPN model can be fed to different functional analyzers for model checking. In order to extensively explore the capability of the technique, we have converted the original FPN into languages for discrete as well as hybrid as well as stochastic model checkers. In this way, a first comparison among the modeling power of well known tools can be carried out. Our approach is illustrated by means of a ââ¬â¢real worldââ¬â¢ hybrid system: the temperature control system of a co-generative plant.

  Title Integrating Automatic Verification of Safety Requirements in Railway Interlocking System Design Type Conference Article
  Year 2001 Publication High Assurance Systems Engineering, 2001. Sixth IEEE International Symposium on Abbreviated Journal  
  Volume Issue Pages 209-219  
  Keywords  
  Abstract A railway interlocking system (RIS) is an embedded system (namely a supervisory control system) that ensures the safe, operation of the devices in a railway station. RIS is a safety critical system. We explore the possibility of integrating automatic formal verification methods in a given industry RIS design flow. The main obstructions to be overcome in our work are: selecting a formal verification tool that is efficient enough to solve the verification problems at hand; and devising a cost effective integration strategy for such tool. We were able to devise a successful integration strategy meeting the above constraints without requiring major modification in the pre-existent design flow nor retraining of personnel. We run verification experiments for a RIS designed for the Singapore Subway. The experiments show that the RIS design flow obtained from our integration strategy is able to automatically verify real life RIS designs.

  Title Linearising Discrete Time Hybrid Systems Type Journal Article
  Year 2017 Publication IEEE Transactions on Automatic Control Abbreviated Journal  
  Volume 62 Issue 10 Pages 5357-5364  
  Keywords  
  Abstract Model Based Design approaches for embedded systems aim at generating correct-by-construction control software, guaranteeing that the closed loop system (controller and plant) meets given system level formal specifications. This technical note addresses control synthesis for safety and reachability properties of possibly non-linear discrete time hybrid systems. By means of syntactical transformations that require non-linear terms to be Lipschitz continuous functions, we over-approximate non-linear dynamics with a linear system whose controllers are guaranteed to be controllers of the original system. We evaluate performance of our approach on meaningful control synthesis benchmarks, also comparing it to a state-of-the-art tool.

  Title Hardware Verification, Boolean Logic Programming, Boolean Functional Programming Type Conference Article
  Year 1995 Publication Tenth Annual IEEE Symposium on Logic in Computer Science (LICS) Abbreviated Journal  
  Volume Issue Pages 408-418  
  Keywords  
  Abstract One of the main obstacles to automatic verification of finite state systems (FSSs) is state explosion. In this respect automatic verification of an FSS M using model checking and binary decision diagrams (BDDs) has an intrinsic limitation: no automatic global optimization of the verification task is possible until a BDD representation for M is generated. This is because systems and specifications are defined using different languages. To perform global optimization before generating a BDD representation for M we propose to use the same language to define systems and specifications. We show that first order logic on a Boolean domain yields an efficient functional programming language that can be used to represent, specify and automatically verify FSSs, e.g. on a SUN Sparc Station 2 we were able to automatically verify a 64 bit commercial multiplier.

  Title Regular Systems of Equations in λ-calculus Type Journal Article
  Year 1990 Publication Int. J. Found. Comput. Sci. Abbreviated Journal  
  Volume 1 Issue 3 Pages 325-340  
  Keywords  
  Abstract Many problems arising in equational theories like Lambda-calculus and Combinatory Logic can be expressed by combinatory equations or systems of equations. However, the solvability problem for an arbitrarily given class of systems is in general undecidable. In this paper we shall focus our attention on a decidable class of systems, which will be called regular systems, and we shall analyse some classical problems and well-known properties of Lambda-calculus that can be described and solved by means of regular systems. The significance of such class will be emphasized showing that for slight extensions of it the solvability problem turns out to be undecidable.
