System Composer: how to create input/output port in system architecture model?

Hi, I am new to system composer 2022a and trying to build system architecture using system composer. I have one input output physical interface(e.g CAN). How can i create input/output port for CAN? i tried creating two ports 1 input and 1 output using the same name but system composer doesn't accept same name for two ports. So is there a possibility to create one input/output port in system composer?

Hi Gadi,

The recommended method in System Composer would be to create in/out pairs of ports by name so you would have, for example: CAN_Ch1_In and CAN_Ch1_Out since bidirectional ports are not supported explicitely. You can then also apply the same interface to the ports for parity.

Note, if you are modeling message data across the bus, you should use the input/output pairs. If you are modeling the actual hardware behavior of the CAN bus, you can use physical ports instead, which are not directional.

Here is more information on physical ports:
