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 (down)
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 (down)
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 (down)
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 (down)
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.
