* @file diag_log.h
* @brief Bring-up diagnostic logging macros for AERIS-10 radar system.
*
* Provides timestamped, subsystem-tagged diagnostic output over USART3.
* All output is observation-only instrumentation -- no behavioral changes.
*
* Usage:
* #include "diag_log.h"
* DIAG("LO", "TX init returned %d", ret);
* DIAG_WARN("CLK", "PLL2 not locked after %lu ms", timeout);
* DIAG_ERR("PA", "IDQ out of range: %d mA", idq_ma);
* DIAG_REG("LO", "TX reg 0x58", reg_val);
* DIAG_GPIO("LO", "TX_LKDET", port, pin);
*
* Compile-time control:
* #define DIAG_DISABLE -- suppress all DIAG output
* #define DIAG_VERBOSE -- include file:line in every message
*
* @author AERIS-10 Bring-up Instrumentation

/*******************************************************************************
* test_bug10_spi_cs_not_toggled.c
*
* Bug #10 (FIXED): stm32_spi_write_and_read() never toggled chip select.
* Since TX and RX ADF4382A share SPI4, every register write hit BOTH PLLs
* simultaneously.
*
* Post-fix behavior:
* 1. Manager_Init creates stm32_spi_extra structs with the correct CS
* port (GPIOG) and pin for each device (TX_CS_Pin, RX_CS_Pin).
* 2. spi_param.extra points to a stm32_spi_extra with cs_port != NULL,
* so stm32_spi_write_and_read() will assert/deassert CS around
* each transfer.
*
* Note: The actual SPI CS toggling is in stm32_spi.c at the platform level.
* This test verifies that the manager correctly provisions the CS metadata
* that stm32_spi.c uses.

* both TX and RX devices, mirroring EZSync's trigger pattern. With
* timed_sync_setup already programmed, the devices synchronize their output
* dividers to the SYNCP/SYNCN clock edge when sw_sync is asserted.
*
* Test strategy (post-fix):
* 1. Initialize manager with SYNC_METHOD_TIMED.
* 2. Reset spy log, call TriggerTimedSync().
* 3. Verify 4 SPY_ADF4382_SET_SW_SYNC records (TX set, RX set, TX clear,
* RX clear) — same count as EZSync.
* 4. Verify the set/clear ordering is correct.

// adc_clk_mmcm.v — MMCME2 Jitter-Cleaning Wrapper for AD9484 400 MHz DCO
//
// PURPOSE:
// Replaces the direct BUFG on the ADC data clock output (adc_dco) with an
// MMCME2_ADV configured for 1:1 frequency (400 MHz in → 400 MHz out) with
// jitter attenuation via the PLL feedback loop.
//
// CURRENT ARCHITECTURE (ad9484_interface_400m.v):
// adc_dco_p/n → IBUFDS → BUFIO (drives IDDR only, near-zero delay)
// → BUFG (drives all fabric 400 MHz logic)
//
// NEW ARCHITECTURE (this module replaces the BUFG path):
// adc_dco_p/n → IBUFDS → BUFIO (unchanged — drives IDDR only)
// → MMCME2 CLKIN1 → CLKOUT0 → BUFG (fabric 400 MHz)
//
// BENEFITS:
// 1. Jitter attenuation: MMCM PLL loop filters input jitter from ~50 ps
// to ~20-30 ps output jitter, reducing clock uncertainty by ~20 ps.
// 2. Phase control: CLKOUT0_PHASE can fine-tune phase offset if needed.
// 3. Locked indicator: mmcm_locked output enables proper reset sequencing.
// 4. Expected WNS improvement: +20-40 ps on the 400 MHz CIC critical path.
//
// MMCM CONFIGURATION (Artix-7 XC7A200T-2):
// CLKIN1 = 400 MHz (from IBUFDS output)
// DIVCLK_DIVIDE = 1
// CLKFBOUT_MULT_F = 2.0 → VCO = 400 * 2 = 800 MHz (range: 600-1200 MHz)
// CLKOUT0_DIVIDE_F = 2.0 → CLKOUT0 = 800 / 2 = 400 MHz
// CLKFBOUT → BUFG → CLKFBIN (internal feedback for best jitter performance)
//
// INTEGRATION:
// This module is a DROP-IN replacement for the BUFG in ad9484_interface_400m.v.
// See adc_clk_mmcm_integration.md for step-by-step instructions.
//
// SIMULATION:
// Under `ifdef SIMULATION, this module passes the clock through a simple

