Supported Communication Standards

With its products, dSPACE supports the most common modern communication standards.


The Fieldbus Exchange Format (FIBEX) is specified by ASAM. FlexRay networks are, in most cases, described by FIBEX files. The files have an XML format and contain information about the complete vehicle network. In detail, they describe the network topology, data frames, signals and their coding and scheduling, as well as dedicated signal parameters.


FlexRay is a standard (ISO 17458)  for in-vehicle, time-triggered communication systems. dSPACE’s FlexRay products provide comprehensive FlexRay support, ranging from hardware, such as prototyping systems and I/O boards with FlexRay interfaces, to software for the real-time simulation of models in FlexRay networks.


Communication database for CAN is one file format for describing the CAN communication between distributed ECUs. The file defines the properties of a CAN network, including its signals, the connected ECUs and the CAN messages. The format is widely used but limited to CAN networks. 

CAN in Automation

The CAN in Automation (CiA) international users’ and manufacturers’ group was founded in 1992 by multiple companies. Its aim is to provide an unbiased platform for future developments of the CAN protocol and to promote the image of CAN.


The LIN description file (LDF) specifies all the signals, data packages and scheduling tables of a LIN bus. The description includes the properties of the master and one or more slave controllers. As can be derived from its name, the file format is limited to LIN buses. 


AUTOSAR XML (ARXML) files describe systems according to AUTOSAR. AUTOSAR (AUTomotive Open System ARchitecture) is an industry partnership that aims to develop and establish an open standard for automotive electrics/electronics (E/E) architectures. A system is a combination of a hardware topology, a software architecture, a network communication, and information on the mappings between these elements. AUTOSAR system description files are instances of the AUTOSAR System Template. Within the file, different bus protocols, including the gateways between these protocols, can be described.


The Ethernet technology allows multiple in-vehicle systems (such as infotainment, automated driver assistance and onboard diagnostics) to simultaneously access information via a single unshielded twisted pair cable. 

OPEN Alliance

dSPACE joined the OPEN Alliance in 2012. The OPEN Alliance was established to encourage the widespread adoption of Ethernet-based, single pair unshielded cable networks as the standard in automotive applications. The OPEN Alliance Special Interest Group (SIG) addresses industry requirements for improving in-vehicle safety, comfort, and infotainment, while significantly reducing network complexity and cabling costs.

SAE J1939

The SAE J1939 vehicle bus standard is based on CAN and used for communication and diagnostics among vehicle components. Application areas cover commercial and off-road vehicles, as well as charging station communication. dSPACE supports the configuration of J1939 bus and network communication throughout its bus tool chain.
