For my first que,
Got an Idea, Thank you.
For my second que,
I already coded what you have mentioned in above comment, However I am quite curious to know why it is not possible to sample/access partial field inside coverpoint (like with different bins)?
I even tried below wildcard bins
bins masksMSB = {['h0000_???? : 'hffff_????]};
I didn’t run and check but is it same what you wanted to convey me in your last statement?
