A slave BFM has configuration fields that you can set with the
function to
configure timeout factors, slave exclusive support, setup and hold times, etc. You can also get
the value of a configuration field via the
The full list of configuration fields is described in
**_ID_WIDTH
ID signal width in bits. This applies to the RID and WID signals.
Refer to the AMBA AXI Protocol specification for more details.
Default: 4.
AXI4_USER_WIDTH
(AXI4) User data signal width in bits. This applies to the
ARUSER, AWUSER, RUSER, WUSER and BUSER signals.
Refer to the AMBA AXI Protocol specification for more details.
Default: 8.
AXI4_REGION_MAP_SIZE
(AXI4) Region signal width in bits. This applies to the
ARREGION and AWREGION signals. Refer to the AMBA AXI
Protocol specification for more details. Default: 16.

Timing Variables
**_CONFIG_SETUP_TIME
The setup-time prior to the active edge of
ACLK, in units of simulator time-steps for
all signals.
1
Default: 0.
**_CONFIG_HOLD_TIME
The hold-time after the active edge of
ACLK, in units of simulator time-steps for
all signals.
1
Default: 0.
**_CONFIG_MAX_TRANSACTION_
TIME_FACTOR
The maximum timeout duration for a
read/write transaction in clock cycles.
Default: 100000.
AXI_CONFIG_TIMEOUT_MAX_DATA_TRANSFER
(AXI3) The maximum number of write
data beats that the AXI3 BFM can
generate as part of write data burst of
write transfer. Default: 1024.
**_CONFIG_BURST_TIMEOUT_FACTOR
The maximum delay between the
individual phases of a read/write
transaction in clock cycles. Default:
10000.
**_CONFIG_MAX_LATENCY_AWVALID_
ASSERTION_TO_AWREADY
The maximum timeout duration from the
assertion of AWVALID to the assertion of
AWREADY in clock periods (default
10000).
**_CONFIG_MAX_LATENCY_ARVALID_
ASSERTION_TO_ARREADY
The maximum timeout duration from the
assertion of ARVALID to the assertion of
ARREADY in clock periods (default
10000).
