This nonblocking procedure sets the lock field for a transaction that is uniquely identified by the
transaction_id field previously created by either the

create_write_transaction()

create_read_transaction()

procedure.

AXI3 Example

-- Create a read transaction with start address of 1.
-- Creation returns tr_id to identify the transaction.
create_read_transaction(1, tr_id, bfm_index, axi_tr_if_0(bfm_index));

-- Set the lock field to exclusive for the tr_id transaction.
set_lock(AXI_EXCLUSIVE, tr_id, bfm_index, axi_tr_if_0(bfm_index))
