Hi Lina Lin,
Without going into set syntax, I assume, when using set, one can specify the actual instance that gets the configuration value or any instance with a given name.
For example, if I have 2 instances as below:
top.module_a.instance_a
top.module_b.instance_a
Then I can specify set only for top.module_a.instance_a or
I can specify set for instance_a in which case both top.module_a.instance_a and top.module_b.instance_a would get the value.
Is my understanding correct?
