Rewrite CI workflow to use uv for dependency management, whole-repo `ruff check .`, py_compile syntax gate, and merged python-tests job. Add pyproject.toml with ruff config and uv dependency groups.

The old hex files were generated against the previous 32-point single-FFT architecture and caused 2048/2048 mismatches in both strict real-data TBs. Changes: - Regenerate doppler_ref_i/q.hex, fullchain_doppler_ref_i/q.hex, and all downstream golden files (MTI, DC notch, CFAR) via golden_reference.py - Add tb_doppler_realdata (exact-match, ADI CN0566 data) to regression - Add tb_fullchain_realdata (exact-match, decim->Doppler chain) to regression - Both TBs now pass: 2048/2048 bins exact match, MAX_ERROR=0 - Update CI comment: 23 -> 25 testbenches - Fill in STALE_NOTICE.md with regeneration instructions Regression: 25/25 pass, 0 fail, 0 skip. ruff check: 0 errors. --- .github/workflows/ci-tests.yml | 2 +-

The replay _replay_dc_notch() was treating all 32 Doppler bins as a single frame, only zeroing bins at the global edges ({0,1,31} for width=2). The RTL uses dual 16-point sub-frames where each sub-frame has its own DC, so the notch must use bin_within_sf = dbin & 0xF. This fixes test_replay_packets_parseable which was seeing 5 detections instead of the expected 4, due to a spurious hit at (range=2, doppler=15) surviving CFAR. --- 9_Firmware/9_3_GUI/radar_protocol.py | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/9_Firmware/9_3_GUI/radar_protocol.py b/9_Firmware/9_3_GUI/radar_protocol.py index 85a5867..52e4543 100644 --- a/9_Firmware/9_3_GUI/radar_protocol.py +++ b/9_Firmware/9_3_GUI/radar_protocol.py @@ -459,14 +459,20 @@ def _replay_mti(decim_i: np.ndarray, decim_q: np.ndarray, def _replay_dc_notch(doppler_i: np.ndarray, doppler_q: np.ndarray, width: int) -> Tuple[np.ndarray, np.ndarray]: - """Bit-accurate DC notch filter (matches radar_system_top.v inline).""" + """Bit-accurate DC notch filter (matches radar_system_top.v inline). + + Dual sub-frame notch: doppler_bin[4:0] = {sub_frame, bin[3:0]}. + Each 16-bin sub-frame has its own DC at bin 0, so we zero bins + where ``bin_within_sf < width`` or ``bin_within_sf > (15 - width + 1)``. + """ out_i = doppler_i.copy() out_q = doppler_q.copy() if width == 0: return out_i, out_q n_doppler = doppler_i.shape[1] for dbin in range(n_doppler): - if dbin < width or dbin > (n_doppler - 1 - width + 1): + bin_within_sf = dbin & 0xF + if bin_within_sf < width or bin_within_sf > (15 - width + 1): out_i[:, dbin] = 0 out_q[:, dbin] = 0 return out_i, out_q From 96c1f68778146f42fa9eb756587eaa147899f41c Mon Sep 17 00:00:00 2001 From: Serhii Date: Thu, 9 Apr 2026 14:07:37 +0300 Subject: [PATCH 08/57] docs(readme): replace text disclaimer with WIP badge Swap the verbose Alpha disclaimer paragraph for a simple "Features: Work in Progress" badge next to the existing Alpha badge, per review feedback from @JJassonn69.

Restructured to {0xFF, mode[1:0], stream[2:0], 3'b000, threshold[15:0]} = 32 bits exactly. Fixed in both usb_data_interface_ft2232h.v and usb_data_interface.v. Bug 2 (Python): radar_mode extracted at bit 21 but was actually at bit 24 after truncation — always returned 0. Updated shift/mask in parse_status_packet() to match new layout (mode>>22, stream>>19). Bug 3 (STM32): parseFromUSB() minimum size check was 74 bytes but 9 doubles + uint32 + markers = 82 bytes. Buffer overread on last fields when 74-81 bytes passed.

