Hi Team,

i have query regarding UVM call back on sequence. what is sequence does not attach with any sequencer. How I am going to attach callback to it.

for attaching a task with call back we need to place following hook

`uvm_do_obj_callbacks(mem_sequencer,mem_callback,p_sequencer,update_pkt(req));

what if no sequencer is attached

We do not recommend the use of callbacks in most cases. Proper use of OOP practices by extending your sequence and overriding the methods you want is much more efficient.
