[sv-ec] Query regarding illegal_bins with default

Hi

I have a query regarding illegal bins  defined with 'default'  keyword.

Consider the following example:

reg[2:0] a;
coverpoint a {
 bins b1[] = {5};
 ignore_bins ig [] = {6};
 illegal_bins il[] = default;
}

Now suppose during sampling, values occurred for 'a' is '6' then  whether
this value will be ignored or it will be treated as illegal value and 
error will be generated.

Basically i wanted to confirm that while computing 'default' values for 
illegal_bins
1) should we exclude values  only in normal bins
2) should we exclude values in normal bins as well as in ignore /illegal 
bins with explicit defined values.


Thanks
