Hello Programmers,

I want to do PIL simulation in my MATLAB project folder. I can generate PIL block from Simulink and simulate outside of the project folder without any problem. When I want to Simulate inside the Project folder, I can not connect the Arduino Hardware.

I recieve this error;

The file containing block diagram 'Arduino_Funcv1' is shadowed by a file of the same name higher on the MATLAB path. This can cause unexpected behavior. For more information see "Avoiding Problems with Shadowed Files" in the Simulink documentation. The file containing the block diagram is: C:\Users\azizogla\Documents\NXBRAKE2026_SVN\trunk\Simulation\nXBRAKE_01\S-Models\VirtualTest\PILv1\Arduino_Funcv1.slx. The file higher on the MATLAB path is: C:\Users\azizogla\Documents\NXBRAKE2026_SVN\trunk\Simulation\nXBRAKE_01\S-Models\VirtualTest\Arduino_Funcv1.slx

Failed to connect to Arduino board. Verify connection and the host COM port number entered in 'Configuration Parameters > Target hardware resources > Host-board connection' and try again. To find out the COM port number in Windows, open Device Manager and open your board in the COM ports group.

Thank you for your helps.
