Sequence Viewer stays in Idle state

Sequence viewer does not work when I follow the instructions for using the Sequence Viewer Tool. It stays in Idle state even after the model has been run.

I have tried running the example sf_msg_traffic_light and there the Sequence Viewer works (once the model starts running, the state goes from Idle to Running.

Model is R2020b, but this behavior is replicated in R2021a.

Are there some hidden model settings that influence this?

Hey MZ,

There could be several reasons why the Sequence Viewer is not working for your model, even though it works for the example sf_msg_traffic_light. Here are some steps you should go through-

1. Make sure that you have included the correct code in your model to enable the Sequence Viewer which includes importing the necessary modules and defining the correct configuration.
2. Check that you have the necessary dependencies installed. Make sure that these are installed and up-to-date on your system.
3. Verify that the model is actually running. If the model is not running, the Sequence Viewer will remain in the Idle state.
4. Check the log output for any errors or warnings related to the Sequence Viewer. Look for messages related to the viewer in the console output or log files.
