CAN FD module supports HiL testing, rapid prototyping

Hardware and software solutions provider dSpace has unleashed its 2014-B test software that supports CAN FD, the automotive data bus with extended bandwidth, as well as a plug-on module for its hardware-in-the-loop (HiL) test and rapid prototyping systems. The company has included an FPGA in the plug-on module that makes the device future proof, added dSpace.

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 four 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 existing 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 hurting the benefits of a classic CAN such as flexibility and affordability.
