Hello friends, I Have just started going through ethernet.my doubt is what is the main functionality of Ethernet MAC??? In switch controller implementation on FPGA does 4 tranceivers require 4 Ethernet MAC's???if so why??Because the source and the destination systems will have ethernet controller and MAC built in???please answer these questions.It's haunting me. Thanks. Regards, Hema.

Hi all, I want to implement ethernet but I have no exprience about ethernet. Can you please recommend some thing. I can use precessor (M16C) or FPGA. I haven't got FPGA development board yet and maybe i can't buy because i have money problem. I think if I use FPGA I don't need ethernet controller If I can write it :). I have try some projects like as uart, I2C on the Nuhorizons CR2 Developme...

Im a beginer in VHDL and i got some problems regarding Ethernet usage on XST 3.0 Board. I want to send audio trought ethernet to a second XST 3.0 but i have a lot of problems regarding Ethernet interface initialization - I'm not able to sent anything. I will meke some package processing later on but now I cannot even send one frame. Maybe you got some examples of ethernet intercace usage for ...

Hi, Im working on communication for the Virtex 5 using Ethernet. As a good start, do you have any ideas/examples program which use Virtex5? I have tried browsing on the internet, but there are not much about Ethernet Virtex5 example codes. I would be very happy if somebody can guide to show a simple program to communicate using Ethernet-Virtex5. Cheers ------------------------...

Hello everyone, I am trying to implement ethernet MAC on a fpga using vhdl. I have a transmit module which generates the ethernet frame and transmits to the PC through the ethernet cable. The ethernet frame consists of preamble, sfd, destination(MAC), source(MAC), length,data,crc. I am using ethereal to detect this frame I definitely think that my crc is right. But i am not able to de...

Hy guys, I'm currently working on a 10/100 ETHERNET mac implementation in an FPGA (using vhdl). in order to simulate my state machine I need to feed a real ETHERNET packet to it (in order to see if the crc check is exeuted correctly etc.). I will realy appreciate to get a complete ETHERNET packet (all bytes from PREAMBLE to FCS) so I could insert it to my modelsim simulation. the format I'...

Hi All, I have a embedded desig where I communicate with two boards via Fast ethernet. The design is very simple, the packets are generated from a fpga and sent to the ethernet phy on MII. In the new design I'd like to replace the ethernet phy with a VSDL2 chipset, so I need only one twisted pair and for supporting more than 100 m. Has anybody did something similar? IMO it should be very ...

Hello ALL, I am designing device, based on Virtex-4 FX20 chip. This device is going to produce lots of data and I would like to send it to processing computer using Gigabit Ethernet interface. I am lucky to have two Ethernet MAC's built-in in the FPGA. Also we would like to use RocketIO transceivers to connect our Ethernet MAC's to physical media. Here is my problem begins. I need to conne...

hello, I am trying to interface between my pc (windows) and a Xilinx Virtex2Pro board using ethernet. i am told i require Xilinx PLB Ethernet MAC ip core. i must admit i am very new to such work, forgive my blatantness.... i would like to know: 1) What exactly do i get in the Xilinx Ethernet MAC ip core? (design files etc?) 2) Using XPS (EDK 9.1) and ISE 9.1, how do i integrate it int...

Hi, As part of a project my partner and I are required to use the APEX board and the NIOS Ethernet Development Kit for internet communication. We need an indepth understanding of the software code needed to program the ethernet board, e.g. initiallizing, sending, etc. however the manual and online resources don't have alot of information. Is there anyone who has used the ethernet adapt...

Hello everyone, I am sending an ethernet packet(64 bytes) from the fpga to the PC in order to test the ETHERNET PHY chip onboard. The interface from the fpga to the ethernet PHY for the data is 4 bits. My PC mac address is 00-01-80-3F-6C-E6 a)So should i send the LSBs first like in this order, 6,E,C,6,F,3,0,8,1,0,0,0 or the MSBs first b) I have installed ethereal software...

Hello, I need to snooping the ethernet data so that corresponding data is send to corresponding link. I mean one input and two output link (Ethernet). So only way to implement is to buffer the whole ethernet packet and look for the VLAN address and send it to the corresponding path?Is there any other way ? This all need to be implemented in FPGA. Any help will be great appreciated. Thanks...

I don't know that my fpga is capable (spartan 3e 100k), but I thought I might like to try to do ethernet first. I remember finding a tutorial weeks ago but forgot to bookmark it, where the instructions had you hook up two io pins directly to an ethernet cable, and you could hardcode an IP address into the chip and ping it. Does anyone know of any like this, or even of the one I speak? (Might ...

Hi all I want to transfer the data feom the kit to the PC using the 10/100 ethernet. Can any one tell me how it can be done and what are the things required for that? how to configure that. I have an ethernet lite IP core supplied by the Xilinx. If any one has some sample regarding that It would be highly appriciated. thanks in advance. regards Ashish

Hi, (this is my second attempt to get some help on the subject). I am searching for an FPGA board having multiple gigabit ethernet connectivity support on it. To be more precise, I need to have multiple RJ45 connectors and associated logic (PHYs) on the FPGA board so that I can process multiple ethernet streams on the FPGA. Can anyone suggest any such board? or any add-on module which can be ...

Hi, I am the proud new owner of a Virtex XCV50 sitting on a XESS protoboard. I know this is an old system but I want to learn about FPGA's and VHDL with it. Does anyone have a program that I can use to make the Ethernet interface work or perhaps the video inputs. I prefer to have some TCP/IP software so I can connect it to a network and test the ethernet. Any pointers are greatly ...

Hello, Recently I bought an Ethernet Module from your web-site. I have used the recommended vhdl file (dpimref.vhd) to test this Ethernet Module. I placed the code that is used for the leds and buttons in comment because they are not available on the Ethernet Module. When I download this design to a Xilinx Virtex II pro development board and I use the communication software from you ...

hello, i want to capture 2 mbps serial data stream through my ethernet card. i already have a Virtex FPGA based hardware and I want to add it this data logging funtionality. I want to use FPGA to convert the received serial data into ethernet format and dump it onto the ethernet interface. Then i can use some port sniffer to capture that data. i just have the vague idea. kidly someone t...
