Dir Sir,
I'm using Cyclone III development kit. I want using Ethernet IP with mii standard to transfer data via Ethernet. and I want using 100Mbs standard. However, this kit not support tx_clk from PHY 88E1111. If I want to use 100Mbps, what should I do? I also buy a HSMC-NET of terasic, then I connect this this with Cyclone III via HSMC port. I used tx_clk for my Ethernet. however, tx_clk is not active clock. How to enable clock this pin from PHY 88e1111? Thank you so much.Link Copied

Check if You really have all required wires connected to do MII connection. Maybe there are only wires for RMII?

Then MII should work fine. Are You forcing 1Gbit network to work on 100Mbps? Did You tie 1000Mbps setting in MAC to '0'?

I only want working on 10/100Mbs. therefore, I need 2 clock are tx_clk and rx_clk for the Ethernet-mac. I also built the system on Stratix III kit. However, when i plug Ethernet cable the rx_led and tx_led are not blinking. I's using signal-tab to capture enet_tx_clk and enet_rx_clk are not oscillate

Check PHY reset signal, is it high? Did You implement reset bug-fix? Check 88E1111 PDF for proper PHY initialization setup. You need to de-assert reset at required time.
