Tutorial Overview

The Virtex-5 Embedded Tri-mode Ethernet MAC is useful for designs requiring Ethernet connectivity. Fortunately, Xilinx has made it easy for us to start developing with the Ethernet MACs by providing several online examples and application notes. One of the examples can be obtained when you use CORE Generator to generate the Ethernet MAC wrapper. The generated example is a simple design that mirrors incoming Ethernet packets, swapping the source and destination MAC addresses. In this tutorial, we implement the example design provided by CORE Generator by working the example code into a custom peripheral for EDK 10.1.

This tutorial contains screenshots to guide you through the entire implementation process. Click on the images to view a higher resolution.

Requirements

Before following this tutorial, you will need to do the following:

• Generate the Virtex-5 Embedded Tri-mode Ethernet MAC Wrapper using CORE Generator. For instructions on doing this, please refer to the tutorial Generating the Ethernet MAC
• Set the J22 and J23 jumpers on the ML505 to positions 2-3 as shown below. This allows us to use an SGMII (serial) interface with the PHY.
• Install a copy of Wireshark on a PC with a Gigabit Ethernet network card
• Obtain a CAT5 Ethernet cable: regular or crossover, either will work because the PHY on the ML505 has an automatic switching feature that detects what type of cable you are using and switches the TX and RX pins if necessary.
• Buy an ML505/ML506/ML507 or XUPV5 board if you don't already have one. Xilinx supplies the ML50x boards, but the best deal is the XUPV5 from Digilent. Click the Digilent link on this page for more information.

Create the Basic Project

Follow these steps to create the basic project: https://heregload393.weebly.com/network-logger-3-3-active-network-testing-tool.html.

1. Open XPS. From the dialog box, select 'Base System Builder wizard' and OK.
2. You will be asked to specify which folder to place the project. Click 'Browse' and create a new folder for the project. Click 'OK'.
3. We are given the choice to create a new project or to create one using the template of another project. Tick 'I would like to create a new design' and click 'Next'.
4. On the 'Select Board' page, select 'Xilinx' as the board vendor. Select 'Virtex 5 ML505 Evaluation Platform' as the board name. Select '1' as the board revision. Click 'Next'.
5. On the 'Select Processor' page, we normally have a choice between using the PowerPC 'hard' processor, or the Microblaze 'soft' processor. Since the Virtex-5 does not contain any PowerPCs, we can only select Microblaze. Click 'Next'.
6. On the 'Configure Microblaze' page, select the clock frequency to be 125MHz. For the BRAM local memory, select '64KB'. We will use the RS232 port for debugging rather than the JTAG, so select 'No debug'. Click 'Next'.
7. In selecting the Additional IO Interfaces, leave RS232_Uart_1 ticked and un-tick everything else.
8. On the 'Add Internal Peripherals' page, click 'Next'.
9. On the 'Software Setup' page, select RS232_Uart_1 for both STDIN and STDOUT. Un-tick 'Memory Test' and leave 'Peripheral Test' ticked. Click 'Next'.
10. Click 'Generate'.
11. Click 'Finish'.

Create the Ethernet MAC Peripheral

We now create our Ethernet MAC peripheral using the Peripheral Wizard.

1. Select from the menu 'Hardware->Create or Import Peripheral'. Click 'Next'.
2. Select 'Create templates for a new peripheral' and click 'Next'.
3. We must now decide where to place the files for the peripheral. They can be placed within this project, or they can be made accessible to other projects. Select 'To an XPS project'. Click 'Next'.
4. On the 'Name and Version' page, type eth_mac for the peripheral name. Click 'Next'.
5. On the 'Bus Interface' page, select 'Processor Local Bus' (PLB) and click 'Next'.
6. On the 'IPIF Services' page, select 'Include data phase timer'. Un-tick everything else and click 'Next'.
7. On the 'Slave Interface' page, leave the defaults and click 'Next'.
8. On the 'Peripheral Simulation Support' page, we can specify if we want the wizard to create a simulation platform for our peripheral. Click 'Next' without ticking the option to generate.
9. After the 'Peripheral Implementation Support' page, the wizard will generate all the template files for us. Tick 'Generate ISE and XST project files' and 'Generate template driver files'. Click 'Next'.
10. Click 'Finish'. Now our templates are created and we can modify them to include the code for the timer.

Copy the Ethernet MAC source files

We need to copy the Ethernet MAC source files generated by CORE Generator into the Ethernet MAC peripheral source folder. If you have not generated the source files using CORE Generator, please refer to the tutorial Generating the Ethernet MAC.

1. Open Windows Explorer and browse to the folder TEMACCorev5_emac_v1_5. This is the folder you created with CORE Generator.
2. In that folder, you will find a subfolder called example_design. Copy the example_design folder into the pcoreseth_mac_v1_00_ahdlvhdl folder within your XPS project. This is the folder where you should find your user_logic.vhd file for the Ethernet MAC peripheral.

