SystemVerilog API Overview
Access Transaction Record
September 2013
Note
Not all BFM APIs support the full complement of get*_transaction(), get*_burst(),
get*_phase(), get*_cycle() tasks. Refer to the individual master, slave or monitor BFM
API for details.
Access Transaction Record
Each BFM API has tasks that can access a complete or partially complete Transaction Record .
The set*() and get*() tasks are used in a test program to set and get information from the
transaction record.
Note
The set*() and get*() tasks are not explicitly described in each BFM API chapter. The
simple rule for the task name is set_ or get_ followed by the name of the transaction field
accessed. Refer to
“Transaction Fields” on page 17 for transaction field name details.
set*()
For example, to set the WSTRB write strobes signal for the first phase (beat) in the Transaction
Record of a write transaction, the master test program would use the set_write_strobes() task, as
shown in the code below.
write_trans.set_write_strobes(4'b0010, 0);
get*()
For example, a slave BFM test program uses a received write address phase to get the AWPROT
signal value from the
Transaction Record , as shown in the slave BFM test program code below.
// Define a variable prot_value of type axi_transaction
axi_prot_e prot_value;
slave_trans = bfm.create_slave_transaction();
// Wait for a write address phase
bfm.get_write_addr_phase(slave_trans);
... …
// Get the AWPROT signal value of the slave transaction
prot_value = bfm.get_prot(slave_trans);
