get_user_data()
This nonblocking procedure gets a user_data field array element for a monitor transaction that
is uniquely identified by the transaction_id field previously created by the
create_monitor_transaction() procedure.
The user_data array element is identified by the optional index argument. If no index is
supplied, then the first user_data is accessed in the array.
Example
-- Create a monitor transaction.
-- Creation returns tr_id to identify the transaction.
create_monitor_transaction(3, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the user_data field for the first transfer
-- of the tr_id transaction.
get_user_data(user_data, 0, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the user_data field for the second transfer
-- of the tr_id transaction.
get_user_data(user_data, 1, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
