CoRE Simulation Models for Real-time Networks


FiCo4OMNeT stands for „Fieldbus Communication For OMNeT“. At this point the model consists of two communication technologies – CAN and FlexRay. Both of them are implemented based on the according specification with some adaptions to fit in the simulation environmnet.

Features CAN

It is possible to create networks with traffic consisting of Data-, Remote- and Error-Frames. To get some variation in the transmit and receive times of cyclic messages it is possible to simulate a clock drift.

The arbitration ensures that the frame with the highest priority is transmitted as soon as several nodes try to transmit their messages.

Features FlexRay

Each node can transmit messages in the assigned slots within the static and the dynamic segment. Based on the configuration the frame is transmitted on channel A, channel B or on both. Every member of the network has an own clock. Based on the configuration each clock has an inaccuracy. The implemented synchronisation compensates theses drifts.


FiCo4OMNeT was first introduced as FlexRay simulation model at the 6th International Workshop on OMNeT++ (2013) along with the 6th International ICST Conference on Simulation Tools and Techniques (2013). You can find the publication and slides here.

To merge the simulation models of CAN and FlexRay significant changes were necessary. The result of this merging process is the FieldBus for OMNeT++ Simulation model (FiCo4OMNeT)
