set_data_words()

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

create_slave_transaction()

procedure.

Example

-- Create a slave transaction. Creation returns tr_id to identify
-- the transaction.
create_slave_transaction(tr_id, bfm_index, axi4_tr_if_0(bfm_index));

-- Set the data_words field to 2 for the read data phase (beat)
-- for the tr_id transaction.
set_data_words(2, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
