9. Avalon-ST Sink BFM

The Avalon-ST Sink BFM implements the Avalon-ST interface protocol. The Avalon-ST protocol is point-to-point, packet oriented, and drives unidirectional data. This BFM component also includes a procedural interface to respond to the DUT that includes an Avalon-ST source interface. The following figure shows the top-level modules for testbench that uses the Avalon-ST Sink BFM to verify an Avalon-ST source device. In addition to the Avalon-ST Sink BFM component, the testbench includes a test program and the DUT.
Note: The BFMs allow illegal transactions so that you can test the error-handling functionality of your DUT. Consequently, the BFMs cannot be relied upon to guarantee protocol compliance. The Avalon Monitor components verify protocol compliance.
