I was doing Simulik Onramp, at Training - Tasks 10.1 I couldn't proceed to Task 2 due to this "Error evaluating 'StopFcn' callback of block_diagram 'SimulinkOnramp'." block diagram error. I have followed the solution but still encountering same error. Can someone help to resolve this error

Hi Sai,

When encountering the error "Error evaluating 'StopFcn' callback of block_diagram 'SimulinkOnramp'" during the Simulink Onramp training, it indicates there might be an issue with the Simulink model or the environment setup.

Here are few steps you can take to resolve this issue:

Reset the model: You can click on the "Reset" button next to the "Submit" button to reset the model and then try to add the Integrator block from the Simulink > Continuous library and connect it to the Ramp and Signal Assessment blocks.
Restart Simulink Onramp: Occasionally, issues can arise from the session state. Restarting the Simulink Onramp training might help reset the state and resolve the error.

I hope it helps!
