  1. Greetings, Just bought the Nexys A7-100T was using Nexys 2 up until now. Currently using ISE 14.7 looking for the User Constraints file for this board in the resource page nowhere to be found. There is in the examples a .xcf file which does not help me at all. Tried to type in a simple .ucf file no luck there example below. Tried to use the .xcf file that does not work. Renamed the .xcf file to .ucf file that does not work. NexysA7.ucf Frustrated with new board cannot even get it to make a simple Adder. I receive the following error when generating the bit file. I have included my source a simple Full_Adder instantiated from the system entity in system.vhdl file. Started : "Generate Programming File". Running bitgen... Command Line: bitgen -intstyle ise -f System.ut System.ncd ERROR:Bitgen:342 - This design contains pins which have locations (LOC) that are not user-assigned or I/O Standards (IOSTANDARD) that are not user-assigned. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To prevent this error, it is highly suggested to specify all pin locations and I/O standards to avoid potential contention or conflicts and allow proper bitstream creation. To demote this error to a warning and allow bitstream creation with unspecified I/O location or standards, you may apply the following bitgen switch: -g UnconstrainedPins:Allow INFO:Bitgen:40 - Replacing "Auto" with "NoWait" for option "Match_cycle". Most commonly, bitgen has determined and will use a specific value instead of the generic command-line value of "Auto". Alternately, this message appears if the same option is specified multiple times on the command-line. In this case, the option listed last will be used. ERROR:Bitgen:157 - Bitgen will terminate because of the above errors. Process "Generate Programming File" failed System.vhd Multiplier.vhd
  2. Hi, I am trying to establish a lowpass filter to Audio Demo code of Nexys A7 board. I have implemented a filter however i hear just a noise. If you share your time, i will be happy. I have added the project which was generated by Vivado 2018.2. Vivado Project Best regards.
  3. Hello, I am using the Nexys A7-100T board.And I'm able to successfully read external input voltages on XADC Demo provided in the " ". I want to measure external input voltage(taken from measurement system) and show the parameter on PC. Now I try to modify the XADC Demo program,but I am still a beginner so I can't succeed. Please let me know how to do for making program. thanks marimo
  4. Hi Everyone, I am trying to make my own OrCAD schematic by referencing the evaluation board schematic. The components D1, D3, D5, D7, D9 are missing their manufacture part number. I have used the microscrope to see on top of this chip is says 6H Z on it, but I cannot find any order information online. Please help if anyone knows what that part is it. Thank you.
