  1. Memory tutorial

    Hi I am beginning my foray into FPGA design, and I decided that the best to to learn would be to learn on the go, and learn as I go. I am using a Zybo Z7 7020, Windows 10, and Vivado 16.4 I have a project for school which will be using PMODs as IOs and the information will have to be saved to memory of the board I am wondering if there is a good tutorial which will help me learn how to access, read and write to the DDR3
  2. I have an Arty-35 evaluation board that came with a device-locked, node-locked Vivado license. (BTW, the board and tools are very nice). Does my limited Vivado license also cover programming the Cmod A7: Breadboardable Artix-7 FPGA Module which also uses an Artix-7 A7-35T FPGA component? I think they're the same Artix-7 device, so it seems like it should work. I'd like to purchase one of these Cmod A7 FPGA DIP devices, but I want to be sure my Vivado license will cover it.
  3. Which version of Vivado should I use

    Hi! I am new to this and I have a project for school so this will be the first of many questions I have a Zybo Z7 7020 and I am running Windows 10 For now, I plan on using the free version of Vivado. My project will involve using the PMOD as IO and using the HDMI output. I understand that in order to program the Zybo, I need the board files and the library files in order to use the IPs In order to have the best compatibility, which version of Vivado should I use? Does it matter? Why?
  4. I need a few units of a development kit, the less expensive, which can provide partial and full dynamic reconfiguration. Also, I would like to know if such board works with microblaze. Can anybody indicate a good product? From Digilent?
  5. Vivado not finding Arty target

    I've installed Vivado v2017.4 on a CentOS 7.4 system. The ARTY board JTAG/UART is connected to a USB port on the host system. When I start Vivado, and start the Hardware Manager, it shows that there is a server running on "localhost" but does not list any target boards. Clicking on "Auto Connect" does nothing. The Hardware Server Properties window says that Vivado is connected to the server. Running "lsusb" on the host shows two ftdi_sio USB Serial Devices which are attached to /dev/ttyUSB0 and /dev/ttyUSB1. Any suggestions?
  6. FPGA Initialization failed

    getting a error while i am trying to program FPGA (zybo) with Pmod:ACL in Xilinx sdk.
  7. [Help/Advice] Read address from DDR and print it

    Hi, i would like to just be able to read memory addresses from RAM on my Zybo Zynq -7000. I have read some interesting articles including this one I followed every step but I'm still missing the part where i can e.g. just read an address print it out (and write it back?). If this could be done with the SDK in c/c++ it'd be awesome . Could anyone recommend me some literature or is there a tutorial which i can follow to understand this better ? Thanks in advance
  8. Zybo placing error

    i'm trying to make a pwm module that i want to use later with the sdk the module has two 32 bit inputs, the first is pwm up time and the second is pwmperiod the simulation is good but when i tried to implement the design, i had an placing error ( number of unplaced terminals is greater ....) as i understand vivado tries to give the two inputs a port with 64 bits my purpose is to assign a value to them from the sdk i tried declaring them as wires, integers, reg same error module pwm( input clk, input enable, output pwm_out, input [31:0] pwm_val, input [31:0] pwm_period ); the log file is attached , thank you implem_log.txt
  9. Hi every one. I was Created HLS Ip Core. This Core is a simple Image Filer, and the input for this Core is a matrix of picture that I built in Matlab, Now I'm trying to have a input from HDMI and filter output from VGA. In other words, I don't know "How create a simple block design in ZYBO for have HDMI input, VGA output and HLS IP CORE?" and "Which commands need to read frames from input in SDK sowftware?" Best regards. Abish SJ
  10. Best Vivado license option on Zedboards

    Hello I want to buy a Zedboard to evaluate to possibly replacing our existing embedded computer solution (Kontron ETX computer module on a baseboard) with a ZYNQ 7000 based solution. I work at a research institute with a very strong mandate to train students. We will probably put a student on this job to investigate, so we might be able to qualify for the Academic edition of the Zedboard. My question is related to the licenses (vouchers) that come bundled with the zedboards by the various resellers. 1. On the site they state: A. (AES-Z7EV-7Z020-G) ZedBoard Commercial Edition (Available Exclusively from Avnet) I have contacted local Avnet rep which stated that this board comes with the Vivado HL Design edition node lock licence valid for 1 year. B. (ZEDBOARD) ZedBoard Academic Edition (Available Exclusively from Digilent) I have contacted digilent which indicate that this board comes with a node locked SDSoC licence valid for 1 year. 2. Looking at other suppliers like Digikey and Mouser ( you find -when searching the datasheet- that they provide a voucher for Chipscope licence only. You use webpack with these boards. Now I know that Vivado Webpack should be enough but I want to maximize value by purchasing the most valuable license for our particular application. I would want the student to have maximum flexibility. I think elements that are important are. 1. Good simulation and debugging capabilities i.e. embedded logic analyser, chipscope and a version of ISIM with more features than that shipped with webpack. 2. Good tools for C/C++ software development. We would be looking at integrating EPICS in our solutions. 3. Also access to more IP cores not available in Webpack would also be interesting to evaluate. We would be looking at integrating EtherCAT into our solutions. 4. It would also be nice to do High Level synthesis work (HLS) using C. Please advise me on which resellers' product supply the best/most valuable licensing option. Thank you Chris

