Unable to get cross coverage results written for reg model

Hi all,

in the cross coverage written for the below , im unable to get the results , please can anyone look into the issue
im calling the reg_blk.sample() method in the end of run_phase in test method.


covergroup c1;
   option.per_instance = 1;
a : coverpoint regA.value[2:0];
b : coverpoint regB.value[2:0];
c : coverpoint regC.value[4:0];

axbxc : cross a,b,c
{
   bins a_0_b_1_c_0 = binsof(a) intersect{'d0} && binsof(b) intersect{'d1} && binsof(c) intersect{'d0} ;
   bins a_0_b_1_c_1 = binsof(a) intersect{'d0} && binsof(b) intersect{'d1} && binsof(c) intersect{'d1} ;
   bins a_0_b_2_c_0 = binsof(a) intersect{'d0} && binsof(b) intersect{'d2} && binsof(c) intersect{'d0} ;
   bins a_0_b_2_c_1 = binsof(a) intersect{'d0} && binsof(b) intersect{'d2} && binsof(c) intersect{'d1} ;
   bins a_0_b_2_c_2 = binsof(a) intersect{'d0} && binsof(b) intersect{'d2} && binsof(c) intersect{'d2} ;
   bins a_0_b_2_c_3 = binsof(a) intersect{'d0} && binsof(b) intersect{'d2} && binsof(c) intersect{'d3} ;

I’ll repeat to you:

It always helps to explain what your expectations are versus what you see happening, especially when you have provided so little code.

Sorry …

there needs to be cover the reg_model and in that individual coverpoints build are covering up
but Cross coverage bins are not getting covered …

What are the values of regA, regB, regC when you do each sample?