New modules: software_fpga.py, replay.py (ReplayEngine + 3 loaders) Enhanced: WaveformConfig model, extract_targets_from_frame() in processing, ReplayWorker with thread-safe playback controls, dashboard replay UI with transport controls and dual-dispatch FPGA parameter routing. Removed: ReplayConnection (from radar_protocol, hardware, dashboard, tests) — replaced by the unified replay architecture. 150/150 tests pass, ruff clean. --- 9_Firmware/9_3_GUI/radar_dashboard.py | 13 +- 9_Firmware/9_3_GUI/radar_protocol.py | 385 -------------- 9_Firmware/9_3_GUI/test_radar_dashboard.py | 229 +-------- 9_Firmware/9_3_GUI/test_v7.py | 554 +++++++++++++++++++++ 9_Firmware/9_3_GUI/v7/__init__.py | 30 +- 9_Firmware/9_3_GUI/v7/dashboard.py | 301 ++++++++++- 9_Firmware/9_3_GUI/v7/hardware.py | 6 +- 9_Firmware/9_3_GUI/v7/models.py | 56 +++ 9_Firmware/9_3_GUI/v7/processing.py | 100 ++++ 9_Firmware/9_3_GUI/v7/replay.py | 288 +++++++++++ 9_Firmware/9_3_GUI/v7/software_fpga.py | 287 +++++++++++ 9_Firmware/9_3_GUI/v7/workers.py | 217 ++++++-- 12 files changed, 1773 insertions(+), 693 deletions(-) create mode 100644 9_Firmware/9_3_GUI/v7/replay.py create mode 100644 9_Firmware/9_3_GUI/v7/software_fpga.py diff --git a/9_Firmware/9_3_GUI/radar_dashboard.py b/9_Firmware/9_3_GUI/radar_dashboard.py index 7575e63..3d6988c 100644 --- a/9_Firmware/9_3_GUI/radar_dashboard.py +++ b/9_Firmware/9_3_GUI/radar_dashboard.py @@ -43,7 +43,7 @@ from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg # Import protocol layer (no GUI deps) from radar_protocol import ( -

_ReplayController with threading.Event-based play/pause/stop - Reuses v7.ReplayEngine and v7.SoftwareFPGA for all 3 input formats - Dual dispatch routes FPGA control opcodes to SoftwareFPGA during raw IQ replay; non-routable opcodes show user-visible status message - Seek slider with re-emit guard, speed combo, loop checkbox - close() properly releases engine file handles on stop/reload Demo mode: - DemoTarget kinematics scaled to physical range grid (~307m max) - DemoSimulator generates synthetic RadarFrames with Gaussian blobs - Targets table (ttk.Treeview) updates from demo target list Mode exclusion (bidirectional): - Connect stops active demo/replay before starting acquisition - Replay load stops previous controller and demo before loading - Demo start stops active replay; refuses if live-connected - --live/--replay/--demo in mutually exclusive CLI arg group Bug fixes: - seek() now increments past emitted frame to prevent re-emit on resume -

ERROR_POWER_SUPPLY] (9..13). Two critical faults were left out of the gate and fell through to attemptErrorRecovery()'s default log-and-continue branch: - ERROR_TEMPERATURE_HIGH (14): raised by checkSystemHealth() when the hottest of 8 PA thermal sensors exceeds 75 C. Without cutting bias (DAC CLR) and the PA 5V0/5V5/RFPA_VDD rails, the 10 W GaN QPA2962 stages remain biased in an overtemperature state -- a thermal-runaway path in AERIS-10E. - ERROR_WATCHDOG_TIMEOUT (16): indicates the health-check loop has stalled (>60 s since last pass). Transmitter state is unknown; relying on IWDG to reset the MCU re-runs startup and re-energises the PA rails rather than latching the safe state. Fix: extend the critical-error predicate so these two codes also trigger Emergency_Stop().

