Grab and lock in sequence and sequencer

atalur · December 30, 2018, 3:39am

I have noticed that lock and grab are implemented under uvm_sequence_base and uvm_sequencer_base within the UVM BCL.

I have always seen a lock or a grab on a sequencer called from a sequence (virtual or standalone) like so -

this.lock(<sequencer>) - from a virtual sequence

p_sequencer.lock(this) - from a running standalone sequence

Can somebody explain the calls to the lock/grab under the sequencer? How is it different?
