[sv-ec] Coverpoint bins & functional coverage

Hi, All -

A question for all you smart coverage experts using SystemVerilog coverage 
capabilities.

·       Coverpoint bins

Can I assume that the coverpoint bins are integers and that I can do random 
functional stimulus generation based on the comparisons to count values in 
the coverpoint bins? (Keep generating more random stimulus until I see a 
coverpoint bin == 2?)

I know that coverpoints and covergroups are used by vendor tools to report 
functional coverage information, but since the bins are already keeping 
track of how many times a coverpoint has been seen, it seems like I should 
be able to loop until I see certain coverpoints incremented.

If I can do this, what will the hierarchical name be for the coverpoints? 
(covergourp_instance_name.bin_name??)

Am I missing something fundamental in these questions?

Regards -  Cliff