Cold-start false trip: static uint32_t last_health_check = 0; if (HAL_GetTick() - last_health_check > 60000) { trip; } On the first call, last_health_check == 0, so the subtraction against a seeded-zero sentinel exceeds 60 000 ms as soon as the MCU has been up >60 s -- normal after the ADAR1000 / AD9523 / ADF4382 init sequence -- and the watchdog trips spuriously. 2. Stale timestamp after early returns: last_health_check = HAL_GetTick(); // at END of function Every earlier sub-check (IMU, BMP180, GPS, PA Idq, temperature) has an `if (fault) return current_error;` path that skips the update. After ~60 s of transient faults, the next clean call compares against a long-stale last_health_check and trips. With ERROR_WATCHDOG_TIMEOUT now escalating to Emergency_Stop(), either failure mode would cut the RF rails on a perfectly healthy system. Fix: move the watchdog check to function ENTRY. A dedicated cold-start branch seeds the timestamp on the first call without checking. On every subsequent call, the elapsed delta is captured first and last_health_check is updated BEFORE any sub-check runs, so early returns no longer leave a stale value. 32-bit tick-wrap semantics are preserved because the subtraction remains on uint32_t. Add test_gap3_health_watchdog_cold_start.c covering cold-start, paced main-loop, stall detection, boundary (exactly 60 000 ms), recovery after trip, and 32-bit HAL_GetTick() wrap -- wired into tests/Makefile alongside the existing gap-3 safety tests. --- .../9_1_3_C_Cpp_Code/main.cpp | 30 ++-- 9_Firmware/9_1_Microcontroller/tests/Makefile | 11 +- .../test_gap3_health_watchdog_cold_start.c | 132 ++++++++++++++++++ 3 files changed, 163 insertions(+), 10 deletions(-) create mode 100644 9_Firmware/9_1_Microcontroller/tests/test_gap3_health_watchdog_cold_start.c diff --git a/9_Firmware/9_1_Microcontroller/9_1_3_C_Cpp_Code/main.cpp b/9_Firmware/9_1_Microcontroller/9_1_3_C_Cpp_Code/main.cpp index b8c9392..932f4a0 100644 --- a/9_Firmware/9_1_Microcontroller/9_1_3_C_Cpp_Code/main.cpp +++ b/9_Firmware/9_1_Microcontroller/9_1_3_C_Cpp_Code/main.cpp @@ -631,6 +631,27 @@ static bool system_emergency_state = false; SystemError_t checkSystemHealth(void) { SystemError_t current_error = ERROR_NONE; + // 0.

This creates a constant 256-LSB DC offset between the golden reference and RTL for all 256 ADC values. The bit-accurate model in fpga_model.py already uses the correct RTL formula. This aligns golden_reference.py to match. Verified: all 256 ADC input values now produce zero offset against fpga_model.py. --- 9_Firmware/9_2_FPGA/tb/cosim/real_data/golden_reference.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/9_Firmware/9_2_FPGA/tb/cosim/real_data/golden_reference.py b/9_Firmware/9_2_FPGA/tb/cosim/real_data/golden_reference.py index 9b0ca86..c384fe6 100644 --- a/9_Firmware/9_2_FPGA/tb/cosim/real_data/golden_reference.py +++ b/9_Firmware/9_2_FPGA/tb/cosim/real_data/golden_reference.py @@ -292,7 +292,7 @@ def run_ddc(adc_samples): # adc_signed_w = {1'b0, adc_data, 9'b0} - {1'b0, 8'hFF, 9'b0}/2 # Simplified: center around zero, scale to 18-bit adc_val = int(adc_samples[n]) - adc_signed = (adc_val - 128) << 9 # Approximate RTL sign conversion to 18-bit + adc_signed = (adc_val << 9) - 0xFF00 # Exact RTL: {1'b0,adc,9'b0} - {1'b0,8'hFF,9'b0}/2 adc_signed = saturate(adc_signed, 18) # NCO lookup (ignoring dithering for golden reference) From 029df375f58a9f87150c5f4dcc3dad995cf17934 Mon Sep 17 00:00:00 2001 From: JunghwanNA <70629228+shaun0927@users.noreply.github.com> Date: Thu, 16 Apr 2026 12:27:10 +0900 Subject: [PATCH 40/57] fix(test): break on unknown signal in count_concat_bits When an unknown signal is encountered, total is set to -1 but the loop continues.

FPGA: Drive gpio_dig6 from host_agc_enable instead of tied low, making the FPGA register the single source of truth for AGC state. MCU: Change ADAR1000_AGC constructor default from enabled(true) to enabled(false) so boot state matches FPGA reset default (AGC off). Read DIG_6 GPIO every frame with 2-frame confirmation debounce to sync outerAgc.enabled — prevents single-sample glitch from causing spurious AGC state transitions.

