Hi Constantin Razvan Chivu,
I have installed other older version before,and have been updated directly to 2018.R1.Does that have anything to do with it?My Matlab version is 2018b.And the simulation error occurred in the standard Simulink simulation of clicking the RUN button.
I 'll try to uninstall the MDBT and reinstall it to see if I can solve the problem. I 'll get back to you when I have something.
Thank you.
