Covergroup bins question

I want to have a bin like this.

bins mid_ranges = {[A:B], [C:D], [E:F]…}

I want it to create 1 bin for each of the groupings [A:B] etc.

Is it possible?

In reply to sharatk:
You need to move up a level and convert your bins to coverpoints
One way:

b1 : coverpoint myvar { bins bin = ([A:B]);}
b2 : coverpoint myvar { bins bin = ([C:D]);}
b3 : coverpoint myvar { bins bin = ([E:F]);}

or another

b1 : coverpoint myver inside {[A:B]} { bins bin = (1);}
b2 : coverpoint myvar inside {[C:D]} { bins bin = (1);}
b3 : coverpoint myvar inside {[E:F]} { bins bin = (1);}

Got it. I was trying to accomplish it in 1 line. Otherwise I had this in my mind.

bins mid_ranges_1 = {[A:B]}
bins mid_ranges_2 = {[C:D]}
So on…
Well that way I can still do in 1 coverpoint, but have to write whole bunch of addresses in multiple lines. From your reply it seems that it isnt possible.

Thanks for answering. Appreciate your help.

That way would also work. Some people just try to accomplish too much with the bin construct. But any way will take multiple lines.
