Avalon-MM Master BFM
Send Feedback
The Avalon-MM Master BFM implements the Avalon-MM interface protocol, including: read, write, burst
read, and burst write. The figure below shows the top-level modules for a testbench using the Avalon-MM
BFM to verify an Avalon-MM slave component. The typical testbench includes the folowing components:
• The Avalon-MM Master BFM
• A test program
• The DUT that includes an Avalon-MM slave interface
Using the Avalon-MM BFM created by Altera, third-party, has the following advantage. It highlights any
misinterpretation of the Avalon-MM protocol that might be missed in a testbench designed by a single
engineer.
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.
