Access Transaction Record
Each BFM API has procedures that can access a complete or partially complete Transaction
Record . The set*() and get*() procedures are used in a test program to set and get information
from the transaction record.
set*()
Example 7-9 shows the master test program calling the set_byte_type() procedure to set the first
byte_type in the transaction.
Example 7-9. Master Test Program set_byte_type() Procedure
-- Define a local variable trans to hold the transaction record.
variable trans: integer;
-- Create a master transaction with 10 transfers.
create_master_transaction(10, trans, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Set the first byte_type in the transfer.
set_byte_type(AXI4STREAM_DATA_BYTE, 0, trans, bfm_index,
axi4stream_tr_if_0(bfm_index));
In the above example, the bfm_index specifies the actual master BFM.
get*()
Example 7-10 shows the slave test program calling the get_byte_type() procedure to get the first
data byte_type of a transaction.
Example 7-10. Slave Test Program get_byte_type() Procedure
-- Define a local variable trans to hold the transaction record.
variable trans: integer;
-- Define a local variable to hold the transaction byte type
variable byte_type: integer;
-- Create a slave transaction
create_slave_transaction(trans, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the first byte_type of a transaction.
get_byte_type(byte_type, 0, trans, bfm_index,
axi4stream_tr_if_0(bfm_index));
In the above example, the bfm_index specifies the actual slave BFM.
