VHDL Monitor BFM

This section provides information about the VHDL monitor BFM. It has an API that contains

procedures to configure the BFM and to access the dynamic Transaction Record during the life

of the 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 within 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. The monitor has access to all the facilities provided by the

monitor BFM.

Monitor BFM Protocol Support

The monitor BFM supports the full AMBA AXI4-Stream protocol.

Monitor Timing and Events

For detailed timing diagrams of the protocol bus activity, refer to the relevant AMBA

AXI4-Stream Protocol Specification chapter, which you can reference for details of the

following monitor BFM API timing and events.

The AMBA AXI4-Stream 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
