+--* Using g_fft_guard_w = 2 for the first stage does not decrease the processing gain when g_fft_stage_dat_w ~=> 22. However
+-- when g_fil_backoff_w = 1 then it is not necessary to use g_fft_guard_w > 1, because then the input to the FFT is already
+-- scaled down by the factor 2 of g_fil_backoff_w = 1.

+--Conclusion:
+--* If g_fft_stage_dat_w is large enough (~=> 24), then using extra_w has no benefit (as expected)
+--* Combination of using both g_r2_mul_extra_w and g_sepa_extra_w has most benefit, for
+-- g_fft_stage_dat_w ~=> 22 it is sufficient to use 1, 1.
+--* Using g_fft_stage_dat_w = 22 with extra_w 1, 1 yields 19.59 [dB],
+-- using g_fft_stage_dat_w = 24 with extra_w 0, 0 yields 20.08 [dB] so ~= 0.49 dB better
+-- using g_fft_stage_dat_w = 24 with extra_w 1, 1 yields 20.31 [dB] so ~= 0.72 dB better, but with 2, 2 it is even slightly less.

+-- Purpose: Test bench to investigate quantization in poly phase filterbank (PFB) using WG. The main goal is to
+-- verify that the PFB achieves the expected processing gain between input SNR and subband output SNR.
-- Description:
--- . Use g_sel_pfb to select: APERTIF wpfb_unit_dev.vhd or LOFAR1 pfb2_unit.vhd
--- . This tb assumes two real input and wb_factor = 1 and nof_chan = 0.
+-- . Use g_sel_pfb to select the APERTIF wpfb_unit_dev.vhd or LOFAR1 pfb2_unit.vhd as device under test (DUT).
+-- . This tb assumes two real input and wb_factor = 1 and nof_chan = 0 (as for LOFAR2.0).
-- . The tb measures the signal to noise ratio (SNR) at several stages:
-- - WG output
-- - FIR filter output
-- - SST
-- The SNR is use to determine the performance of the WPFB:
--- - the implementation loss due to quantization should be at least a factor 10 less than the input quantization
+-- - The implementation loss due to quantization should be at least a factor 10 less than the input quantization
-- noise of the ADC. If the noise power increases by a factor 1.1, then the SNR will reduce by 10*log10(1.0/1.1)
-- = 0.4 dB.

+-- - The FFT achieves the processing gain for the WG signal at the specific subband. The subband filterbank has
-- N_sub = N_fft/2 = 512 subbands, so the expected processing gain of the FFT (for a real input) is
-- 20*log10(sqrt(N_sub) = 27.1 dB.
-- - The expected SNR of a subband in the SST is processing gain - implementation loss = 27.1 - 0.4 = 26.7 dB
-- higher than the SNR of the WG input signal.
+-- - The polyphase FIR filter of the PFB uses the same Coeffs16384Kaiser-quant.dat coefficients as in LOFAR1.
+-- From run_pfir_coeff.m it follows that the equivaluent nois bandwidth of a subband with this filter is
+-- 0.96 bins, so for the PFB the expected processing gain increases by about 10*log10(0.96) = 0.17 dB compared
+-- to for the FFT, so about 27.3 dB.
-- . The WG does not produce a perfect sampled sine. Therefore the SNR of the WG input will be somewhat
--- less than the theoretical SNR of an ADC (SNR = W_adc * 6.02 + 1.76 dB).
+-- less than the theoretical SNR of an ADC (SNR = W_adc * 6.02 + 1.76 dB). Hence for W_adc = 14 the SNR of
+-- the generated carrier wave (CW) sine is SNR = c_wg_snr_a_dB = 86 dB.
+-- . For fractional WG frequencies for which the period does not fit the WG internal buffer size of
+-- g_buf_addr_w, the SNR of the carrier wave (CW) is limited to SNR = (g_buf_addr_w-1) * 6.02 + 1.76 dB
+-- (see diag_wg.vhd). The g_buf_addr_w = 10. Therefore for fractional g_subband_index_a,b the effective SNR
+-- of the generated CW sine is SNR ~= 56 dB, even when W_adc = 14 > 9 bit.
-- . The SNR of the WG and the FIR filter output is measured by estimating first the amplitude and
-- phase of the input sine. These estimated amplitude and phase are then used to create a local CW
-- (carrier wave) and subtract that from the input sine to get the equivalent noise. The SNR is then

-- . The SNR of the SST is measured by using the power in the subband that corresponds to the WG
-- frequency as signal power, and the power in the other subbands as noise power.

+-- . The tb does support using and using WG frequencies that fall fractionally between subbands, provided that
-- the fraction is a multiple of 1/c_N_blk, because then the WG sine will have DC = 0 over the sync interval
-- of c_N_blk blocks.
--- . The FIR output SNR cannot be measured for fractional WG frequencies, because then the FIR filter output is
--- discontinuous after every block of c_N_fft samples, due to that it is a polyphase FIR filter. This makes that
--- the amplitude and phase of the FIR filter output cannot be determined, so then the FIR filter output noise
--- estimate is also not valid. Therefore FIR output SNR estimation and logging is disabled when fractional
--- subband frequencies are used.
-- . For the SNR measurements it is sufficient to use WG frequencies at the subband center.
--
+-- Remark:
+-- . In retrospect it would have been better to use quantized REAL SIN() in testbench as carrier wave (CW)
+-- waveform source, instead of using the WG, because the WG is not good enough for fractional subband
+-- frequencies and because SIN() is easier to use in the test bench.
+-- . Using quantized REAL also allows defining other input signals, like noise or combination of SIN() and
+-- noise, although such tests are better done in MATLAB. Purpose of this tb is only to verify the
+-- implementation losses.
+-- . The WG frequency resolution can be improved by using a longer reference waveform in the WG buffer RAM.
+-- Fractional subband frequencies of 0.1 can be supported accurately by using a reference waveform that
+-- has a factor 1/0.1 = 10 more resolution.
