FPGA-Board for Ethernet

but, I´ve never worked with FPGAs so I am asking here.

If you don't want to spend a lot of money on tools, I'd recommend any board (with Ethernet) that comes with a device-locked license for the Embedded Edition of ISE. This gives you access to LWIP (light-weight IP) and is likely to come with enough demo apps to make your life easier, whether you intended to use an embedded processor or not.

You might look at Arrow Electronics' BeMicro SDK with usb, 10/100 enet, SD card, MDDR RAM, and a 22K LE Cyclone 4E FPGA, for the peasantly sum of $79. All in a "memory stick" form factor, with an expansion connector on the en d. It is intended for developing applications around their NIOS soft proces sor, but is perfectly useable as an ordinary FPGA.

Spartan 3 or Spartan 6 will work. Try digilentinc.com

Sorry I was not at work the last days. Thank you very much for the answers and your care. I will do as you say and look for a board with Xilinx ISE. The Diligent Boards are looking good. I think it will be the Spartan 3E Starter Board:

Do I need an Gigabit-Ethernet PHY? Do I need 2 RJ-45 Interfaces? Or can I connect the UTP Cable directly the t he FPGA pins. Or something like UTP to RJ-45 and the PC with usb? For further Information about the used ethernet you can look at the Figure 5 its the Broadcom Ethernet

Thank you very much Banko

your care.

If you're doing gigabit Ethernet, then yes. Note that most gigabit PHYs also work at 10 and 100 Mbps.

Depends on what you want to do with it.

You can certainly connect a UTP cable directly to an FPGA (like you could with any piece of wire), but it might not do what you want. High speed Ethernet usually uses a parallel interface (GMII/MII, etc.) that the PHY converts to one of the physical layer Ethernet standards. Most FPGAs aren't capable of generating the correct logic levels necessary for Ethernet directly, which is why you need a PHY.

Not sure what you mean by that!

its the Broadcom Ethernet

If you want to use Automotive Ethernet, I would recommend that you use an Automotive Ethernet PHY. They're not very common on FPGA development boards, so you might need to do some PCB design for this.

ers and your care.

=S3EBOARD

=ATLYS

gure 5 its the Broadcom Ethernet

Thank you. I've got an automtive phy now, so i have to implement the MAC Layer on the FPGA and thats it. I've found the opencores at opencores.org

So Thank you very much :)
