Slave BFM Configuration
April 2014
A slave BFM has configuration fields that you set by calling the
configure timeout factors, setup and hold times, and so on. You get the value of a configuration
field by calling the
procedure.
describes the full list of configuration
fields.
AXI4_USER_WIDTH
User data signal width in bits. This applies to the TUSER
signal. Refer to the AMBA AXI4-Stream Protocol
Specification for more details. Default: 8.
AXI4_DEST_WIDTH
Destination routing signal width in bits. This applies to
the TDEST signal. Refer to the AMBA AXI4-Stream
Protocol Specification for more details. Default: 18.
AXI4_DATA_WIDTH
Data signal width in bits. This applies to the TDATA
signal. Refer to the AMBA AXI4-Stream Protocol
Specification for more details. Default: 1024.

Description
Timing Variables
AXI4STREAM_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.
AXI4STREAM_CONFIG_HOLD_TIME
The hold-time after the active
edge of ACLK, in units of
simulator time-steps for all
signals.
1
Default: 0.
AXI4STREAM_CONFIG_BURST_TIMEOUT_FACTOR
The maximum delay between
individual transfers in clock
cycles. Default: 10000.
AXI4STREAM_CONFIG_MAX_LATENCY_TVALID_
ASSERTION_TO_TREADY
The maximum delay permitted
between the assertion of
TVALID to the assertion of
TREADY. Default: 10000.
Master Attributes
AXI4STREAM_LAST_DURING_IDLE
Controls the value of TLAST
during idle.
0 = TLAST driven to 0 during
idle (default)
1 = TLAST driven to 1 during
idle
