The 25G Ethernet Intel® FPGA IP core testbench is self-contained and does not require you to drive any input signals.
| Signal | Direction | Comments | 
|---|---|---|
| clk100 | Input | Drive at 100 MHz. The intent is to drive this from a 100 Mhz oscillator on the board. | 
| clk_ref | Input | Drive at 644.53125 MHz or 322.265625 MHz from an oscillator on the board. | 
| cpu_resetn | Input | Resets the IP core. Active low. Drives the global hard reset csr_reset_n to the IP core. | 
| tx_serial | Output | Transceiver PHY output serial data. | 
| rx_serial | Input | Transceiver PHY input serial data. | 
| user_led[7:0] | Output | Status signals. The hardware design example connects these bits to drive LEDs on the target board. Individual bits reflect the following signal values and clock behavior:
