11. Avalon Streaming Credit Source BFM

The Avalon Streaming Credit Source BFM implements the Avalon Streaming Credit Interface protocol. The Avalon Streaming Credit Interface protocol is point-to-point, packet-oriented and drives unidirectional data. This BFM component includes a procedural interface to control signals on the Avalon Streaming Credit Interface including update, credit, start of packet, empty, end of packet and other signals.

The following figure shows a top-level module for a testbench. This testbench uses an Avalon Streaming Credit Source BFM to verify an Avalon Streaming Credit Sink component. In addition to the Avalon Streaming Credit Source component, the testbench typically includes a test program and the DUT.

The BFMs may allow certain illegal transactions so that you can test the error-handling functionality of the DUT.