# ADC Clock MMCM Integration Guide
## Overview
`adc_clk_mmcm.v` is a drop-in MMCME2_ADV wrapper that replaces the direct BUFG
on the 400 MHz ADC data clock output with a jitter-cleaning PLL loop.
### Current clock path (Build 18)
```
adc_dco_p/n → IBUFDS → BUFIO (drives IDDR only — near-zero delay)
→ BUFG (drives all fabric 400 MHz logic)
```
### New clock path (with MMCM)
```
adc_dco_p/n → IBUFDS → BUFIO (unchanged — drives IDDR only)
→ MMCME2 CLKIN1 → CLKOUT0 → BUFG (fabric 400 MHz)
→ CLKFBOUT → BUFG → CLKFBIN (feedback)
```
## Expected Timing Improvement
| Parameter | Before (Build 18) | After (estimated) |
|-----------|-------------------|-------------------|
| Input jitter | 50 ps | 50 ps (unchanged) |
| Output jitter (MMCM) | N/A | ~20-30 ps |
| Clock uncertainty | 43 ps | ~25 ps |
| WNS (setup, 400 MHz) | +0.062 ns | ~+0.08 to +0.10 ns |
| WHS (hold, 100 MHz) | +0.059 ns | unchanged |
The improvement comes from reduced clock uncertainty in the Vivado timing
analysis. The MMCM's PLL loop attenuates the input jitter, so Vivado deducts
less uncertainty from the timing budget.
## MMCM Configuration
```
CLKIN1 = 400 MHz (2.500 ns)
DIVCLK_DIVIDE = 1
CLKFBOUT_MULT_F = 2.0 → VCO = 800 MHz
CLKOUT0_DIVIDE_F = 2.0 → Output = 400 MHz
BANDWIDTH = HIGH (maximum jitter filtering)
```
VCO at 800 MHz is well within the Artix-7 -2 speed grade range (600–1200 MHz).
## Resource Cost
| Resource | Count | Notes |
|----------|-------|-------|
| MMCME2_ADV | 1 | Was 0/10, now 1/10 |
| BUFG | +1 (feedback) | Was 4/32, now 5/32 |
| FFs | 0 | No additional fabric registers |
## Integration Steps
### Step 1: Modify `ad9484_interface_400m.v`
Replace the BUFG instantiation with `adc_clk_mmcm`:
```verilog
// REMOVE these lines (65-69):
// BUFG bufg_dco (
// .I(adc_dco),
// .O(adc_dco_buffered)
// );
// assign adc_dco_bufg = adc_dco_buffered;
// ADD this instead:
wire mmcm_locked;
wire adc_dco_mmcm;
adc_clk_mmcm mmcm_inst (
.clk_in (adc_dco), // From IBUFDS output
.reset_n (reset_n),
.clk_400m_out (adc_dco_mmcm), // Jitter-cleaned 400 MHz
.mmcm_locked (mmcm_locked)
);
// Use MMCM output for all fabric logic
wire adc_dco_buffered = adc_dco_mmcm;
assign adc_dco_bufg = adc_dco_buffered;
```
### Step 2: Gate reset on MMCM lock (recommended)
In `ad9484_interface_400m.v`, modify the reset synchronizer to require MMCM lock:
```verilog
// Change the reset synchronizer input from:
// always @(posedge adc_dco_buffered or negedge reset_n) begin
// if (!reset_n)
// reset_sync_400m <= 2'b00;
// else
// reset_sync_400m <= {reset_sync_400m[0], 1'b1};
// end
// To:
wire reset_n_gated = reset_n & mmcm_locked;
always @(posedge adc_dco_buffered or negedge reset_n_gated) begin
if (!reset_n_gated)
reset_sync_400m <= 2'b00;
else
reset_sync_400m <= {reset_sync_400m[0], 1'b1};
end
```
This ensures the 400 MHz domain stays in reset until the MMCM has locked and
the clock is stable. Without this, the first ~10 µs after power-up (before
MMCM lock) could produce glitchy clock edges.
### Step 3: Add constraint file
Add `constraints/adc_clk_mmcm.xdc` to the Vivado project. Uncomment the
constraints and adjust hierarchy paths based on your actual instantiation.
Key constraints to uncomment:
1. `create_generated_clock` (or verify Vivado auto-creates it)
2. `set_max_delay` between `adc_dco_p` and `clk_400m_mmcm`
3. `set_false_path` between `clk_400m_mmcm` and other clock domains
4. `set_false_path` on `LOCKED` output
### Step 4: Add to build script
In the Tcl build script, add the new source file:
```tcl
read_verilog adc_clk_mmcm.v
read_xdc constraints/adc_clk_mmcm.xdc
```
### Step 5: Verify
After building:
1. Check `report_clocks` — should show the new MMCM-derived clock
2. Check `report_clock_interaction` — verify no unexpected crossings
3. Check WNS on the `adc_dco_p` / MMCM clock group — should improve
4. Check MMCM locked in ILA during bring-up
## BUFIO Compatibility Note
The BUFIO path for IDDR capture is **not affected** by this change. BUFIO
drives only IOB primitives (IDDR) and cannot go through an MMCM. The BUFIO
continues to use the raw IBUFDS output with near-zero insertion delay, which
is correct for source-synchronous DDR capture.
The re-registration from BUFIO domain to BUFG domain (lines 105-108 of
`ad9484_interface_400m.v`) now crosses from the raw `adc_dco_p` clock to the
MMCM-derived clock. Since both are frequency-matched and the MMCM is locked
to the input, this is a safe single-register transfer. The `set_max_delay`
constraint in the XDC ensures Vivado verifies this.
## Simulation
Under `SIMULATION` define (iverilog), the module passes the clock straight
through with a simulated lock delay of ~4096 cycles. This matches the
current testbench behavior — no changes to any testbenches needed.
## Rollback
To revert: simply restore the original BUFG in `ad9484_interface_400m.v` and
remove `adc_clk_mmcm.v` + `constraints/adc_clk_mmcm.xdc` from the project.
No other files are affected.

