set_data_words()

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

create_write_transaction()

procedure.

Example

-- Create a write transaction with start address of 1.
-- Creation returns tr_id to identify the transaction.
create_write_transaction(1, tr_id, bfm_index, axi4_tr_if_0(bfm_index));

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