  1. Since you folks an Digilent make these wonderful board files that make it super easy to connect components, I figured I'd make my own for a custom board. The problem is that my design uses a differential sysclock, whereas most Digilent designs use a single-ended sysclock. I have been pouring over the board file chapter in UG895 to figure out how to do this, but unfortunately I haven't found any examples or hints in doing so. A single-ended clock interface in the board.xml file looks like this: <interface mode="slave" name="sys_clock" type="xilinx.com:signal:clock_rtl:1.0" of_component="sys_clock" preset_proc="sys_diff_clock_preset"> <description>3.3V Single-Ended 100MHz oscillator used as system clock on the board</description> <port_maps> <port_map logical_port="clk" physical_port="clk" dir="in"> <pin_maps> <pin_map port_index="0" component_pin="clk"/> </pin_maps> </port_map> </port_maps> <parameters> <parameter name="frequency" value="100000000" /> </parameters> </interface> Which allows one to click and drag "System Clock" from the board tab into the block design and gives you a clocking wizard with a single-ended clock. I want to be able to do the exact same thing, except instead of spawning a clocking wizard with a single-ended clock, it spawns a clocking wizard with a differential clock, like this: Here is my failed attempt at creating this interface: I used "xilinx.com:signal:diff_clock_rtl:1.0" instead of "xilinx.com:signal:clock_rtl:1.0" and added another port map for the p/n signals. <interface mode="slave" name="sys_clock" type="xilinx.com:signal:diff_clock_rtl:1.0" of_component="sys_clock" preset_proc="sys_diff_clock_preset"> <description>3.3V Double-Ended 100MHz oscillator used as system clock on the board that don't work none good</description> <port_maps> <port_map logical_port="CLK_P" physical_port="clk_p" dir="in"> <pin_maps> <pin_map port_index="0" component_pin="clk_p"/> </pin_maps> </port_map> <port_map logical_port="CLK_N" physical_port="clk_n" dir="in"> <pin_maps> <pin_map port_index="0" component_pin="clk_n"/> </pin_maps> </port_map> </port_maps> <parameters> <parameter name="frequency" value="100000000" /> </parameters> </interface> and I added the following pins to my pin file: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <part_info part_name="xc7a200tffg1156-2"> <pins> <pin index="00" name ="clk_p" iostandard="LVCMOS25" loc="AG29" /> <pin index="01" name ="clk_n" iostandard="LVCMOS25" loc="AG30" /> Which gives me this message: "'System Clock' board component cannot be connected because no possible options to connect." when I try to click and drag system clock into the design: Do I need to edit the preset file, or is the syntax for my interface definition incorrect, or am I missing something else entirely? Any help is greatly appreciated. Thanks in advance
  2. We are suppose to add a library from here: https://github.com/Digilent/vivado-library/releases and add it to the projects IP repository list to be able to add the block in the IP Integrator. I have checked all the releases and i cant find the Pmod NIC100 anywhere, i think its called PmodNIC, but correct me if am wrong because i haven't seen it anywhere anyway. Until i find this IP, the Pmod is just another paperweight on my desk along with my stalled project, Please help. I am using the Arty A7: Artix-7 FPGA Development Board.
  3. Hello, I use the internal circuit board of Analog Discovery 2 on my test fixture board but the external case is not used. Would you please provide a 3D model of the internal circuit board assembly (PCBA)? Thanks, Choon Shin

    PikeOS project on ZC702

    Greetings all, I'm facing some issues in running my PikeOS project on zc702 board Following are some brief steps that i took to make PikeOS's project i selected a pikeOS integrated project, using devel-apex demo template Board Parameters Description: Xilinx Zynq-7000 All Programmable SoC ZC702 Evaluation kit. Architecture: arm Processor: v7hf Boot Strategy: uboot_dtb then in project Configuration, set path of binery to run on partition. on boot, it generate a file name, apex-devel-zynq-zc702-uboot in order to boot this project on board using sd card few more files are required. This is where i'm lost, can't figure how to generate those files, or where to find then. Hopefully Someone can help me. Thank You.
  6. 1.What is the exact difference between the board and the platform? 2.Are there usable platforms without SoC or any processor on them? 3. How can be the boards connected to each other?

    missing Zybo SD card definition

    Hello to all, While considering to use SD card socket integrated into the Zybo board I've noticed that its definition (package constraints) was not included into the board files. I guess that I can try to add it by myself or ask Digilent to be kind and add it. Unfortunately, I am not familiar with the software used to generate the XML file. Perhaps it can be done in Vivado? Please, advise me on that. Thank you!

    Arty board power..

    Hello, I’ve just got my new Arty board, the LED demo runs, I plugged a JTAG cable into it and took a look at the hardware via Vivado.. (JTAG cable is a Digilent HS1 RevA).. I’m powering the Arty board over USB. I’m seeing 4 reference voltages at 0V (as per picture), is that normal? The power LED is red (LED11) is that normal, I ask because is coloured green on the user manual. Many Thanks Gra

    Arty Board Definition incorrect

    I can confirm the problem with the Arty board definition being incorrect. I posted about this over at Avnet but there has been no response. I bought my board from them. I am attaching the ZIP file that I loaded into Vivado per the instructions. This is a pain because it's hard to get a MicroBlaze design going with an error like that. Any help is appreciated.

  10. Hello. The electronics explorer is a wonderful instrument, no doubt, but there's something that needs to be adressed. I would say "the documentation is awful", but it would be a blatant lie, because there is no documentation (Forgive my cheekiness). For the last few days I´ve been learning how to use it by trial and error, looking at the 3 examples present on the website and figuring out more or less what's going on. There is no quick start guide, no reference manual and the closest to any documentation on how to use the board comes from the RealAnalog videos in which the board is used but some of us have no time to see. It would be great to have a decent-sized pdf with all the necessary information so some of us can munch it up in a couple of hours and power up the beast straight away to whatever proyects or assignments we're up to! Again, forgive my cheekiness and I hope this helps build a better and more consumer ready product.

    Sawtooth waveform

    Hello I got an explorer board this week, great product, however I came across a problem today, or maybe its just me being unable to find it, but the waveform generator does not have a sawtooth preset, all I can see is a triangular waveform. Is there something i'm missing? Thank you
  12. Hello. I am interested in purchasing the electronics explorer board, however after a not-so-quick google about the board I was unable to find any information about the protection the board offers. I am interested in knowing whether the board has any protection against accidental short-circuits, particularly the waveform generator since I read that waveform generators are particularly succeptible to getting damaged when short circuited, but also the rest of the components of the board. Thanks in advance I´ll be waiting for your answers