Modify the .PAO file

The .pao file contains a list of all the source files that compose our peripheral. We use this list when we run the Peripheral Wizard in Import mode. Now that we have added the Ethernet MAC example source files to the project, we must include them in the .pao file. Note that files must be listed in the .pao file in hierarchical order. The components at the top of the hierarchy are listed at the bottom of the file.

1. Select 'File->Open' and browse to the pcoreseth_mac_v1_00_adata folder. Select the file eth_mac_v2_1_0.pao and click 'Open'.
2. At the bottom of this file you will see these two lines:

1. Add the following lines just above those two lines. It is important to copy the lines exactly as shown and in the same order.

1. Save the file.

Now we can use this .pao file with the Peripheral Wizard when we import the Ethernet MAC peripheral.

Modify the Ethernet MAC Peripheral

If you refer back to the example design source files created by CORE Generator, you will find the top module contained in the file v5_emac_v1_5example_designv5_emac_v1_5_example_design.vhd. We copied that file into our peripheral source folder, but we wont directly use it in our design (notice that we didn't include it in our .pao file). Instead, we will take the code from this file and work it into our user_logic.vhd file, the top module for our peripheral.

1. Select from the menu 'File->Open' and look in the project folder.
2. Open the folders: pcoreseth_mac_v1_00_ahdlvhdl.
3. Open the file eth_mac.vhd.
4. Find the line of code that says -- ADD USER PORTS BELOW THIS LINE and add the following lines of code just below.

1. Find the line of code that says -- MAP USER PORTS BELOW THIS LINE and add the following lines of code just below.

1. Save and close the file.
2. Open the file user_logic.vhd. We will need to modify this source code to include our example code.
3. Find the line of code that says --USER libraries added here and add the following lines of code just below.

1. Find the line of code that says -- ADD USER PORTS BELOW THIS LINE and add the following lines of code just below.

1. Find the line of code that says --USER signal declarations added here and add the following lines of code just below.

1. Find the line of code that says --USER logic implementation added here and add the following lines of code just below.

1. Save and close the file.

If you examine the v5_emac_v1_5_example_design.vhd from the CORE Generator output, you will see that most of the code we inserted into user_logic.vhd was directly copied from the example code. The main differences are:

• PHY Reset: We needed to add a signal (PHY_RESET_0) to drive the external Ethernet PHY reset pin. The PHY on the ML505 board has an active low reset input, so we connect it to the logical 'not' of the bus reset signal.
• The clock signal names were changed for clarity. Most Xilinx documents refer to these clocks as REFCLK and USERCLK.

Import the Ethernet MAC Peripheral

Now we will use the Peripheral Wizard again, but this time using the import function.

1. Select from the menu 'Hardware->Create or Import Peripheral' and click 'Next'.
2. Select 'Import existing peripheral' and click 'Next'.
3. Select 'To an XPS project', ensure that the folder chosen is the project folder, and click 'Next'.
4. For the name of the peripheral, type eth_mac. Tick 'Use version' and select the same version number that we originally created. Click 'Next'. It will ask if we are willing to overwrite the existing peripheral and we should answer 'Yes'.
5. Tick 'HDL source files' and click 'Next'.
6. Select 'Use existing Peripheral Analysis Order file (*.pao)' and click 'Browse'. From the project folder, go to pcoreseth_mac_v1_00_adata and select the eth_mac_v2_1_0.pao file. Click 'Next'.
7. On the 'HDL analysis information' page, click 'Next'. The wizard will mention if any errors are found in the design.
8. On the 'Bus Interfaces' page, tick 'PLB Slave' and click 'Next'.
9. On the 'SPLB: Port' page, click 'Next'.
10. On the 'SPLB: Parameter' page, click 'Next'.
11. On the 'Identify Interrupt Signals' page, untick 'Select and Configure Interrupts' and click 'Next'.
12. On the 'Parameter Attributes' page, click 'Next'.
13. On the 'Port Attributes' page, click 'Next'.
14. Click 'Finish'.

The Ethernet MAC peripheral is now ready to use and it should be accessible through the 'IP Catalog->Project Local pcores' in the XPS interface. Note that although we can access it through the IP Catalog, other projects will not find it there because it is only associated with our project, as we specified in the Peripheral Wizard.

Create an Instance of the Peripheral

Now we are ready to create an instance of the peripheral into our project.