  12. How to connect DMA with microblaze ?

    Hello, I've been doing a few beginner experiments with AXI peripherals and following some tutorials online on how to create AXI peripherals and implement on my Kintex board. So far, I've managed to successfully create a simple custom hardware block and connect it via AXI4-Lite. For counter program, Created a new design on Vivado includes AXI Stream data FIFO, AXI Stream FIFO, microblaze and aurora, and through in XSDK, I wrote C codes for counter program and executed. Its working Fine. Help : I need to add DMA into the counter design. So, How can i connect DMA with microblaze ? However: I have no idea at all on how to achieve this DMA data transfer via AXI4 to the microblaze working memory. Any Example design also help me. If anyone has, please share to me. I need to connect DMA with microblaze.
  13. Hello, I am following this tutorial for microblaze for the nexys 4 ddr: I am getting an error for the mig_7_series... generation that is outlined when I try to generate the bitstream in step 14. It looks like it is pulling the mig from Xilinx's core generation, is it supposed to be using the mig from the nexys 4 ddr files instead? Here is my error output: Another thing to note, I have a space in the directory path, is that the issue possibly? It is not complaining about anything else though. I have also verified that the file it "can't find" is actually there and has contents. I'm running Vivado 2017.4 WebPack, but I can't imagine this would cause issues for a Xilinx IP core, maybe for IP cores from Digilent.

  14. Hey everyone! I'm new to the forum (and fairly new to VHDL as well), and I was hoping you could help me with a problem. I have a project that I'm working on in Vivado (currently it's just some of the inner-workings of a CPU in development), and I'm trying to implement a container that helps me test the design on my FPGA board (Spartan 7 on a Digilent Arty-S7). The top-level module routes the clock input and reset button input on the FPGA in to the design (inverting the reset button input from active-low to active-high in the process), and routes a 4-bit vector out from the design to 4 LEDs on the board. The purpose is to monitor the high nibble of a 32-bit ALU calculation using the LEDs on the Arty board. The design works under behavioral simulation, and it elaborates correctly (see attached schematic of the elaborated design). However, when I synthesize the design, it is reduced to almost nothing -- with the clock and reset pins routed nowhere, and the LED pins routed to some buffers connected to ground. The entire internals of the design are removed (see included schematic of the synthesized design). Can anyone help me figure out why this is happening? Here are the sources of the upper levels of the design, and the relevant constraints that I've applied for the FPGA board: SOURCES: ---------------- -- pindelivery.vhd -- Routes package pins to logical units library IEEE; use IEEE.std_logic_1164.all; use IEEE.numeric_std.all; use work.cpu1_globals_1.all; entity pindelivery is Port ( clk_in : in STD_LOGIC; rst_in : in STD_LOGIC; leds_out : out STD_LOGIC_VECTOR (3 downto 0)); end pindelivery; architecture behavioral of pindelivery is component topLevel_debug port (clk : in std_logic; rst : in std_logic; led_out : out std_logic_vector(3 downto 0)); end component; signal rst_out : std_logic := '0'; begin rst_out <= not rst_in; tld1 : topLevel_debug port map (clk => clk_in, rst => rst_out, led_out => leds_out); end behavioral; ---------------- -- topLevel_debug.vhd -- Top-level module for debug library IEEE; use IEEE.std_logic_1164.all; use IEEE.numeric_std.all; use work.cpu1_globals_1.all; entity topLevel_debug is port ( clk : in std_logic; rst : in std_logic; led_out : out std_logic_vector (3 downto 0)); end topLevel_debug; architecture behavioral of topLevel_debug is component controlTest port (clk : in std_logic; rst : in std_logic; r0_highnibble : out std_logic_vector(3 downto 0)); end component; begin cpu1 : controlTest port map (clk => clk, rst => rst, r0_highnibble => led_out); end behavioral; ---------------- CONSTRAINTS: ---------------- ## Clock signal set_property -dict { PACKAGE_PIN F14 IOSTANDARD LVCMOS33 } [get_ports { clk_in }]; #IO_L13P_T2_MRCC_15 Sch=uclk create_clock -add -name sys_clk_pin -period 83.333 -waveform {0 41.667} [get_ports { clk_in }]; ## LEDs set_property -dict { PACKAGE_PIN E18 IOSTANDARD LVCMOS33 } [get_ports { leds_out[0] }]; #IO_L16N_T2_A27_15 Sch=led[2] set_property -dict { PACKAGE_PIN F13 IOSTANDARD LVCMOS33 } [get_ports { leds_out[1] }]; #IO_L17P_T2_A26_15 Sch=led[3] set_property -dict { PACKAGE_PIN E13 IOSTANDARD LVCMOS33 } [get_ports { leds_out[2] }]; #IO_L17N_T2_A25_15 Sch=led[4] set_property -dict { PACKAGE_PIN H15 IOSTANDARD LVCMOS33 } [get_ports { leds_out[3] }]; #IO_L18P_T2_A24_15 Sch=led[5] ## Reset button set_property -dict { PACKAGE_PIN C18 IOSTANDARD LVCMOS33 } [get_ports { rst_in }]; #IO_L11N_T1_SRCC_15 ## Configuration options, can be used for all designs set_property BITSTREAM.CONFIG.CONFIGRATE 50 [current_design] set_property CONFIG_VOLTAGE 3.3 [current_design] set_property CFGBVS VCCO [current_design] set_property BITSTREAM.CONFIG.SPI_BUSWIDTH 4 [current_design] set_property CONFIG_MODE SPIx4 [current_design] set_property INTERNAL_VREF 0.675 [get_iobanks 34] ---------------- Any assistance would be much appreciated!

