get_data_words()
This nonblocking procedure gets a data_words field for a transaction that is uniquely identified
by the transaction_id field previously created by either the
procedure.
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, axi4_tr_if_0(bfm_index));
-- Get the data_words field for data phase
-- of the tr_id transaction.
get_data_words(data, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
