get_data()
This nonblocking procedure gets a data field array element for a transaction that is uniquely
identified by the transaction_id field previously created by the
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 slave transaction.
-- Creation returns tr_id to identify the transaction.
create_slave_transaction(tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the data field for the first byte of the tr_id transaction.
get_data(data, 0, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
-- Get the data field for the second byte of the tr_id transaction.
get_data(data, 1, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
