    Beginner DSP Projects

    Hey all I've just recently got my Nexys 4 DDR Board. I am looking for some intro DSP projects to do on my FPGA. I took a DSP course last year but it was pretty much only theory. So I know the theory very well, but am not sure what is a good project to start out in DSP? Any suggestions would be appreciated, thank you!

    Vivado - How to reflash HDL code quickly

    Thanks for the info!! I am very interested in FPGAs as I want to make my living using them and related tools, so I will most definitely take a deeper look at stuff like this in the next few months.

    Vivado - How to reflash HDL code quickly

    Thats really surprising. I'm used Altera's tools for the last few years for school and re-flashing code took maybe 30 seconds. Perhaps we had a special kind of setup.

    Vivado - How to reflash HDL code quickly

    Hi everyone I just got my Nexys 4 DDR and I'm trying to get familiarized with XDC files and writing some basic HDL projects. I know how to generate a .bit file and program my FPGA, but I was wondering if there is a quicker way than Synthesizing, Implementing, and then Generating. It takes like 5-6 minutes right now. I'm making little changes to my Verilog source files very often so this re-programming time seems absurd. If I JUST make a change to my .v file, what is the quickest way to reprogram my device?
  5. Hello everyone I am selling my almost brand-new Xilinx Nexys 3 Trainer Board w/ Spartan 6 FPGA. I've only used it for about 1 week and it is in absolute Mint condition. I am choosing to sell it because my new job at a startup uses Altera's line of products so I will be getting an Altera FPGA Unfortunately I just got my Nexys 3 so I am try to get whatever money I can for it. A link to this product on the Digilent site can be found below: https://store.digilentinc.com/nexys-3-spartan-6-fpga-trainer-board-limited-time-see-nexys4-ddr/ As you can see, it's worth $270 on the website, the total comes to over $300 if you order it from the store. I was hoping I could get around $200 if possible but am definitely open to haggling depending on the demand. Please let me know if you are interested! This is a great board to build projects and can do a ton of things! Inbox me or comment here

    Impossible Nexys 3 / Adept 2 Setup - PLEASE HELP!

    @jpeyron Okay thanks for the suggestion. I will try to work through this when I get a chance and let you know what happens. For now I am too excited that I can program my FPGA finally

    Impossible Nexys 3 / Adept 2 Setup - PLEASE HELP!

    I am using the USB-microUSB cable that came in the box with my Nexys 3 board. Btw here's an update: So I am able to generate the bit file using Project Navigator within the ISE Virtual Box Application. I then pass that .bit file back to my win10 host using the shared drive, and can successfully program the FPGA using the Windows Adept application with the GUI. However, I would like to get Adept working in the ISE VBox application just for continuity and organization purposes. I am still not able to find the device using "djtgcfg enum".

    Nexys 3 Getting Started

    I am having the exact same problem as timothyheider. We have the exact same setup with the ISE Tools running in a Virtual Box. After having installed the Adept Utilities + Runtime like you said, I try to run "djtgcfg enum" but get "No devices found" back. I have tried to install the cable drivers using the install_drivers script found within the Xilinx cable driver documentation, but it doesn't seem to have done anything. Please advise...

    Impossible Nexys 3 / Adept 2 Setup - PLEASE HELP!

    Unfortunately, the install_drivers script did not properly install the cable drivers. I suspect it has something to do with windrvr6 not existing on my system. Here is what I see when I run the script as root: And then when I try to check for the devices, as root, I see the same result: Any ideas what to do? From what I've read, getting windrvr6 on the ISE Virtual Box is a very difficult and lengthy process. I'm very surprised by how long the process of setting up this FPGA is taking, but I will try to remain strong Thanks

    Impossible Nexys 3 / Adept 2 Setup - PLEASE HELP!

    Thanks for the tip. I will to manually install the digilent cable drivers on my ISE VirtualBox when I get home and let you know how it goes.
  11. Hi everyone So I've been trying to set up my Nexys 3 (Spartan-6 FPGA) board to do some projects. I'm running a Windows 10 Host, and I've been following this "Getting Started" tutorial: https://reference.digilentinc.com/learn/programmable-logic/tutorials/getting-started-with-fpga/start So I installed the ISE Webpack, which gave me a VirtualBox where I have stuff like ChipScope, EDK, and Project Navigator. I was able to create a new project in the Project Navigator and generate the bit file. Now I am trying to program my board with the bit file using Adept, like the tutorial suggests - AND THIS IS WHERE EVERYTHING GOES WRONG I am trying to get Adept on my ISE VirtualBox. I am following this tutorial: https://techoverflow.net/2012/10/05/how-to-program-nexys3-fpga-board-on-linux-using-digilent-adept-software-a-guide-for-beginners/ I was able to install the Adept2 Runtime and Utilities using their install.sh files that come with the installation. However, when I run "djtgcfg enum" it says "No devices found", and this is where I am completely lost. I have no idea how to get my device recognized through my ISE VirtualBox. Now here's the extremely confusing / disorienting part: 1) Apparently Digilent Adept 2 is ONLY FOR Windows (source: https://store.digilentinc.com/digilent-adept-2-download-only/). 2) Apparently Adept software DOESNT SUPPORT VIRTUALBOX DRIVERS So I am absolutely lost here. Apparently I can't see my Nexys 3 Board from within the ISE VirtualBox. When I plug in my FPGA, on my Win10 host I can see the device in the "Device Manager" as a "Digilent USB Device". So i took the project0.bit I generated with the Project Navigator, passed it to my Windows Host, and ran it with Adept (the windows version) and guess what... the program didnt work lol rip It's supposed to flash some Green LEDs in some sort of a pattern but it seems like my board is just frozen, with the 7-Seg displays being slightly lit. Definitely not what I was expecting. Im not sure what I am doing wrong, or why the ISE VirtualBox is needed at all. There is so much inconsistency on the internet about how to program on this board it is absolutely disorienting, and this "Getting Started" tutorial does not explain absolutely anything. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- TL;DR - I am trying to run a basic program on my Nexys 3 board with Spartan 6 FPGA. I generated a project0_demo.bit using Project Navigator within the ISE VirtualBox but can't see my Nexys 3 board from within the VirtualBox, and can't get Adept on my VirtualBox either. My Nexys 3 is recognized in my Win10 Host as "Digilent USB Device", so I passed the project0_demo.bit back to my Win10 host, and programmed it using Adept and the program did not work as intended. What am I not understanding, and what should I be doing differently?
