how to do pin assignment with Ethernet IP

HI,everybody.

I am wondering how to do pin assignment with my board , cycone II, using magawizard ethernet IP. I watched the input and output signals after completing the ip core ,so many signals that I can't assign them with pins on board. Some people said that quartus can do such a task , is that reliable?

I appreacite any advive.

    Are you sure you used the correct IP for the correct chip? What Ethernet chip do you have on the board and which IP did you use?

    i am not sure, iam the beginner to use Ethernet IP core. The chip in the Cyclone ii EP2C35 belongs to SMSC(MAC+PHY) which only support 10/100BASE.

    following is the attachment.

    thanks.

    If the chip is the LAN91C111 then you can't use the Triple Speed Ethernet IP with it. The TSE is a MAC that needs to be connected to a PHY, while the LAN91C111 is a chip that includes both the MAC and the PHY.

    There is a component in SOPC builder than can be interfaced with a LAN91C111

    That’s too much help for me. I was wondering how to do pin assigment with LAN91C111 for these days ,and serching for some material but know nothing about it. So ,as you proposed, if TSE(which is a MAC) is created in the form of a ip core, how to do pin assignment with the PHY on board?

    It won't work. The TSE IP can't be interfaced with the LAN91C111 chip.

    If you are using SOPC builder there is a component for the LAN chip that you must use instead of the TSE IP.
