Tool Chain to Support Automated Formal Verification of Avionics Simulink Designs
Conference paper
Abstract
Embedded systems have become an inevitable part of control systems in many industrial domains including avionics. The nature of this domain traditionally requires the highest possible degree of system availability and integrity. While embedded systems have become extremely complex and they have been continuously replacing legacy mechanical components, the amount of defects of hardware and software has to be kept to absolute minimum to avoid casualties and material damages. Despite the above-mentioned facts, significant improvements are still required in the validation and verification processes accompanying embedded systems development. In this paper we report on integration of a parallel, explicit-state LTL model checker (DiVinE) and a tool for requirements-based verification of aerospace system components (HiLiTE, a tool implemented and used by Honeywell). HiLiTE and the proposed partial toolchain use MATLAB Simulink/Stateflow as the primary design language. The work has been conducted within the Artemis project industrial Framework for Embedded Systems Tools (iFEST).