The debounce is load-bearing for the "prevents a single-sample glitch" guarantee in the PR body, but no existing test enforces its structure — test_mcu_reads_dig6_before_agc_gate only checks that HAL_GPIO_ReadPin(FPGA_DIG6, ...) and `outerAgc.enabled =` appear somewhere in main.cpp, which a naive direct assignment would still pass. Add test_mcu_dig6_debounce_guards_enable_assignment to TestTier1AgcCrossLayerInvariant, verifying four structural invariants of the debounce: 1. Current DIG_6 sample captured in a local variable 2. Static previous-frame variable defaulting to false (matches FPGA boot: host_agc_enable resets 0) 3. outerAgc.enabled assignment gated by `now == prev` 4.

From 8e1b3f22d28ef02b24a0ab87fa49591f7614d21f Mon Sep 17 00:00:00 2001 From: Serhii Date: Thu, 16 Apr 2026 22:12:23 +0300 Subject: [PATCH 52/57] chore(mcu): remove dead C-style adar1000 driver The firmware uses the C++ ADAR1000_Manager class exclusively. The C-style driver pair (adar1000.c, 693 LoC; adar1000.h, 294 LoC) has no external call sites: grep -rn "Adar_Set|Adar_Read|Adar_Write|Adar_Soft" 9_Firmware grep -rn "AdarDevice|AdarBiasCurrents|AdarDeviceInfo" 9_Firmware Both return hits only inside adar1000.c/h themselves. ADAR1000_Manager.h has its own copies of REG_CH1_*, REG_INTERFACE_CONFIG_A, etc. and does not include adar1000.h. main.cpp had a lone #include "adar1000.h" but referenced no symbols from it; the REG_* macros it uses resolve through ADAR1000_Manager.h on the next line. No behaviour change: the deleted code was unreachable. Side note on #90: adar1000.c contained a second copy of the REG_CH1_* + (channel & 0x03) channel-rotation pattern tracked in #90 (lines 349, 397-398, 472, 520-521). This commit does not fix #90 -- the live path in ADAR1000_Manager.cpp still needs the channel-index fix -- but it removes the dormant copy so the bug has one less place to hide.

Every call to adarSetRxPhase / adarSetTxPhase therefore wrote (I=0x00, Q=0x00) to registers 0x21/0x23 (Rx) and 0x32/0x34 (Tx) regardless of the requested phase state, leaving beam steering completely non-functional in firmware. This commit: * Populates VM_I[128] and VM_Q[128] from ADAR1000 datasheet Rev. B Tables 13-16 (p.34) on a uniform 2.8125 deg grid (360 / 128 states). Byte format: bits[7:6] reserved 0, bit[5] polarity (1 = positive lobe), bits[4:0] 5-bit unsigned magnitude - exactly as specified. * Removes VM_GAIN[128] declaration and (empty) definition. The ADAR1000 has no separate VM gain register; per-channel VGA gain is set via CHx_RX_GAIN (0x10-0x13) / CHx_TX_GAIN (0x1C-0x1F) by adarSetRxVgaGain / adarSetTxVgaGain. VM_GAIN was never populated, never read anywhere in the firmware, and its presence falsely suggested a missing scaling step in the signal path. * Adds 9_Firmware/tests/cross_layer/adar1000_vm_reference.py: an independently-derived ground-truth module containing the full datasheet table plus byte-format / uniform-grid / quadrant-symmetry / cardinal-point invariant checkers and a tolerant C array parser. * Adds TestTier2Adar1000VmTableGroundTruth (9 tests) to test_cross_layer_contract.py, including a tokenising C/C++ comment+string stripper used by the VM_GAIN reintroduction guard, and an adversarial self-test that corrupts one byte and asserts the comparison detects it (defends against silent bypass via future fixture/parser refactors). Adversarially validated: removing the firmware definitions, flipping a single byte, or reintroducing VM_GAIN as code each cause the suite to fail; restoring causes it to pass. VM_GAIN appearing inside string literals or comments correctly does NOT trip the guard. Closes the empty-table half of the ADAR1000 phase-control bug class. The separate channel-rotation issue (#90) will be addressed in a follow-up PR. Refs: 7_Components Datasheets and Application notes/ADAR1000.pdf Rev.
