Module extends HiL testing and rapid prototyping to CAN FD

January 08, 2015 // By Christoph Hammerschmidt
Along with a new plug-on module for its Hardware-in-the-loop test and rapid prototyping systems, dSpace's test software release 2014-B now supports CAN FD, the automotive data bus with extended bandwidth. An FPGA in the plug-on module enables this device to shoulder future requirements.

The DS4342 CAN FD Interface Module can be integrated into dSPACE RCP systems such as MicroAutoBox and the company's modular hardware for HIL systems. The module features two CAN FD channels that can also be used for communication across the standard version of the CAN bus.

For large numbers of CAN FD channels, up to 4 DS4342 modules can be integrated on a DS4505 carrier board, which is also used for FlexRay communication. It is possible to combine FlexRay and CAN FD interface modules on the same carrier board. This enables users to add CAN or CAN FD to existing systems, thereby protecting their investment.

Similar to current CAN applications, CAN FD communication is configured via the RTI CAN MultiMessage Blockset with its graphical user interface. Familiarity with this configuration software will enable developers to quickly add CAN-FD-specific information to their application.

The CAN FD bus standard offers higher bandwidth than the established CAN protocol. The higher payload data packet size of 64 bytes also increases the bus system's efficiency without scarifying the benefits of a classic CAN such as flexibility and affordability.
