Why do I get Coverage error .

Why this error, Not able to highlight because model changed error during Coverage analysis

With every model I used.

Hi Shivam,

I assume you are collecting "aggregate" (or "cumulative") coverage across multiple simulations. Is that correct?

If so, did you change the model between simulations? The coverage highlighting will only work when displaying coverage for simulations of the same model version.

Thanks.

Hi Pat,

So when model have been changed, I need to create new harness then enable to doing coverage test?

Hi @Ian

The answer below can be helpful to you too.

Hi Shivam,

The problem you are encountering may be due to changes made in the model between multiple simulation runs. The Coverage Report can be aggregated over multiple coverage runs, but the model needs to remain unchanged for this to work correctly.

As of the latest version, R2024a, you can make changes between coverage runs, but the coverage results are generated and highlighted only for the runs with an unchanged model. If you try to include runs with a changed model, an error will be generated.

R2024a introduces new features to generate coverage reports over multiple simulations using Design Studies. Refer to the following resource to understand how to use this new feature: [Collect Coverage for Multiple Simulations](https://www.mathworks.com/help/slcoverage/ug/collect-coverage-for-multiple-simulations.html).

I hope you find the above explanation and suggestions useful!
