It took me a while to understand "match clause", but I still can't think of any practical case that need it.
Could someone help to provide some examples that show it's power? Thanks.
The optional matches clause specifies the selection policy. The integer_covergroup_expression shall evaluate to a positive integer or $, representing the minimum number of satisfying value tuples required toselect the candidate bin tuple.
bins apple = X with (a+b < 257) matches 127;
