Hi,

I am new to simulink and I am trying to check compatibility of a model (file attached) but I get error "call cycles detected"

I dont know how to resolve this or what exactly is the issue kindly provide any information to help me reolve this

Does that use Simulink Designer Verifier product? I do not have that product. Without it, I do not see any kind of Design Verifier option.

@Walter Roberson Thank you for cheking .

Yes it might need to be added , it is part of design , verification and testing models

Hi Amrith,

I was able to reproduce the error on my end. As the error suggests, call cycles are not supported for Simulink Design Verifier.

A potential reason for that is that the chart uses undirected event broadcasts using the function “send”. The documentation recommends preferring directed event broadcasts over undirected event broadcasts to prevent unwanted recursion:

https://www.mathworks.com/help/stateflow/ug/guidelines-for-avoiding-unwanted-recursion-in-a-chart.html#mw_c11c274e-2287-4a35-89d9-d2d1bcb379ab

You may read more about the error and ways to avoid it in this MATLAB Answers post:

For more details on how to detect and fix cyclic behaviour, this documentation might help:

I hope it helps.

Thank you so much.

The error messages in simulink and matlab is often not very useful I hope they improve this
