  1. I recently got a Nexys 4 DDR and I'm trying to get started with a simple switch/blink-LED program. I'm using ISE Design Suite 14.5 (nt64) and I'm getting warning messages that's preventing the design from completely compiling. This is what I tried: Created a very simple design (in schematic mode) using three switch inputs, an LED output, and basic logic (AND & NAND)Added 3 ibuf, one for each input and an obuf for the outputAssigned each ibuf/obuf pin numbers from reference manual (e.g. LOC = J15)Added I/O markers, labeled A, B, C (inputs), and F (output)Get the following warning messages during compile (Implement Design > Map)WARNING:LIT:701 - PAD symbol "A" has an undefined IOSTANDARD.WARNING:LIT:702 - PAD symbol "A" is not constrained (LOC) to a specific locationThus, I'm unable to generate a Programming File (bit file?)What am I doing wrong? Am I missing a step? This was pretty much the same procedure I followed when I worked with the first-gen Basys board, using an older version of ISE (9.2), and I was able to do much more complex designs with no problems. From what I understand, I would create a design in ISE 14.5, compile it using Synthesize-XST, Implement Design, and Generate Programming File (bit file?). Then I would send the bit file to the Nexys 4 DDR using Digilent Adept? Should I start using the Vivado Design Suite? I heard it's like $2000+ for a license. I also heard there's a device-limited license?

    newbie questions

    I bought a basys3 and a nexys4 ddr 1.) I tried to use web pack vivado, but when i simulate or build bitstream files(.bin or .bit) i get error no license. so i downloaded xilinx ise. 2.) with ise i can produce bit and bin files, but how do you get them to the device. I guess i could put them on a micro sd card and use the jumper.....but that does not transfer them to the non-volatile flash right? How can i transfer them to non-volatile flash? Thanks in advance Eddie

    Vmod+nexys 4

    Hi all, I am a 4th year engineering student from RMIT university of Australia. I'm in the search for FPGA board for the purpose of generating a depth map via stereo cameras, as part of a larger project. What has caught my eye is the Nexys4-DDR board primarily for its Xilinx Artix-7 chip and upon further searching the Digilent store i so found the VmodCAM module which may be particularly useful for the project. However i am aware as to the fact that the Nexys4 board does not have a VHDCI port and hence would like to know of any work arounds to this issue, possible PMOD cameras or other ways to connect a pair of cameras to the Nexys 4 board. Thank you for your time and assistance.
  4. This question was posted by Daedronus on the Nexys4DDR youtube video: Artix 7 can output directly hdmi video, why bother wasting IOs for the rather poor 12bit vga?
