3.6.2. 10GbE Testbench Component
The 10GbE testbench comprises the following modules:
■ Device under test (DUT)—the design example.
■ Avalon driver—uses Avalon-ST bus functional models (BFMs) to exercise the
transmit and receive paths. The driver also utilizes the Avalon-MM BFM to access
the Avalon-MM interfaces of the design example components.
■ Packet monitors—monitors the transmit and receive datapaths, and displays the
frames in the simulator console.
3.6.3. 10GbE Testbench Files
The following directories contain the 10GbE testbench files which are in clear text:
