On the Formal Verification of the FlexRay Communication Protocol

We present ongoing work on the formal analysis of the FlexRay communication protocol. Isabelle/HOL, a theorem prover for Higher Order Logic, is chosen as our specification and verification system. Essential properties of the FlexRay protocol are identified, formalized and verified. In particular, we show our formal verification of the FlexRay bus guardian component. Furthermore, some insights for the formal verification of the clock synchronization algorithm are exposed.