/**
* cfar_ca.v
*
* Cell-Averaging CFAR (Constant False Alarm Rate) Detector
* for the AERIS-10 phased-array radar.
*
* Replaces the simple magnitude threshold detector in radar_system_top.v
* (lines 474-514) with a proper adaptive-threshold CFAR algorithm.
*
* Architecture:
* Phase 1 (BUFFER): As Doppler processor outputs arrive, compute |I|+|Q|
* magnitude and store in BRAM. Address = {range_bin, doppler_bin}.
* When CFAR is disabled, applies simple threshold pass-through.
*
* Phase 2 (CFAR): After frame_complete pulse from Doppler processor,
* process each Doppler column independently:
* a) Read 64 magnitudes from BRAM for one Doppler bin (ST_COL_LOAD)
* b) Compute initial sliding window sums (ST_CFAR_INIT)
* c) Slide CUT through all 64 range bins:
* - 3 sub-cycles per CUT:
* ST_CFAR_THR: register noise_sum (mode select + cross-multiply)
* ST_CFAR_MUL: compute alpha * noise_sum_reg in DSP
* ST_CFAR_CMP: compare CUT magnitude against threshold + update window
* d) Advance to next Doppler column (ST_COL_NEXT)
*
* CFAR Modes (cfg_cfar_mode):
* 2'b00 = CA-CFAR: noise = leading_sum + lagging_sum
* 2'b01 = GO-CFAR: noise = max(leading_sum * lag_cnt, lagging_sum * lead_cnt)
* normalized — picks larger average
* 2'b10 = SO-CFAR: noise = min(leading_sum * lag_cnt, lagging_sum * lead_cnt)
* 2'b11 = Reserved (falls back to CA-CFAR)
*
* Threshold computation:
* threshold = (alpha * noise_sum) >> ALPHA_FRAC_BITS
* Host sets alpha in Q4.4 fixed-point, pre-compensated for training cell count.
* Example: for T=8 cells per side (16 total), desired Pfa=1e-4:
* alpha_statistical ≈ 4.88
* alpha_fpga = alpha_statistical / 16 = 0.305 → Q4.4 ≈ 0x05
* Or host can set alpha per training cell if it accounts for count.
*
* Edge handling:
* At range boundaries where the full window doesn't fit, only available
* training cells are used. The noise estimate naturally reduces, raising
* false alarm rate at edges — acceptable for radar (edge bins are
* typically clutter).
*
* Timing:
* Phase 2 takes ~(66 + T + 3*64) * 32 ≈ 8500 cycles per frame @ 100 MHz
* = 85 µs. Frame period @ PRF=1932 Hz, 32 chirps = 16.6 ms. Fits easily.
* (3 cycles per CUT due to pipeline: THR → MUL → CMP)
*
* Resources:
* - 1 BRAM18K for magnitude buffer (2048 x 17 bits)
* - 1 DSP48 for alpha multiply
* - ~300 LUTs for FSM + sliding window + comparators
*
* Clock domain: clk (100 MHz, same as Doppler processor)

