MATLAB: Mux to Bus error message

Question

I'm getting a strange error when trying to run one of our models in simulink: I'm being told 'The block diagram 'Filename' uses bus signals. However, the 'Mux blocks used to create bus signals' diagnostic is not configured to 'error'. To prevent modeling errors:'

Why am I getting an error message for something I've deliberately turned off? Due to the way the model interfaces with our software it has to have a mux creating a bus otherwise it won't work so I can't replace the muxes with buses.

Hi Matthew,

To avoid this error please navigate to

Model Configuration Parameters (Ctrl+E) >> Diagnostics >> Connectivity >> Mux blocks used to create bus signals:

and set the value to "error".

Please note that this diagnostic needs to be set to "error" whenever there is a bus signal in the Simulink model so as to ensure that there will not be any problems with block connections while compiling the model.

Hope this helps!
