Giving equal weight to all bins across all functional cover groups

Hi ,
Please help me.
I am trying to estimate realistic coverage number .
I am using system verilog based Testbench.
Ist cover group has 100 bins and 2nd cover group has 1lac bins.
I am getting coverage percentage only at cover group average and not at total bins level.

example :
I have ten cover groups.
first group has 2 crosses . ten bins of first cross of first group has not covered.
rest all crosses are covered in first group. even rest all groups covered.
I am interested to know percentage of coverage number considering
total bins covered across all groups/total number of bins across all groups

Is their any option to help me to achieve exact coverage finished…

Regards,
Pavan.

In reply to attaluri:

Look at LRM 19.8 section. It looks to me like you are looking for fst_cg.get_coverage() method.