1. From the 'IP Catalog' find the eth_mac IP core in the 'Project Local pcores' group. Right click on the core and select 'Add IP'.
2. From the 'System Assembly View' using the 'Bus Interface' filter, connect the eth_mac_0 to the PLB bus.
3. Click on the 'Ports' filter. Click on the '+' for eth_mac_0 to view its ports.
4. Click on the 'Net' field for the PHY_RESET_0 port. Type PHY_RESET_0 in this field and press 'Enter'. Now click again the same field and open the drop down menu. Select 'Make External' and press 'Enter'.
5. Click on the 'Net' field for the GTP_READY port. Type GTP_READY in this field and press 'Enter'. Now click again the same field and open the drop down menu. Select 'Make External' and press 'Enter'.
6. Click on the 'Net' field for the REFCLK_P_IN port. Type REFCLK_P_IN in this field and press 'Enter'. Now click again the same field and open the drop down menu. Select 'Make External' and press 'Enter'.
7. Click on the 'Net' field for the REFCLK_N_IN port. Type REFCLK_N_IN in this field and press 'Enter'. Now click again the same field and open the drop down menu. Select 'Make External' and press 'Enter'.
8. Click on the 'Addresses' filter. Change the 'Size' for eth_mac_0 to 64K. Then click 'Generate Addresses'.

Now we have created an instance of the Ethernet MAC peripheral in our design.

Modify the Constraints file

The Ethernet MAC peripheral requires timing and pin constraints, as well as a constraint to select the RocketIO GTP we will use for a link to the PHY. The clocks used must be constrained to 125MHz while the PHY reset and GTP ready signals must be assigned to specific pins. The GTP and pins that we select here were obtained from the schematic for the ML505.

1. Click the 'Project' tab and double click on the UCF file to open it.
2. Add the following lines to the end of the file:

1. Save and close the file.

Modify the Software Application

In this example, our software application will not do anything other than send a message to Hyperterminal to let you know that it is running. All processing of Ethernet packets is done in hardware through the Ethernet MAC peripheral.

1. From the 'Applications' tab, open 'Sources' within the 'Project: TestApp_Peripheral' tree. Open the TestApp_Peripheral.c source file.
2. Replace all the code in this file with the following source and save the file.

Download and Test the Project

1. Open a Hyperterminal window with the required settings. For the correct settings, see Hyperterminal Settings.
2. Turn on the ML505 board.
3. From the XPS software, select 'Device Configuration->Download Bitstream'.

The Hyperterminal output should display the message 'Tri-mode Ethernet MAC Loop-back by FPGA Developer'. When you get this message, you can continue with the following steps.

1. Open Wireshark on the PC to be used for testing. You can use any PC with a Gigabit Ethernet network card installed and working.
2. From the menu select 'Edit->Preferences'. In the dialog box that opens, select 'User Interface->Columns' and set the columns as shown in the screenshot below. Then click 'OK'.
3. From the menu select 'Capture->Options'. In the dialog box that opens, select the Gigabit Ethernet network card to which you will connect the ML505, then click 'Start'.
4. Connect the CAT5 Ethernet cable between the ML505 and the PC running Wireshark.
5. You should notice that the Ethernet connection LEDs light up on both the ML505 and the PC. The connection LEDs on the PC should be on the Ethernet (RJ45) connector on the back of your PC. The connection LEDs on the ML505 are located next to the PCI edge connector and they are shown in the photo below. In order from left to right, as shown in the photo, the LEDs indicate: CONNECTION, TX, RX, 10Mbps, 100Mbps, 1000Mbps.
6. We will produce Ethernet packets from the PC by using 'ping'. From Windows, select 'Start->Run' and type cmd. Press 'Enter' and you should have a command prompt. From the command line, type ping www.google.com. Note that even before running 'ping', you may already see Ethernet packets in Wireshark. This can happen when your PC is trying to connect to a network.
7. Observe the packets in Wireshark by clicking on them. In the screenshot below, we see that the PC sent packets 1, 3 and 5, while the ML505 sent back packets 2, 4 and 6 with the MAC destination and source addresses swapped. Notice also the short time delay of 225us between the sent packet and the received copy.
8. Also observe that the RX and TX LEDs on the ML505 will light up at the same time, indicating that each packet received is immediately transmitted back to the sender (after swapping the MAC sender/destination addresses).

You can download the project files for this tutorial and try it on your ML50x board. Please select the file corresponding to your board, right-click on it and select 'Save Link As'.

Paste mac. You now have a working Ethernet connection running at 1Gbps. To develop the project further, remove the address swap module and try some of these ideas:

• TCP/IP stack: Connect the Ethernet MAC LocalLink interface to read/write FIFOs and run a TCP/IP stack on the Microblaze. A lightweight TCP/IP stack for the Microblaze is discussed in the application note XAPP1026.
• Ethernet-to-Aurora Bridge: Add an Aurora core to the design and create a transparent bridge.
• Gigabit PC interface: Don't bother with TCP/IP and use the Ethernet MAC for a high-speed PC link.
• Video/audio processing: Use VLC Media Player to stream video into the Virtex-5, then process it and send it out of the DVI interface.

Mac Laptop Tutorial

Remember that the interface to the Ethernet MAC is LocalLink, so you can virtually hook up anything with an 8-bit wide LocalLink interface.
