April 2014
get_addr()
This nonblocking procedure gets the start address addr field for a transaction that is uniquely
identified by the transaction_id field previously created by either the
create_write_transaction() or create_read_transaction() procedure.
Example
-- Create a read transaction with start address of 1.
-- Creation returns tr_id to identify the transaction.
create_read_transaction(1, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
....
-- Get the start address addr of the tr_id transaction
get_addr(addr, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