  15. PMODGPIO build on Zybo (2016.4)

    I am attempting to build upon the hdmi demo, here is what I want to accomplish: Take over PMOD_C port as a general purpose digital output (8 pins) Here is what I have done (aside from debugging for hours) I dropped down and wired a PmodGPIO_0 block in my design and connected it to PMOD_C (JC), used the auto-connection automation function in Vivado. The build seems to work just fine, exported hardware, etc as normal. In SDK I get a drivers/ directory in hw_patform_1 with PmodGPIO_v1_0 and everything looks fine. Here are the exact steps I followed from here to where I am now: copied PmodGPIO.h down to hdmi/src (build project directory) copied code (functions) from PmodGPIO.c into video_demo.c (build main .c) copied code (init, main, close) from output_demo.c into appropriate places in video_demo.c Question 1) The code would not execute, because it appears the XPAR_ for PMODGPIO does not feed correctly into xparameters.h. Is this normal? I tried to workaround by checking system.hdf and found the base address for my PMODGPIO 0x40000000 and hard-coded it. This would allow the code to compile, but it does not run correctly, it hangs in GPIO_begin on the statement Xil_Out32(InstancePtr->GPIO_addr+4, bitmap);. This is the first statement where it attempts to write to the mapped memory. I have a feeling that something with the PmodGPIO IP is not building correctly for me, but I don't know how to correct it. I have tried several times to clean and rebuild the project, but again I don't know if I am taking the right steps. Question 2) Is there some type of 'build' that I need to do in SDK or somewhere else to initialize the IP correctly and be able to write to the PmodGPIO ? Thanks!
  16. Hi, I am attempting to read a single-ended analog signal on one of ports A0 through A5 using the XADC in the Arty, but I am unable to connect the proper pins in a Vivado block diagram. Either the bitstream fails, or the C code never reads anything. I have a microblaze design that uses the AXI4 interface to the ADC, but still drives the temperature in the MIG and I followed one person's set-up of the XADC mentioned here, in order to still drive the temperature for the MIG7. I used this guide to do it: I have read everything I could on the matter in the Arty reference manual, but it doesn't mention how to tie these pins in Vivado in the block diagram: Some things I have tried: I have enabled the Channel Sequencer in the XADC wizard and checked likely channels (like Vaux0, etc.). Doing a 'make external' on these new ports always fails implementation with issues related to improper IOSTANDARD on the bank of ports Manually hooking up the input pins by creating ports, hooking them to the XADC ports (like Vaux0), and using XDC constraints fail to implement with similar errors If I don't do 'make external' on any ports but the Vp_Vn one, then the bitstream generates, but the C code does not read any auxiliary channels. I have properly enabled all of them in the code and I loop through every channel to see what it registers. Temperature shows up just fine Is there a way to properly read the analog pins A0-A5 through the Vivado block diagram? Thanks!
  17. Vivado HLS

    Hi, Do you have any experience of using Vivado High Level Synthesis, HLS? Today I use VHDL and C/C++ in microblaze. I am interested in testing HLS but don't know if it is worth spending time on that. Is it easy to get things running using HLS? What are the main pro/cons using HLS instead of VHDL/Verilog? Are the tools mature? Best regards
  18. Arty-Z7-20 board

    Hello, i have since a few days a new arty-z-20 board and i like to learn from the rare examples for that board. I found one example which seems to be the base for Linux (Arty-Z7-20-linux_bd-master). This example was made with the Vivado 2016.4 Suite, but i use the current Vivado Suite (2017.3). In that example are two ip`s that could not be upgraded, because they no longer exists in the current Vivado Suite. Where can i get some working examples with Vivado 2017.3 and higher Support for my new Arty-Z7-20 board? My first Arty board was the Artix-7 "original" board. I had found all the examples that i needed to learn from the beginning to the full scale microblaze architecture. I made good experiences, but now i'am not happy with that arty-Z7-20 board! How do i build the simplest Zynq architecture with UART and "bare metal" OS? How do i build the very easiest Linux architecture and what ip's do i need for that? I have a lot more questions... Thank you...

