-- Define a local bit vector to hold the value of the assertion bit vector
variable config_assert_bitvector : std_logic_vector(AXI4_MAX_BIT_SIZE-1
downto 0);
-- Get the current value of the assertion bit vector
get_config(AXI4_CONFIG_ENABLE_ASSERTION, config_assert_bitvector,
bfm_index, axi4_tr_if_0(bfm_index));
-- Assign the AXI4_AWADDR_CHANGED_BEFORE_AWREADY assertion bit to 0
config_assert_bitvector(AXI4_AWADDR_CHANGED_BEFORE_AWREADY) := ‘0’;
-- Set the new value of the assertion bit vector
set_config(AXI4_CONFIG_ENABLE_ASSERTION, config_assert_bitvector,
bfm_index, axi4_tr_if_0(bfm_index));
Note
Do not confuse the AXI4_CONFIG_ENABLE_ASSERTION bit vector with the
AXI4_CONFIG_ENABLE_ALL_ASSERTIONS global enable/disable.
To re-enable the AXI4_AWADDR_CHANGED_BEFORE_AWREADY assertion, following the
above code sequence, assign the assertion in the AXI4_CONFIG_ENABLE_ASSERTION bit
vector to 1.
For a complete listing of assertions, refer to
