get_id()

This nonblocking procedure gets the data stream identifier id field for a slave transaction that is
uniquely identified by the transaction_id field and previously created by the

create_slave_transaction()

procedure.

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 id field of the tr_id transaction.
get_id(id, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
