Observer Port error: Observer Port is mapped to an invalid block, because this block is inside a function-call subsystem.

13 views (last 30 days)
Hello,
I'm testing the Simulink model at the component level by using Simulink test. I need to verify some internal signals. In this way I tried to use the Observer Reference Block and Observer Ports. I followed the steps from the link: Access Model Data Wirelessly by Using Observers - MATLAB & Simulink (mathworks.com).
I get the following error:
Observer Port is mapped to an invalid block, because this block is inside a function-call subsystem.
I was wondering if this is a tool limitation or is it somethig that I am doing wrong?
I appreciate a lot your support! Thank you very much!

Hi, thanks for your response!
Could you please give me a hint without checking the model? I am not allowed to share the models.

Hi Diana! As per the following documentation link (https://www.mathworks.com/help/sltest/ug/access-model-data-wirelessly-by-using-observers.html), the "Observer Port" block can observe the following signals:
  • Continuous-time and Discrete-time signals
  • Zero-order hold signals
  • Scalar signals
  • Wide signals
  • Nonvirtual bus signals
  • Messages
  • Conditional subsystem signals
  • Stateflow® local data parameters, except locals, parameters, signals, and other data defined in a Simulink subsystem inside a Stateflow state.
  • Stateflow state self activity, except if that activity is in a Simulink subsystem inside a Stateflow state.
So, it appears that a function-call subsystem is probably not supported yet. But to achieve similar results, you can propagate and log the signal outside the function-call subsystem using a "Data store" block.
You can refer to the following documentation link to learn more: https://www.mathworks.com/help/simulink/ug/data-store-basics.html.
Hope this helps!
