Coding for covergroup with coverpoint and cross

In reply to rgarcia07:

I want these coverage combinations
enable mode
1 00000001
1 00000010
1 00000100
1 00001000
1 00010000
1 00100000
1 01000000
1 10000000

but I’m not sure how the coverage tool is calculating the coverage.

How to refine the coverage to only check the above combinations ?
