  | Component | Description | 
|---|---|
| Device under test (DUT) | The F-Tile 25G Ethernet IP core. | 
| Ethernet Packet Generator and Packet Monitor | 
 | 
| SYS PLL | Generates clock for the Agilex™ 7 I-Series SoC 25G transceiver which is wrapped in the F-Tile 25G Ethernet IP. | 
| Dynamic reconfiguration controller | If you generate the single-channel design example with dynamic reconfiguration, this IP is automatically instantiated. |
