Monitor Assertions

The monitor BFM performs protocol error checking using built-in assertions.

Note

The built-in BFM assertions are independent of programming language and simulator.

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 the
individual phases of a read/write
transaction 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

Error Detection

AXI4STREAM_CONFIG_ENABLE_ALL_ASSERTIONS

Global enable/disable of all
assertion checks in the BFM.
0 = disabled
1 = enabled (default)

AXI4STREAM_CONFIG_ENABLE_ASSERTION

Individual enable/disable of an
assertion check in the BFM.
Refer to
