-- Author: R. van der Walle (original), E. Kooistra (updates)
-- Purpose: Self-checking testbench for simulating lofar2_unb2c_sdp_station_bf using WG data.
-- Purpose: Self-checking testbench for simulating lofar2_unb2c_sdp_station_bf
-- using WG data.
--
-- Description:
-- This tb is a balance between verification coverage and keeping it simple:
-- - Use only one signal input (g_sp), put small unused signal on the other
-- signal inputs.
-- - Use different BF weight for the two beamlet polarizations (g_bf_*_gain,
-- and g_bf_*_phase) of signal input g_sp. Keep BF weight for the other
-- signal inputs = 0 to block them from the beamlet.
-- - Select one beamlet for the subband (g_beamlet).
-- - Use same stimuli for both beamsets.
--
-- MM control actions:
--
-- 1) Enable calc mode for WG on signal input g_sp via reg_diag_wg with:
-- g_subband = 102 --> WG freq = 19.921875MHz
-- g_ampl = 1.0 --> WG ampl = 2**13
-- 1) Enable calc mode for WG on signal input (si) g_sp via reg_diag_wg with:
-- g_subband = 102 --> 102 * f_sub = 19.921875 MHz
-- g_wg_ampl = 1.0 --> 1.0 yield WG ampl = 2**13
-- g_wg_phase --> subband phase
-- Use g_unused_ampl = 0.1 and g_unused_phase = 0.0 for the other signal
-- inputs, that are not used in the BF.
--
-- 2) Read current BSN from reg_bsn_scheduler_wg and write
-- reg_bsn_scheduler_wg to trigger start of WG at BSN.
--
-- 3) Read and verify subband statistics (SST) for g_sp. This also reads the
-- SST of the other signal input of the WPFB that processes g_sp.
--
-- 2) Read current BSN from reg_bsn_scheduler_wg and write reg_bsn_scheduler_wg
-- to trigger start of WG at BSN.
-- 4) Select subband g_subband for beamlets in g_beamlet
--
-- 3) Read and verify subband statistics (SST)
-- 5) Apply BF weight to g_beamlet X beam and Y beam, so for example if g_sp
-- = 3, then w_x3 = g_bf_x_gain/phase and w_y3 = = g_bf_x_gain/phase. The
-- other BF weights are 0.
--
-- 4) Select subband g_subband for beamlet g_beamlet
-- WG BF BF
-- si weight weight
