Creating a custom array of cover bins

Coverage

In reply to rgarcia07:

Sure!

Lets say some DataBus:
localparam WIDTH = 32;
logic [WIDTH-1:0] dataBusTest;

where dataBusTest can be (0x100 → 0xFFFF_FC00). This is limited by some mathematical constraints on the upstream logic.

I want to have the following bins:

  1. min_value = { 0x100 }
  2. max_value = { 0xFFFF_FC00 }
  3. 64 bins equally spaced from 0x100 to 0xFFFF_FC00, where the bin names reflect the numerical range they contain.

#3 is the issue. I cant seem to create bins that contain a range of numerical values without getting syntax errors. My current workaround is this:

bins range_bins [BINS_CNT] = {[MIN_VAL:MAX_VAL]};

but the problem is, lets say for bin[0] i get the name bin[0], with auto binning, i would get the bin name bin[256:67109100].

Is this enough information for you?
