get_packet()

This blocking procedure gets a slave packet that is uniquely identified by the transaction_id
argument previously created by the

create_slave_transaction()

procedure.

It calls the

get_transfer()

procedure for each transfer of the packet, with the number of transfers

defined by the transaction record burst_length field.

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 packet of the tr_id transaction.
get_packet(tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
