Model Checking Group

Details: Category: Uncategorised; Last Updated on Monday, 26 November 2012 10:03

Our main research activity focuses on Model Checking based algorithms and tools for automatic analysis and synthesis of mission or safety critical reactive systems.

A reactive system is a nonterminating system continuously exchanging information (input/output) with its environment in order to reach given goals. Examples of reactive systems are: digital hardware, control systems, operating systems, communication protocols, business processes, Decision Support Systems (DSS), Sense and Respond (SaR) systems in general.

Typically a system is considered mission critical when its failure may entail a loss of money whereas it is considered safety critical when its failure may entail loss of human lives.

Examples of mission critical systems are: space satellites, Decision Support Systems, ERP (Enterprise Resource Planning) systems. Examples of safety critical systems are: railway interlocking systems, airplanes.

SyLVer

Details: Category: Software; Last Updated on Wednesday, 01 February 2017 12:15

SyLVer [MicPro16,PDP15,PDP14,CAV13,SpaceOps12,DASIA11] is a software allowing System Level Formal Verification (SLFV) of Cyber Physical Systems (CPSs). SyLVer implements an assume-guarantee approach to the problem of SLFV.

The goal of SLFV is to show system correctness notwithstanding uncontrollable events (disturbances), as for example faults, variation in system parameters, external inputs, etc. This may be achieved with an exhaustive Hardware In the Loop Simulation (HILS) based approach, by considering all relevant scenarios in the System Under Verification (SUV) operational environment.

SyLVer is a stand-alone software completely running on the user premises. Furtherly, it is possible to exploit MCLab Group cloud infrastructure potential for SyLVer, by using our derived and dedicated Web-based software SyLVer as a Service (SyLVaaS). With SyLVaaS, the generation of relevant scenarios is executed in MCLab cloud infrastructure but HILS activity still takes place on the user premises (as for SyLVer), thus allowing full Intellectual Property protection on the SUV model and the user verification flow.

Introduction to QKS

Details: Category: Software; Last Updated on Friday, 31 March 2017 09:54

QKS [TOSEM14] is a tool for automatic synthesis of correct-by-construction control software (as C code) for Discrete Time Linear Hybrid Systems. More in detail, QKS outputs a control software for software-based control systems like the following:

where we highlight the fact that:

measures from plant sensors go through an Analog-to-Digital (AD) conversion (quantization) before being processed;
the control software is typically executed by a microcontroller.
