  1. I need to use the JTAG header to program the Zedboard, since the MicroUSB connector is physically damaged. I cannot find any documentation or forums about how to use the JTAG connector for programming the FPGA, so I am going to ask for your help. I have a basic design in Vivado for making switch 0 toggle led 0. The bitstream is ready to be sent to the FPGA. However, when I try to connect to the hardware, by clicking "Open target", it is unable to connect. When I try to manually connect: I am using Xilinx Platform Cable USB adapter for connecting the JTAG to the computer's USB input: I have the driver installed, and it appears in my list of devices when plugged in, and disappears if I unplug it, and is up-to-date: I suspect the jumpers may not be configured properly? But again I cannot find clear documentation on how to set this up. This is how mine is set up: Here is some information about my computer: I am using Vivado 2016.1, since that is used in a lot of the tutorials. I think the Diligent tutorial uses 2016.2. It also comes with the Zedboard board file, although I downloaded the one made by Diligent as instructed in the tutorial. I hope I have provided enough information. I appreciate any help!
  2. Hello everyone, So I own a Basys 2 board with spartan 3E FPGA and I am using ISE Design Suite 14.5. I want to create a VGA output with 800x600 resolution and 40Mhz clock so it will have 60Hz refresh rate. I am writing the code in verilog. I have entered exact numbers for horizontal counter, vertical counter, hsync and vsync that are required for operation stated above. However, I am unable to output the VGA signal. I am using two DCMs that can be generated in the ISE design suite, I am using first DCM to multiply 50MHz clk to 100Mhz and then I am using second DCM to divide 100Mhz with 2.5 to get 40Mhz clk frequency. I tried many combinations of DCM properties (like setting external clkin and internal, changing feedback properties etc.) but was not successful. I am uploading the whole code directory archived in a Winrar, so you can also maybe replicate the issue. Any help is appreciated! Thanks in advance. lab9v360hz.rar
  3. I am working in an DSP algorithm, I have generated the bitstream for that algorithm and dumped into FPGA basys 3 board (the output of the algorithm is of 16-bit wide and consists of 100 samples). Now, I need to view the waveform with the help of Waveforms software and analog discovery kit. So, how it can be done? Can anybody provide me some video or anyother material that can solve the problem. #So far information obtained# In the material "Basys 3™ FPGA Board Reference Manual Overview" page no. 18, since, my data is of 16-bit wide I have connected pmod pins JB1 to JB4 to analog discovery pins 0 to 3 and JB7 to JB10 to analog discovery pins 4 to 7 to transfer first 8-bit. Similarly, JC1 to JC4 and JC7 to JC10 are connected to the 8 to 11 and 12 to 15 no pins of analog discovery. Is the connection is ok? What will be other connections needed?
