For JESDB
Step-1 First run the simulation with some link0_rbd_m1
register programmed
Step-2 Read the lane0_f_counter_all_lanes_ready status
register
Step-3 Program the link0_rbd_m1 registers with the
'modulo((lane0_f_counter_all_lanes_ready ' + 2), F*K/4) and
run the simulation
Step-4 Now read the '
link0_sysref_cnt_on_release_opportunity' status register
Step-5 Again Program the link0_rbd_m1 registers with the
link0_rbd_m1 from Step-3 as modulo(('link0_rbd_m1 from
Step-3' + link0_sysref_cnt_on_release_opportunity), F*K/4)
and run the simulation
Step-6 Now if you read back the register '
link0_sysref_cnt_on_release_opportunity', it should read back
as 0
For JESDC

Step-2 Read the lane0_f_counter_all_lanes_ready status
register
Step-3 Program the link0_rbd_m1 registers with the
'modulo((lane0_f_counter_all_lanes_ready ' + 2), 64*K) and
run the simulation
Step-4 Now read the '
link0_sysref_cnt_on_release_opportunity' status register
Step-5 Again Program the link0_rbd_m1 registers with the
link0_rbd_m1 from Step-3 as modulo(('link0_rbd_m1 from
Step-3' + link0_sysref_cnt_on_release_opportunity), 64*K) and
run the simulation
Step-6 Now if you read back the register '

as 0