    Hello everyone, I use 1 pin of the pmod connector of the basys3 board for receiving a signal. So in the .xdc file i set every right but I need to say that the incoming signal is not a clock. In the help it suggests "set_property CLOCK_DEDICATED_ROUTE value [get_nets net_name]". I changed the net_name with the signal name "set_property CLOCK_DEDICATED_ROUTE value [get_nets echo_pin]" but u get this critical warning "Invalid option 'FALSEecho_pin' specified for'objects'. anyone an idee? thank you
  20. Hi, I am trying to learn verilog and digital design using basys3 and vivado (webpack) tools. I implemented a jk flip flop using the following logic: module jk_flip_flop ( input [1:0] sw, input clk, input btnC, output reg [0:0] led); always @ (posedge clk) begin if (btnC == 1) led[0] = 0; else begin if (sw[0] == 1) begin if (sw[1] == 1) led[0] <= ~led[0]; else led[0] <= 1; end else begin if (sw[1]) led[0] <= 0; end end end endmodule What I see is when sw[0] and sw[1] are both 1 and if the previous led state was 1, the led does not turn off completely (it just gets dimmer). What could be the problem here, and how would I go about fixing it? I also tried using other LEDs on the board and each had the same problem. Thanks.
  21. Creating a 25 Mhz clock on the Basys 3

    Hello Forum , Its my first Post so I hope it helps everyone I have this code for generating a 25 Mhz clock having a 50 Mhz clock as main using the basys3 board. I use the LSB as the clock because it will goes 1/2 of the main clock of 50Mhz *//////////////////////* START OF CODE //Clock module clkdiv( input wire mclk , input wire clr , output wire clk25 ); reg [24:0] q; always @(posedge mclk or posedge clr) begin if(clr == 1) q <= 0; else q <= q+1; end assign clk25 = q[0]; endmodule *////////////////////////* END OF CODE So whenever I want to call it I just make a instance of this class. In Vivado, when I open my synthesized project and click [Tools ---> Edit devices properties] This is where I select my clock frequency as 50 MHZ { Please see image attached } So my questions are : Is this the proper way to set up a clock using Vivado and the Basys3 Board?In the main page of the Basys3 it says that one can get a clock as high as 450 Mhz but in the options of the [Tools ---> Edit devices properties] I can only find clocks as high as 66 MhzAnd just some basic ones Why Vivado takes sooo long to synthesized, implement and generate the bitstream of an easy and small code? Just implementing in hardware an AND gate takes me 5 minnutes to download the program to the board. Is there a quicker way ? Thanks Forum .
  22. Hello, I have a Nexys 4 DDR board and I was going through the tutorial. I installed the suite and when I reach the point to connect the target, Vivado is unable to find it. The jumper of the JTAG is right and I tried more than one USB cable. The error I get on Vivado is "No hardware targets exist on the server [TCP:localhost:3121]" Your help is appreciated. Ahmed
  23. are there any tutorials for dummies on getting a zybo board to produce a tone? one that thoroughly explains its steps?
  24. Arty hello world

    Hello to all, I'm a college student with a bit of arduino experience. I got ARTY because I have a course that requires learning the VHDL rudiments. (the choice of board was free, I hope I made a good choice!) My goal would be to start with a very simple project, maybe turn on some LEDs by pushing the buttons and getting familiar with the development environment. I am currently using Vivado 2017 and I have managed to have arty in the project board list. After that I do not know what to do, and I did not find a giuide for dummies that explained how to get to my goal. I have to use VHDL and for now my goal is to have a code as clean as possible and essential (also at the expense of not using all the potential of the board) I hope it is a not too complex and accessible request happy to start
  25. This issue had been a pain ever since I started using the CMDO-A7 devices. In Windows 7, using Vivado 2016.2, if I open the hardware manager in Vivado to configure the device, after a few minutes Vivado decides that the target is no longer available and disconnects it. This is a particular problem when I am also using the USB UART... though the problem doesn't happen immediately. This issue makes using the ILA extremely difficult to impossible with this board. When I use the Adept Utility for Windows to configure the board I can use the UART all day without a problem. I suspect a JTAG/UART driver related issue is to blame.
