CAN Message Reception Behavior in Simulink

Observe the message processing behaviors of the CAN Receive and CAN Unpack blocks in multiple modeling scenarios. This example demonstrates two cases, with and without using the function trigger f() port of the CAN Receive block. The outputs of the model indicate the number of CAN messages unpacked for downstream processing in each case. The example uses MathWorks virtual CAN channels to send CAN messages from MATLAB to the Simulink model. These modeling practices and behavior also apply to the CAN FD protocol using the Vehicle Network Toolbox CAN FD blocks.

Programmatically Build Simulink Models for CAN Communication

Programmatically construct a Simulink® model to introduce CAN or CAN FD communication using a CAN DBC file. With the add_block (Simulink) and set_param (Simulink) functions of Simulink, one can add and fully configure Vehicle Network Toolbox™ blocks to add network communication to a basic algorithm. The DBC file contains the CAN messages and signal details. The primary focus is to programmatically configure CAN and CAN FD Pack and Unpack block parameters. This can significantly increase model construction efficiency.
