Increased bandwidth for HiL simulators

Novacarts HiL simulators from Micronova now come with CAN FD. The enhancement permits automotive manufacturers to use Novacarts systems to test communication between control units over CAN FD.

CAN FD enables significantly higher data transmission rates than Classical CAN and is therefore suitable for more complex control units requiring greater bandwidth. The enhanced CAN protocol is now integrated in all new Novacarts HiL (Hardware-in-the-loop) simulators. It is also possible to upgrade existing systems. While integrating CAN FD, Micro Nova also upgraded the vehicle bus nodes used in its test systems as well as its test operation software in order to allow a link between gateways and error functions. Since the new HiL systems use the same tool chain as all Novacarts systems, experienced users can continue to work as usual.

“Classic CAN buses are increasingly reaching their limits as a result of the constant growth in the volume of communication in vehicles,” explained Martin Bayer, Business Unit Head of Testing Solutions at Micronova. “CAN FD offers car makers and automotive suppliers a powerful and inexpensive solution for building on the well-proven and familiar CAN standard and at the same time for creating additional bandwidth in their bus systems.”

The CAN FD protocol allows more data to be transferred than the Classical CAN standard. To achieve this, the payload was increased from eight to 64 bytes and a faster data transmission rate introduced.
