Scope block doesn't show any data inside a reference model block
显示 更早的评论
Hello, I am running one of the reference applications in simulink. Inside that model there are several reference model blocks....what I am trying to do is to place a scope inside one of those blocks to see the resulted signals rather than going back to the visualization block. I tried several solutions like auto scale and limited data options in the scope settings but with no success. I think there might be an option to adjust because the scope works fine for the output signals from the reference block itself but inside the ref model block, it doesn't show anything . I also tried the logging signals option it also woorks fine inside the model reference block

Which reference model are you running? I have an idea what the cause might be, but it would be nice to confirm it before sharing an answer which might be incorrect.

Hey Mohamed Abdullah,
I understand that you are running a reference application in Simulink and want to place a scope inside one of the reference model blocks to view the resulting signals. You have tried options like auto scale and limited data in scope block settings, but it doesn't work within reference model. The logging signals option works fine inside the block.
This might be happening as your model might be running in “accelerated mode” and “Scopes” don’t work well in this mode because Simulink generates a C-MEX S-function for the model for run-time execution, and “Scopes” are not part of that S-function.
To see the output of internal signals in a reference model, you can try the following approaches:
- Using "outport" blocks in the model reference and scoping the relevant signals from the top-level model.
- Using the Simulation Data inspector (either from the top-level model or from the model reference) and logging the desired signals.
For more information about the Scope block, you can refer its documentation : Display signals generated during simulation - Simulink - MathWorks India
Hope this helps!
