In reply to mperyer:
Actually I am trying to understand the environment flow in an existing env which I may reuse later times.
Now the top environment has three block level env and a toplevel virtual sequencer.
I could see that in all the three block envs, user defined sequence is set as default_sequence
From the top env the count of all the three block level sequencer are set as zero.
This must be done to disable block level sequencer?
So that only virtual sequence will run.
Is my understanding correct?
In that case there is a relation between count and default_sequence(weather it is ovm_random_seq or a user defined seq).
