Creating a custom IP block in Vivado. Update 2. 01. 7 1. Heres a newer tutorial on creating a custom IP with AXI Streaming interfaces. Tutorial Overview. In this tutorial well create a custom AXI IP block in Vivado and modify its functionality by integrating custom VHDL code. Well be using the Zynq So. C and the Micro. Zed as a hardware platform. Platform Cable USB II DS593 v1. June 23, 2015 www. Xilinxs Embedded Development. HTB1W1SMGFXXXXbKXFXXq6xXFXXXo/221430014/HTB1W1SMGFXXXXbKXFXXq6xXFXXXo.jpg' alt='Platform Cable Usb Ii Xilinx Vivado' title='Platform Cable Usb Ii Xilinx Vivado' />For simplicity, our custom IP will be a multiplier which our processor will be able to access through register reads and writes over an AXI bus. The multiplier takes in two 1. A single 3. 2 bit write to the IP will contain the two 1. A single 3. 2 bit read from the peripheral will contain the result from the multiplication of the two 1. The design doesnt serve much purpose, but it is a good example of integrating your own code into an AXI IP block. Requirements. Before following this tutorial, you will need to do the following Vivado 2. Micro. Zed. Platform Cable USB II or equivalent JTAG programmerStart from a base project. HTB1SU1ALXXXXXcCXFXXq6xXFXXXq/Xilinx-Platform-USB-font-b-Download-b-font-Cable-Jtag-Programmer-for-FPGA-CPLD-XC2C256.jpg' alt='Platform Cable Usb Ii Xilinx Vivado' title='Platform Cable Usb Ii Xilinx Vivado' />Advanced Micro Devices, Inc. AMD is an American multinational semiconductor company based in Sunnyvale, California, United States, that develops computer processors. You can do this tutorial with any existing Vivado project, but Ill start with the base system project for the Micro. Zed that you can access here Base system project for the Micro. Zed. Create the Custom IPWith the base Vivado project opened, from the menu select Tools Create and package IP. The Create and Package IP wizard opens. If you are used to the ISEEDK tools you can think of this as being similar to the CreateImport Peripheral wizard. Click Next. On the next page, select Create a new AXI4 peripheral. Click Next. Now you can give the peripheral an appropriate name, description and location. Click Next. On the next page we can configure the AXI bus interface. For the multiplier well use AXI lite, and itll be a slave to the PS, so well stick with the default values. On the last page, select Edit IP and click Finish. Another Vivado window will open which will allow you to modify the peripheral that we just created. At this point, the peripheral that has been generated by Vivado is an AXI lite slave that contains 4 x 3. We want to add our multiplier code to the IP and modify it so that one of the registers connects to the multiplier inputs and another to the multiplier output. ZedBoard is a complete development kit for designers interested in exploring designs using the Xilinx Zynq7000 All Programmable SoC. The board contains all the. Add the multiplier code to the peripheral. You can find the multiplier code on Github at the link below. Download the multiplier. Vivadoiprepomymultiplier1. Note that these steps must be done in the Vivado window that contains the peripheral we just created not the base project. From the Flow Navigator, click Add Sources. In the window that appears, select Add or Create Design Sources and click Next. On the next window, click Add Files. Browse to the multiplier. OK. Make sure you tick Copy sources into IP directory and then click Finish. The multiplier code is now added to the peripheral, however we still have to instantiate it and connect it to the registers. Modify the Peripheral. At this point, your Project Manager Sources window should look like the following Open the branch mymultiplierv. Double click on the mymultiplierv. S0. 0AXIinst file to open it. The source file should be open in Vivado. Find the line with the begin keyword and add the following code just above it to declare the multiplier and the output signal signal multiplierout stdlogicvector3. VECTOR1. 5 downto 0. VECTOR1. 5 downto 0. VECTOR3. 1 downto 0. Now find the line that says Add user logic here and add the following code below it to instantiate the multiplier multiplier0 multiplier. SAXIACLK. a slvreg. Find this line of code regdataout lt slvreg. In the process statement just a few lines above, replace slvreg. Save the file. You should notice that the multiplier. Click on IP File Groups in the Package IP tab of the Project Manager. Click the Merge changes from IP File Group Wizard link. The IP File Groups should now have a tick. Now click Review and Package IP. Now click Re package IP. The peripheral will be packaged and the Vivado window for the peripheral should be automatically closed. We should now be able to find our IP in the IP catalog. Now the rest of this tutorial will be done from the original Vivado window. Add the IP to the design. Click the Add IP icon. Find the mymultiplier IP and double click it. The block should appear in the block diagram and you should see the message Designer Assistance available. Run Connection Automation. Click the connection automation link. Click the mymultiplier0 peripheral from the drop down menu. In the window that appears, set Clock connection to Auto and click OK. The new block diagram should look like this Generate the bitstream. When the bitstream is generated, select Open the implemented design and click OK. Export the hardware design to SDKOnce the bitstream has been generated, we can export our design to SDK where we can then write code for the PS. The PS is going to write data to our multiplier and read back the result. In Vivado, from the File menu, select Export Export hardware. In the window that appears, tick Include bitstream and click OK. Again from the File menu, select Launch SDK. In the window that appears, use the following settings and click OK. At this point, the SDK loads and a hardware platform specification will be created for your design. You should be able to see the hardware specification in the Project Explorer of SDK as shown in the image below. You are now ready to create a software application to run on the PS. Create a Software application. At this point, your SDK window should look somewhat like this To make things easy for us, well use the template for the hello world application and then modify it to test the multiplier. Lietuviska Muzika 2010. From the File menu, select New Application Project. In the first page of the New Project wizard, choose a name for the application. Ive chosen helloworld. Click Next. On the templates page, select the Hello World template and click Finish. The SDK will generate a new application which you should find in the Project Explorer as in the image below. The helloworld folder contains the Hello World software application, which we will modify to test our multiplier. Modify the Software Application. Now all we need to do is modify the software application to test our multiplier peripheral. From the Project Explorer, open the helloworldsrc folder. Open the helloworld. Replace all the code in this file with the following. Xuint. 32 baseaddrp Xuint. XPARMYMULTIPLIER0S0. AXIBASEADDR. initplatform. Multiplier Testnr. Write multiplier inputs to register 0. Wrote 0x0. 8x nr, baseaddrp0. Read multiplier output from register 1. Read 0x0. 8x nr, baseaddrp1. End of testnnr. Save and close the file. Test the design on the hardware. To test the design, we are using the Micro. Zed board from Avnet. Make the following setup before continuing On the Micro. Zed, set the JP1, JP2 and JP3 jumpers all to the 1 2 position. Connect the USB UART J2 to a USB port of your PC. Connect a Platform Cable USB II programmer or similar device to the JTAG connector. Connect the programmer to a USB port of your PC. Now you need to open up a terminal program on your PC and set it up to receive the test messages. I use Miniterm because Im a Python fan, but you could use any other terminal program such as Putty.
