  1. Hello, I'm building this filter, generating a .COE file in Matlab, which I use in the FIR compiler IP. Here are two screenshots of the settings. Do you know if the difference between the two pictures, in terms of magnitude, are just a displaying fact or if there is a real amlpification involved by the FIR compiler ? If it's the case, do you know how to fix it to generate the same filter as I designed in Matlab, so without gain ? Kind regards, Yannick
  2. I am facing problem in how to use XADC wizard in Nexys 4 DDR board I just want to get the digital conversion of external inputs and access that 12bits of digital output directly. I am new to this and for now, I'm trying to just interlink XADC and a 12bits of DAC to convert an analog input(taken from a function generator) to digital(which will be stored in FPGA) and then use that digital data to generate the same signal at the output of a DAC. It will be really helpful If you can explain/provide a step by step process to do it. You can help using block design or a source code.... whichever way possible.
  3. Hi Digilent, My Nexys 4 DDR couldn't be powered on and I found that the IC20 on board was disappered. However, I can't find this chip in the schematic. Could you let me know this IC's type and I will buy it to repair board myself. Thanks
  4. 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
