Abstract
The formal verification of software systems often requires the integration of multiple tools and techniques. To ensure the accuracy of any verification done and to ensure the applicability of formal methods to industrial use cases, traceability must be maintained throughout the process so that it is clear what the requirements for the system are and how they are fulfilled. We propose a three-phase methodology for formal verification with the aim of ensuring traceability, built around the Formal Requirements Elicitation Tool (FRET). Our current case study applies this methodology to the use of FRET, Simulink and Event-B for the verification of the software controller for a civilian aircraft engine.
This research was funded by the European Union’s Horizon 2020 research and innovation programme under the VALU3S project (grant No 876852), and by Enterprise Ireland (grant No IR20200054). The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
