VHDL Monitor BFM
This chapter provides information about the VHDL monitor BFM. Each BFM has an API
containing procedures that configure the BFM and access the dynamic
Transaction Record
during the lifetime of a transaction.
Inline Monitor Connection
The connection of a monitor BFM to a test environment differs from that of a master and slave
BFM. It is wrapped in an inline monitor interface and connected inline, between a master and
slave, as shown in
Figure 10-1 . It has separate master and slave ports and monitors protocol
traffic between a master and slave. By construction, the monitor has access to all the facilities
provided by the monitor BFM.

Monitor BFM Protocol Support
The AXI4-Lite monitor BFM supports the AMBA AXI4-Lite protocol with restrictions detailed
in “
Protocol Restrictions ” on page 17.
Monitor Timing and Events
For detailed timing diagrams of the protocol bus activity and details of the following monitor
BFM API timing and events, refer to the relevant AMBA AXI Protocol Specification chapter,
The AMBA AXI Protocol Specification does not define any timescale or clock period with
signal events sampled and driven at rising ACLK edges. Therefore, the monitor BFM does not
