Re: [sv-ec] Query on get_coverage()

Hi Swapnajit,

As stated in the text quoted get_coverage() is a static method.

In the case when it is called on covergroup instance i.e
cgi.get_coverage();

Applying the OOPS concepts it should return the cumulative coverage of the
Type of covergroup Instance on which it is invoked.

Thanks
Saurabh
