set_data()

set_data()

This nonblocking procedure sets a data field array element for a master transaction that is
uniquely identified by the transaction_id field previously created by the

create_master_transaction()

procedure.

The data byte is identified by the optional index argument. If no index is supplied, then the first
data byte is accessed in the array.

Example

-- Create a master transaction containing 3 transfers.
-- Creation returns tr_id to identify the transaction.
create_master_transaction(3, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));

-- Set the data field to 2 for the first byte
-- of the tr_id transaction.
set_data(2, 0, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));

-- Set the data field to 3 for the second byte
-- of the tr_id transaction.
set_data(3, 1, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
