    Self-driving cars, autonomous robots, modern airplanes, or robotic surgery: we increasingly entrust our lives to computers and therefore should strive for nothing but the highest safety standards – mathematical correctness proof. Proofs for such cyber-physical systems can be constructed with the KeYmaera X prover. As a hybrid systems and hybrid games theorem prover, KeYmaera X analyzes the control program and the physical behavior of the controlled system together. KeYmaera X implements differential dynamic logic (dL), a logic for specifying and verifying properties of hybrid systems with mixed discrete, continuous, and adversarial dynamics. KeYmaera X features a minimal core of just 1700 lines of code that isolates all soundness-critical reasoning. Such a small and simple prover core makes it much easier to trust verification results. Pre-defined and custom tactics built on top of the core drive automated proof search. KeYmaera X comes with a web-based front-end that provides a clean interface for both interactive and automated proving, highlighting the most crucial parts of a verification activity.

    This tool demonstration presents VSCode-PVS, a modern integrated development envi- ronment for the Prototype Verification System (PVS). The new environment integrates the editing and proof management functionalities of PVS in Visual Studio Code, a popular code editor widely used by software developers. VSCode-PVS provides functionalities that developers expect to find in modern verification tools, but are not available in the standard Emacs front-end of PVS, such as auto-completion, point-and-click navigation of definitions, live diagnostics for errors, and literate programming. The main features of VSCode-PVS will be demonstrated through a set of examples based on publicly available specifications developed by NASA.

    SafeCap is a platform for applying static formal verification to railway signalling. In cooperation with Siemens Rail Automation UK we have developed a industrial strength extension for processing and verifying UK standard of control tables. Separately, in cooperation with Systra UK, we have developed an extension for translation of signalling computer software into symbolic transition systems and verification of safety principles via inductive safety invariant. In the demo we shall demonstrate the generic part of the tool with the applications to verification of synthetic data sets and transition systems, further we shall demonstrate the functionality of control tables and signalling data verification. We shall also present and offer to share a number of public domain railway case studies comprising node/edge layout models, control tables and signalling data

    In the context of safety- and security-critical Cyber-Physical Systems (CPSs), checking the sanity of functional requirements is an important, yet challenging task. It is largely recognized that a flaw in the requirements specification can lead to delays, additional expenses and, possibly, the failure of the project. Nonetheless, due to the intrinsic difficulty of dealing with natural language sentences, requirements are often checked manually, an error-prone and time-consuming activity. Given the increasing demand and complexity of CPSs, and the need to reduce time-to-market and costs, practical solutions to enable automated verification of requirements are in order. Formal methods provides a viable solution, but they often requires overburdening formalization and a high degree of expertise. As a trade-off between formalization and usability, a recurrent solution in the literature is the use of Property Specification Patterns (PSPs), English-like structured natural sentences that provides a direct mapping to one or more logics. ReqV is a tool developed in the context of the H2020 EU CERBERO project that leverage on PSPs to tackle the problem stated before. We extended PSPs by considering Boolean as well as atomic numerical assertions of the form x =∗ c, where X is a variable of the system, c ∈ R is a constant real number and the operator =∗∈ {<, <=, =, >=, >} have the usual interpretation. Furthemore, we presented an encoding to reduce the inner consistency of extended PSPs, i.e., logical errors in the specification that prevents any possible system to satisfy all requirements, to the Linear Temporal Logic (LTL) satisfiability problem. We also extended the previous work with a new algorithm to find a minimum set of conflicting requirements in case of inconsistency, and we collected all these functionalities in a Java library called SpecPro4. ReqV exploits these capabilities to provide an easy-to-use interface for the verification of requirements. Its goal is to enable users with no background knowledge of formal methods and logical languages to write requirements in PSP forms and check their consistency. ReqV also aims at minimizing the setup process for the user, and therefore it is developed as a web application that can easily be accessed with a browser.

    Uppaal is a suite of tools for formal verification, model-based testing, performance analysis and synthesis of real-time systems. The suite originates from academic papers and experiments, it has become popular in teaching and found its way into a number of industrial applications, such as communication protocols, embedded systems, consumer electronics and automotive designs. At the core the tools use extended timed automata specification as a model to simulate, validate, verify properties, find optimal solutions, interactively visualize the behavior and diagnostic traces, generate test cases in native programming languages, estimate time and cost of operation, and find and optimize control strategies for steering the system in adverse environments. The demonstration shows the principles behind the tools and some instances of specific applications.
