Cross coverage for transition bins, with each bin containing more than 1 value in it

Oops. I’m sorry. I’ve been carried away by the abc, xyz examples. Its actually the same coverpoint point, but not the same coverpoint expression. It’s like this.

bit [3:0] abc;

cp_abc1 : coverpoint abc{
bin1 = [1:4];
bin2 = [5:7];
bin3 = [8:10];
bin4 = [11:15];
}

cp_abc2 : coverpoint abc{
bin1 = [1:2];
bin2 = [3:5];
bin3 = [6:9];
bin4 = [10:15];
}

So, it’s all the values of abc divided into 8 categories (8 bins). And I need to collect coverage whenever there is a transition from a value in the range of [1:4] to a value in the range of [1:2] i.e something like [1:4] => [1:2] (this should be taken as 1 bin, instead it gives me 4x2 = 8 bins taking individual values in the range).

So, in this manner I need to get 4x4 16 bins,
like [1:4] => [1:2]
[1:4] => [3:5]
[1:4] => [6:9]
[1:4] => [10:15]

[5:7] => [1:2]
[5:7] => [3:5]
.
.
.
.
[11:15] => [10:15]

Sorry about the confusion. Thanks
