FMitF: Track II: Hybrid and Dynamical Systems Verification on the CPS-VO

该项目旨在将网络物理系统验证过程部分自动化的最新研究成果转化为更广泛的实践，特别是工业和学生用户。网络物理系统（CPS）是与物理相结合的网络化嵌入式计算系统，如机动车辆、飞机、医疗设备和电网。由于它们经常用于可能发生重大损失的安全关键场景，例如人命或金钱，因此此类系统的工程过程将大量资源用于验证过程，以确保这些系统满足其要求。该方法建立在过去三年举办的混合系统验证竞赛（ARCH-COMP）中最近取得的成功之上，在该竞赛中，几十种混合系统验证工具在几个问题和系统类别中进行了竞争。为了将CPS模型的验证研究成果转化为更广泛的实践，该项目开发了一个基于云的框架，使用NSF的CPS虚拟组织（CPS- vo）与来自混合和动态系统验证社区的最先进的正式验证软件工具进行接口和执行。该项目扩展了CPS-VO的设计工作室和工具集成框架，为这些验证工具提供了一个易于使用的界面。它还可以作为存储工具和基准的可执行版本的存储库，并通过分布式、基于云的执行架构促进ARCH-COMP的可重复性评估。构建该工具的核心技术是混合系统模型源转换和翻译（HyST）软件工具，它在最先进的混合系统验证工具之间执行语义保留转换。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to transition recent research results that automate portions of the verification process of Cyber-Physical Systems into broader practice, particularly with industrial and student users. Cyber-physical systems (CPS) are networked embedded computing systems coupled with physics, such as in motor vehicles, aircraft, medical devices, and the electrical grid. Due to their frequent use in safety-critical scenarios where significant losses may be incurred, such as of human life or monetarily, the engineering process for such systems devotes vast resources to the process of verification to ensure these systems meet their requirements. The approach builds upon recent successes in the hybrid systems verification competition (ARCH-COMP) hosted in the past three years, in which several dozen hybrid systems verification tools have competed across several problem and system categories. To achieve the transition of verification research results for CPS models into broader practice, this project develops a cloud-based framework to interface with and execute state-of-the-art formal verification software tools from the hybrid and dynamical systems verification community using NSF's CPS Virtual Organization (CPS-VO). The project extends the Design Studio and Tool Integration frameworks for the CPS-VO, to provide an easy-to-use interface for these verification tools. It also serves as a repository for housing executable versions of the tools and benchmarks, plus facilitating repeatability evaluations for ARCH-COMP through a distributed, cloud-based execution architecture. The core technology upon which the tool is built is the hybrid systems model source transformation and translation (HyST) software tool, which performs semantics-preserving translation between state-of-the-art hybrid systems verification tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
