Modelling MajorCAN with UPPAAL
Matías Bonet, Gabriel Donaire, Julián Proenza · 2007
The controller area network (CAN) protocol produces data inconsistencies in some scenarios. A previous work proposed a new protocol called MajorCAN which is a small modification to CAN. MajorCAN does not present the reported error scenarios thus ensuring data consistency. Although MajorCAN has been thoroughly simulated, no formal verification has been performed so far. In this paper we describe how we have modelled MajorCAN using a network of timed automata in Uppaal. This is the first step of its formal verification by means of model checking.
