LogiCORE Fast Fourier Transform (FFT) v7.0/v7.1/v8.0 - Release Notes/README for Fast Fourier Transform (FFT) v7.0/v7.1/v8.0 C-Model rev1 Patch for LSB mismatches.

Description

This Answer Record contains the Release Notes for the LogiCOREIP Fast Fourier Transform (FFT) v7.0/v7.1/v8.0 C-Model rev1 Patch which deals with the LSB Mismatch outlined in (Xilinx Answer 39011).

Solution

Download the LogiCOREIPFast Fourier Transform (FFT) v7.0/v7.1/v8.0 C-Model rev1 Patch from:

http://www.xilinx.com/txpatches/pub/utilities/fpga/ar39329_fft_c_model_rev1.zip

Extractthe patch by extracting the contents of the ".zip" archive. Use these files in order to do C-modelling of the FFT. Within the zip file there are:

1. xfft_v7_0_bitacc_cmodel_rev1.zip which is the zip file for win32/win64/lin32/lin64 version of the C-model for FFT v7.0
2. xfft_v7_1_bitacc_cmodel_rev1.zip which is the zip file for win32/win64/lin32/lin64 version of the C-model for FFT v7.1
3. xfft_v8_0_bitacc_cmodel_rev1.zip which is the zip file for win32/win64/lin32/lin64 version of the C-model for FFT v8.0

For more information on how to use these files please refer to the UG associated with the zip file.


Patch Fixes

Issue: There is a FFT LSB mismatch between c-model and implementation.

Symptom: mismatch.
