**_CONFIG_MAX_LATENCY_RVALID_

ASSERTION_TO_RREADY

The maximum timeout duration from the
assertion of RVALID to the assertion of
RREADY
in clock periods (default
10000).

**_CONFIG_MAX_LATENCY_BVALID_

ASSERTION_TO_BREADY

The maximum timeout duration from the
assertion of BVALID to the assertion of
BREADY
in clock periods (default 10000).

**_CONFIG_MAX_LATENCY_WVALID_

ASSERTION_TO_WREADY

The maximum timeout duration from the
assertion of WVALID to the assertion of
WREADY in clock periods (default
10000).

AXI_CONFIG_WRITE_CTRL_TO_DATA_MINTIME

(AXI3) The minimum delay from the start
of a write control (address) phase to the
start of a write data phase in clock cycles.
Default: 1.

AXI_CONFIG_MASTER_WRITE_DELAY

(AXI3) The master BFM applies the
AXI_CONFIG_WRITE_CTRL_TO_
DATA_MINTIME value set.

0 = true (default)
1 = false

AXI_CONFIG_MASTER_DEFAULT_UNDER_RESET

(AXI3) The master BFM drives the
ARVALID, AWVALID and WVALID
signals low during reset:

0 = false (default)
1 = true

Slave Attributes

AXI4_CONFIG_ENABLE_QOS

(AXI4) The master participates in the
Quality-of-Service scheme. If a master
does not participate, the
AWQOS/ARQOS value used in
write/read transactions must be b0000.

**_CONFIG_SUPPORT_EXCLUSIVE_ACCESS

Configures the support for an exclusive
slave. If enabled the BFM will expect an
EXOKAY response to a successful
exclusive transaction. If disabled the BFM
will expect an OKAY response to an
exclusive transaction. Refer to the AMBA
AXI protocol specification for more
details.

0 = disabled
1 = enabled (default)

AXI_CONFIG_SLAVE_DEFAULT_UNDER_RESET

(AXI3) The slave BFM drives the BVALID
and RVALID signals low during reset.
Refer to the AMBA AXI Protocol
specification for more details.
