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!
