Therefore, we wanted to verify the functioning of this project on Pulpino via RTL simulation. However, we encountered some issues, which we want to share with you. Please find the details of the tests below.
T-1. We realized that the fixed-point real-to-imaginary KissFFT function was used in your project. Therefore, we first checked the functioning of the kiss_fftr function on a Linux computer, so we got correct complex results both in 16-bit and 32-bit.
T-2. Then we compiled and ran the ETH Zurich and Uni. Bologna version of KissFFT on a Linux computer, which includes g_fftr_state configuration like "{(kiss_fft_cfg)&g_fft_state, g_fftr_state_tmpbuf, g_fftr_state_super_twiddles}; " instead of "kiss_fftr_alloc(nfft, 0, 0, 0);". We tried this with two input stimuli. In the first trial, we used the stimuli.h file including 512-point 16-bit values. In the second trial, we changed the stimuli to a constant (0x1000) padded with 511 zeros. In both cases, we got wrong results.
T-3. Finally, we ran an RTL simulation of KissFFT on Pulpino platform, with the KissFFT project and the stimuli provided on Github of ETH Zurich and Uni. Bologna. What we got was a single-sided FFT result (257-point freq bins output, resulting from a 512-point real input sequence), which consists of all zeros.
Therefore, here are our questions:
Q-1. Is there anything wrong with the setup of our HDL testbench, or with our usage of your version of KissFFT? (Buna cevap almak için testbench'imizi paylaşman gerekebilir.)
Q-2. Why is a g_fftr_state configuration like "{(kiss_fft_cfg)&g_fft_state, g_fftr_state_tmpbuf, g_fftr_state_super_twiddles};" being used in your Pulpino-oriented project? What is the purpose, and functionality of this augmentation?

we would like to implement the KissFFT project on a Pulpino SoC We realized that, the KissFFT project provided on Github by ETH Zurich and University of Bologna provided the 1-D FFT and results checking functions. More importantly, it was designed for the Pulpino platform.
