Example 5-3. Monitor BFM Individual Assertion Enable/Disable
// Define a local bit vector to hold the value of the assertion bit vector
bit [255:0] config_assert_bitvector;
// Get the current value of the assertion bit vector
config_assert_bitvector =
bfm.get_config(AXI4STREAM_CONFIG_ENABLE_ASSERTION);
// Assign the AXI4STREAM_TLAST_CHANGED_BEFORE_TREADY assertion bit to 0
config_assert_bitvector[AXI4STREAM_TLAST_CHANGED_BEFORE_TREADY] = 0;
// Set the new value of the assertion bit vector
bfm.set_config(AXI4STREAM_CONFIG_ENABLE_ASSERTION,
config_assert_bitvector);
Note
Do not confuse the AXI4STREAM_CONFIG_ENABLE_ASSERTION bit vector with
the AXI4STREAM_CONFIG_ENABLE_ALL_ASSERTIONS global enable/disable.
To re-enable the AXI4STREAM_TLAST_CHANGED_BEFORE_TREADY assertion, follow
the code sequence in
Example 5-3 and assign the assertion within the
AXI4STREAM_CONFIG_ENABLE_ASSERTION bit vector to 1.
For a complete listing of AXI4-Stream assertions, refer to “ Assertions ” on page 205.
SystemVerilog Monitor API
This section describes the SystemVerilog monitor BFM API.
Each task and function available within the monitor BFM API is detailed with the exception of
the set*() and get*() tasks that operate on the
Transaction Record . The simple rule for the task
name is set_ or get_ followed by the name of the transaction field to be accessed. Refer to
“
Transaction Record ” on page 23 for details of transaction field names
Note
The monitor BFM API is the axi4stream/bfm//mgc_axi4stream_monitor.sv file packaged
within the Mentor
Verification IP Altera Edition.
