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

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, When I am running S-Function for code coverage, I am getting following issue
the start offset must be less than the end offset
Caused by:
A fatal error occurred when accessing the coverage tool: cvi.TopModelCov.modelTerm
Any solution for it?

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:
