Internship | Visualization of Formal Verification Findings
About this position
The Machinaide project is a cooperation of TNO, Cordis SUITE, TU/e, Additive Industries, Lely Industries and KE-works. Machinaide aims at the development of digital twins for small- and medium-sized companies; Machinaide specifically targets digital twins of system control applications. Basis of Machinaide’s digital twins is the Cordis SUITE low-code platform, a platform for specification and code generation for system control. Cordis SUITE is being extended with data collection and visualization functionality developed in Machinaide.
What will be your role?
System control applications involve many interacting functions running in parallel. Because of their complexity, it is a challenge to verify and validate system control application. In Machinaide, work is being done on model-based verification using formal methods. The focus has been on the development of user-friendly ways to (1) specify desired system properties (TNO, TU/e) and (2) verify these system properties using run-time verification (TNO) and model checking (TU/e). Run-time verification uses data of actual system executions to check whether desired properties are violated; model checking does the same for all possible system executions of a model of the system.
What is lacking is a user-friendly way to report findings of property violations. This is the topic of this assignment. Gantt charts can be used to visualize system behavior over time, typically showing system actions and their dependencies, but sometimes also discrete events and continuous signals. An example of a versatile Gantt chart visualization tool is ESI’s TRACE tool (see https://trace.esi.nl/). Gantt charts can show actual execution traces, but also counterexamples found by run-time verification and model checking.
In this assignment, a method is to be developed to augment execution traces with property-specific elements to (1) highlight violations of user-defined properties and (2) provide feedback to the user why the property was violated. The augmented execution trace is to be visualized as a Gantt chart. This execution trace augmentation involves relating the user-defined properties to the elements in the execution trace shown in the Gantt chart and highlighting the events leading to a property violation.
The assignment will (if circumstances allow) be carried out at TNO's Embedded Systems Innovation department at the High Tech Campus in Eindhoven in cooperation with Cordis SUITE and TU/e.
