Stateflow Stepping Problem - fatal error when accessing cvi.TopMod​elCov.mode​lPause

Hello everyone, I'm trying to simulate a stateflow model step-by-step but i can't. If i simulate it normally, clicking the green-play button, i can do it...but stepping the model it seems to be impossible. I'm not allowed to pause the model in a given moment too.

I got the following errors:

- Attempt to reference field of non-structure array. Caused by: A fatal error occurred when accessing the coverage tool: cvi.TopModelCov.modelPause - An error occurred while stepping through the simulation and the simulation was terminated

Is there anyone who can help me? Thanks in advance and happy new year! Marco

I am getting this issue as well when I attempt to simulate a model and it is preventing me from running a simulations script.

Hello,

Try this one,

1) Goto home window of matlab

2) Set path

3) Set folder path of your model.

4) Save.

5) Again do the basic settings for coverage

6) Simulate Your Model.

Hello Team,

I am also facing the same issue during the model simulation i am getting the following error:

metricdata.isa : class -- readonly

Error in parameter number 3.

metricdata.isa : class -- readonly

Error in parameter number 3.

An error occurred while running the simulation and the simulation was terminated

Caused by:
