How can I create or edit a CAN database DBC file and its defined CAN messages and signals?

Does MATLAB provide functionality to

• create a new CAN database DBC file, or
• edit and existing DBC file to add new messages or edit the message and signals definitions?

Vehicle Network Toolbox provides functionality related to CAN database DBC files, such as

• canDatabase, messageInfo, signalInfo to access a *.dbc file (CAN message and signals definitions)
• canMessage, attachDatabase to create and decode message signals based on the definitions in a CAN database DBC file.

It is not currently possible to create or edit a CAN database DBC file with MATLAB.

This can be done with a free 3rd party tool, Vector CANdb++ editor:

Vector CANdb++ editor is installed with the demo version of CANalyzer / CANoe, which can be downloaded from the Vector website:
