core-rg / fico4omnet

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.

FiCo4OMNeT

FiCo4OMNeT is an open source simulation model for the event-based simulation of fieldbus technologies in the OMNEST/OMNeT++ simulation system. It enables the simulation of CAN and Flexray technologies.

History

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).

News

• Updated dependency to OMNeT++ 6.0.2

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.

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.

Errors while simulating FlexRay example tests

Hello guys,
I am new to this environment, and I tried to run your example tests for CAN and FlexRay. I am facing errors while running FlexRay example codes. Could you give me a solution? CAN examples are going through.

Also, is there a way to print packets during the simulation? I was unable to install osg-earth, I guess that's why the sequence chart is not opening for me. Any tips would be really helpful.
Error message :

CAN FD implementation

Hi Team,

Any plans for implementing CANFD?

Any documentation available to implement?

Trace files

Hello,

Is it possible to read/generate CAN traffic from trace files?

Thanks,

Error message- Simulating Can and flexray Examples

Difference between rxDFLatency and rxDFPayloadLatency

Hi,

I did not really get the difference between rxDFLatency and rxDFPayloadLatency in CanTrafficSinkApp stats, and which one should I rely on if I want to get the end-to-end latency of CAN message?

Thanks,

In CanDataFrame Message where are we setting the Payload value information

packet CanDataFrame{
string displayString;
unsigned int canID; // ID of the message
bool rtr; // true if remote-frame
double period; // Periodicy of the message
}

The above is the CanDataFrame ,on which field do i need to set the Payload information.

In initialFrameCreation("data", dataFrameIDsTokenizer, dataFramesPeriodicityTokenizer,
dataLengthDataFramesTokenizer, initialDataFrameOffsetTokenizer);

we are setting Payload_packet with the size but where are we setting the Payload value?
cPacket *payload_packet = new cPacket;
payload_packet->setTimestamp();
payload_packet->setByteLength(dataFieldLength);
can_msg->encapsulate(payload_packet);

I am refering to 8 bits Data or dataframe
DATA– Used to store up to 64 data bits of application data to be transmitted.
