  1. @[email protected] sir, Actually i want to implement IFFT of signal to reconstruct the original signal from Frequency domain to time-domain. For this purpose, I've taken sine wave as reference and implemented FFT to get the frequency of orignal signal. Square and sum is taken for getting amplitude of signal only. Now looping-back the signal from FFT block (Frequency domain) to IFFT (time-domain) to re-construct the original signal. Results show that there is major mistake in my concept that I am not achieving the waveform. So i need help regarding IFFT implementation of a signal.
  2. Hello, I want to access analogue pin of XADC header to input audio data in FPGA (Virtex VC707 here). But i am getting error in writing bit-stream "Partially routed nets". Design is below: As we provide the pin number and voltage standard in constraint file for pin assignment, but here the I/O Std is faded and cannot be edited. I have also edited constraint file manually but still getting this error. Pin assignment are as under for VC707 Schematics diagram for VC707 Any help will be appreciated. Thanks,
  3. Sir i have already split this into parts. The first waveform titled "Sine" is the output of dds_compiler_0, second waveform is the output of FFT block and finally third one is the output of IFFT block.
  4. Hello sir, I have implemented FFT of sine wave using "FFT IP core". It gives me exact frequency of the input. But when i tried to implement IFFT of that output using "FFT IP core with configuration value 8000H", output is not again sine wave in time domain. Could you please help me to sort this out? Thanks and regards