# AERIS-10 FPGA Constraint Files
## Four Targets
| File | Device | Package | Purpose |
|------|--------|---------|---------|
| `xc7a50t_ftg256.xdc` | XC7A50T-2FTG256I | FTG256 (256-ball BGA) | Upstream author's board (copy of `cntrt.xdc`) |
| `xc7a200t_fbg484.xdc` | XC7A200T-2FBG484I | FBG484 (484-ball BGA) | Production board (new PCB design) |
| `te0712_te0701_minimal.xdc` | XC7A200T-2FBG484I | FBG484 (484-ball BGA) | Trenz dev split target (minimal clock/reset + LEDs/status) |
| `te0713_te0701_minimal.xdc` | XC7A200T-2FBG484C | FBG484 (484-ball BGA) | Trenz alternate SoM target (minimal clock + FMC status outputs) |
## Why Four Files
The upstream prototype uses a smaller XC7A50T in an FTG256 package. The production
AERIS-10 radar migrates to the XC7A200T for more logic, BRAM, and DSP resources.
The two devices have completely different packages and pin names, so each needs its
own constraint file.
The Trenz TE0712/TE0701 path uses the same FPGA part as production but different board
pinout and peripherals. The dev target is split into its own top wrapper
(`radar_system_top_te0712_dev.v`) and minimal constraints file to avoid accidental mixing
of production pin assignments during bring-up.
The Trenz TE0713/TE0701 path supports situations where TE0712 lead time is prohibitive.
TE0713 uses XC7A200T-2FBG484C (commercial temp grade) and requires separate clock mapping,
so it has its own dev top and XDC.
## Bank Voltage Assignments
### XC7A50T-FTG256 (Upstream)
| Bank | VCCO | Signals |
|------|------|---------|
| 0 | 3.3V | JTAG, flash CS |
| 14 | 3.3V | ADC LVDS (LVDS_33), SPI flash |
| 15 | 3.3V | DAC, clocks, STM32 3.3V SPI, DIG bus |
| 34 | 1.8V | ADAR1000 control, SPI 1.8V side |
| 35 | 3.3V | Unused (no signal connections) |
### XC7A200T-FBG484 (Production)
| Bank | VCCO | Used/Avail | Signals |
|------|------|------------|---------|
| 13 | 3.3V | 17/35 | Debug overflow (doppler bins, range bins, status) |
| 14 | 2.5V | 19/50 | ADC LVDS_25 + DIFF_TERM, ADC power-down |
| 15 | 3.3V | 27/50 | System clocks (100M, 120M), DAC, RF, STM32 3.3V SPI, DIG bus |
| 16 | 3.3V | 50/50 | FT601 USB 3.0 (32-bit data + byte enable + control) |
| 34 | 1.8V | 19/50 | ADAR1000 beamformer control, SPI 1.8V side |
| 35 | 3.3V | 50/50 | Status outputs (beam position, chirp, doppler data bus) |
## Signal Differences Between Targets
| Signal | Upstream (FTG256) | Production (FBG484) |
|--------|-------------------|---------------------|
| FT601 USB | Unwired (chip placed, no nets) | Fully wired, Bank 16 |
| `dac_clk` | Not connected (DAC clocked by AD9523 directly) | Routed, FPGA drives DAC |
| `ft601_be` width | `[1:0]` in upstream RTL | `[3:0]` (RTL updated) |
| ADC LVDS standard | LVDS_33 (3.3V bank) | LVDS_25 (2.5V bank, better quality) |
| Status/debug outputs | No physical pins (commented out) | All routed to Banks 35 + 13 |
## How to Select in Vivado
In the Vivado project, only one target XDC should be active at a time:
1. Add both files to the project: `File > Add Sources > Add Constraints`
2. In the Sources panel, right-click the XDC you do NOT want and select
`Set File Properties > Enabled = false` (or remove it from the active
constraint set)
3. Alternatively, use two separate constraint sets and switch between them
For TCL-based flows:
```tcl
# For production target:
read_xdc constraints/xc7a200t_fbg484.xdc
# For upstream target:
read_xdc constraints/xc7a50t_ftg256.xdc
# For Trenz TE0712/TE0701 split target:
read_xdc constraints/te0712_te0701_minimal.xdc
# For Trenz TE0713/TE0701 split target:
read_xdc constraints/te0713_te0701_minimal.xdc
```
## Top Modules by Target
| Target | Top module | Notes |
|--------|------------|-------|
| Upstream FTG256 | `radar_system_top` | Legacy board support |
| Production FBG484 | `radar_system_top` | Main AERIS-10 board |
| Trenz TE0712/TE0701 | `radar_system_top_te0712_dev` | Minimal bring-up wrapper while pinout/peripherals are migrated |
| Trenz TE0713/TE0701 | `radar_system_top_te0713_dev` | Alternate SoM wrapper (TE0713 clock mapping) |
## Trenz Split Status
- `constraints/te0712_te0701_minimal.xdc` currently includes verified TE0712 pins:
- `clk_100m` -> `R4` (TE0712 `CLK1B[0]`, 50 MHz source)
- `reset_n` -> `T3` (TE0712 reset pin)
- `user_led` and `system_status` are now mapped to TE0701 FMC LA lines through TE0712 B16
package pins (GPIO export path, not TE0701 onboard LED D1..D8).
- Temporary `NSTD-1`/`UCIO-1` severity downgrades were removed after pin assignment.
### Current GPIO Export Map
| Port | TE0712 package pin | TE0712 net | TE0701 FMC net |
|------|---------------------|------------|----------------|
| `user_led[0]` | `A19` | `B16_L17_N` | `FMC_LA14_N` |
| `user_led[1]` | `A18` | `B16_L17_P` | `FMC_LA14_P` |
| `user_led[2]` | `F20` | `B16_L18_N` | `FMC_LA13_N` |
| `user_led[3]` | `F19` | `B16_L18_P` | `FMC_LA13_P` |
| `system_status[0]` | `F18` | `B16_L15_P` | `FMC_LA5_N` |
| `system_status[1]` | `E18` | `B16_L15_N` | `FMC_LA5_P` |
| `system_status[2]` | `C22` | `B16_L20_P` | `FMC_LA6_N` |
| `system_status[3]` | `B22` | `B16_L20_N` | `FMC_LA6_P` |
Note: FMC direction/N/P labeling must be validated against TE0701 connector orientation
and I/O Planner before final hardware sign-off.
## Trenz Batch Build
Use the dedicated script for the split dev target:
```bash
vivado -mode batch -source scripts/build_te0712_dev.tcl
# TE0713/TE0701 target
vivado -mode batch -source scripts/build_te0713_dev.tcl
```
Outputs:
- Project directory: `vivado_te0712_dev/`
- Reports: `vivado_te0712_dev/reports/`
- Top module: `radar_system_top_te0712_dev`
- Constraint file: `constraints/te0712_te0701_minimal.xdc`
TE0713 outputs:
- Project directory: `vivado_te0713_dev/`
- Reports: `vivado_te0713_dev/reports/`
- Top module: `radar_system_top_te0713_dev`
- Constraint file: `constraints/te0713_te0701_minimal.xdc`
## Notes
- The production XDC pin assignments are **recommended** for the new PCB.
The PCB designer should follow this allocation.
- Bank 16 (FT601) is fully utilized at 50/50 pins. No room for expansion
on that bank.
- Bank 35 (status/debug) is also at capacity (50/50). Additional debug
signals should use Bank 13 spare pins (18 remaining).
- Clock inputs are placed on MRCC (Multi-Region Clock Capable) pins to
ensure proper clock tree access.

