Does NI VeriStand provide support for CAN FD?


VeriStand 2019 or Later
VeriStand 2019 supports XNET implementation for the Controller Area Network Flexible Data-Rate (CAN FD) protocol. With a XNET implementation, you can now use databases that support CAN FD and CAN FD with Baud Rate Switching I/O modes. This implementation also allows calculating and using custom baud rates for a CAN interface. For more information on CAN FD, see Understanding CAN with Flexible Data-Rate (CAN FD) .

VeriStand 2018 SP1 or Earlier
VeriStand 2018 SP1 or earlier doesn't have full native support for CAN FD. However, since NI-XNET provides support for CAN FD beginning with version 14.0, you can use VeriStand with standard CAN FD baud rates. 

When using CAN FD in VeriStand, the Baud rate control in the system definition represents the FD phase. This implies that the baud rate for the normal phase must be set properly in the database and cannot be overridden by the system definition. We recommend that you set the proper baud rates in the database and do not override any values in the system definition.
