execute_transaction()
April 2014
execute_transaction()
This procedure executes a master transaction that is uniquely identified by the transaction_id
argument previously created by the
create_master_transaction() procedure. A transaction can
be blocking (default) or nonblocking, based on the setting of the transaction operation_mode
field.
It calls the execute_transfer() procedure for each transfer within a packet, with the number of
transfers defined by the transaction burst_length field.
Example
-- Create a master transaction containing 3 transfers
-- Creation returns tr_id to identify the transaction.
create_master_transaction(3, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Set the ID to 1 for this transaction
set_id(1, tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
-- Execute the tr_id transaction.
execute_transaction(tr_id, bfm_index, axi4stream_tr_if_0(bfm_index));
Prototype procedure execute_transaction
(
transaction_id : in integer;
