Can't understand how covergroup sample works

In reply to alexd555:
What you get depends what you are stimulating. The covergroup is only evaluating the data you are generating.

I don’t understand your question.
Can you give me an example ?

In reply to alexd555:

Another question. Can you send me your code to my email:
christoph@christoph-suehnel.de

Yes but why is it another question ?

In reply to alexd555:

This is another kind of question. It is not a technical one.
