get_data()

April 2014

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 create_monitor_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 monitor transaction.

-- Creation returns tr_id to identify the transaction.

create_monitor_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));
