Verification of AUTOSAR software architectures with timed automata

Abstract

Today, automotive software is getting increasingly complex while at the same time development cycles are shortened due to time and cost constraints. For the validation of electronic control unit software, this results in a major challenge. Especially for safety critical software, like automotive software, high quality must be guaranteed. Formal verification of automotive software architecture models enables early verification of safety constraints, before the complete system is assembled and ready for simulation. One option for formal verification of safety critical software is modeling and verification using timed automata. In this paper, we present a method for the verification of AUTOSAR software models by transforming the software architecture as well as the corresponding AUTOSAR timing constraints into timed automata.