# adc_clk_mmcm.xdc — Supplementary constraints for MMCM ADC clock path
#
# These constraints augment the existing adc_dco_p clock definitions when the
# adc_clk_mmcm module is integrated into ad9484_interface_400m.v.
#
# USAGE:
# Add this file to the Vivado project AFTER the main production XDC.
# The main XDC still defines create_clock on adc_dco_p (the physical input).
# Vivado automatically creates a generated clock on the MMCM output;
# these constraints handle CDC paths for the new clock topology.
#
# HIERARCHY: rx_inst/adc/mmcm_inst/...
# ============================================================================
# --------------------------------------------------------------------------
# MMCM Output Clock — use Vivado's auto-generated clock name
# --------------------------------------------------------------------------
# Vivado auto-creates a generated clock named 'clk_mmcm_out0' on the MMCM
# CLKOUT0 net. We do NOT create_generated_clock here (that would create a
# second clock on the same net, causing the CDC false paths below to bind
# to the wrong clock and leave clk_mmcm_out0 uncovered — exactly the bug
# that caused Build 19's -0.011 ns WNS on the CDC_FIR gray-code path).
# All constraints below reference 'clk_mmcm_out0' directly.
# --------------------------------------------------------------------------
# CDC: BUFIO domain (adc_dco_p) ↔ MMCM output domain (clk_mmcm_out0)
# --------------------------------------------------------------------------
# The IDDR outputs are captured by BUFIO (adc_dco_p clock), then re-registered
# into the MMCM BUFG domain in ad9484_interface_400m.v.
# These clocks are frequency-matched and phase-related (MMCM is locked to
# adc_dco_p), so the single register transfer is safe. We use max_delay
# (one period) to ensure the tools verify the transfer fits within one cycle
# without over-constraining with full inter-clock setup/hold analysis.

