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));

Prototype

procedure get_packet

(

transaction_id : in integer;
