get_data_words()
This nonblocking procedure gets a data_words field array element for a transaction that is
uniquely identified by the transaction_id field previously created by either the
create_write_transaction() or 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));
-- Get the data_words field for the first data phase (beat)
-- of the tr_id transaction.
get_data_words(data, 0, tr_id, bfm_index, axi_tr_if_0(bfm_index));
