Can I inteface the Ethernet PHY on DE10 Nano directly from the FPGA?

I want to test some Ethercat IP:s on a DE10 Nano board and need two Ethernet interfaces. I would like to use the one already on the board but it seems it only interfaces through the HDS. I will add...

Hi PYtte,

Unfortunately the answer is no. I checked Terasic DE10 nano board user guide doc page 37 and it mentioned on board Micrel PHY chip is connected to Cyclone V FPGA HPS Ethernet MAC block.

So, you need to use HPS Ethernet MAC to interact with this on board PHY chip and not regular FPGA soft TSE IP to talk to the PHY chip.

Thanks.
