Hi Nikolai,
There is a simpler form of DistValSlv that returns values in the range of its argument, which is 0 to 15 if the argument is a literal or aggregate:
A <= RndA.DistSlv((5, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 5), A'length) ;
If you prefer, you can also use named association:
A <= RndA.DistSlv((0=>5, 1=>1, 2=>1, 3=>1, 4=>1, 5=>1, 6=>1,
7=>1, 8=>1, 9=>1, 10=>1, 11=>1, 12=>1,
13=>1, 14=>1, 15=>5), A'length) ;
With named association, you can also do the following:
A <= RndA.DistSlv((0=>5, 1 to 14 =>1, 15=>5), A'length) ;
You can also do this with a coverage model:
shared variable ACov : CovPType ;
. . .
process
begin
ACov.AddBins(5, GenBin(0)) ;
ACov.AddBins(1, GenBin(1,14)) ; ACov.AddBins(5, GenBin(15)) ;
. . .
A <= ACov.RandCovPoint ;
ACov.ICoverLast ;