# CDC: MMCM output domain ↔ other clock domains
# --------------------------------------------------------------------------
# The existing false paths in the production XDC reference adc_dco_p, which
# now only covers the BUFIO/IDDR domain. The MMCM output clock (which drives
# all fabric 400 MHz logic) needs its own false path declarations.

# --------------------------------------------------------------------------
# MMCM Locked — asynchronous status signal, no timing paths needed
# --------------------------------------------------------------------------
# LOCKED is not a valid timing startpoint (it's a combinational output of the
# MMCM primitive). Use -through instead of -from to waive all paths that pass
# through the LOCKED net. This avoids the CRITICAL WARNING from Build 19/20.
set_false_path -through [get_pins rx_inst/adc/mmcm_inst/mmcm_adc_400m/LOCKED]
# --------------------------------------------------------------------------
# Hold waiver for BUFIO→MMCM domain transfer (if Vivado flags hold violations)
# --------------------------------------------------------------------------
# The existing hold waiver for BUFIO source-synchronous capture stays:
# set_false_path -hold -from [get_ports {adc_d_p[*]}] -to [get_clocks adc_dco_p]
#
# The MMCM BUFG re-registration of IDDR outputs: since BUFIO and MMCM output
# are derived from the same IBUFDS source, hold is inherently met (MMCM adds
# insertion delay). If Vivado flags hold violations on this transfer, uncomment:
# set_false_path -hold -from [get_clocks adc_dco_p] -to [get_clocks clk_mmcm_out0]

#
# ALTERNATIVE APPROACH: If the post-synthesis ILA insertion script

# Usage:
# 1. Add this file to the Vivado project as a constraint source
# 2. Re-run synthesis (nets will be preserved with MARK_DEBUG)
# 3. Use Vivado GUI: Flow > Set Up Debug, or run insert_ila_probes.tcl
#
# NOTE: mark_debug must be applied to RTL-level signal names. After
# synthesis, Vivado will propagate the attribute to the corresponding
# netlist nets regardless of renaming or flattening.

# --------------------------------------------------------------------------
# FT601 output timing — source-synchronous, datapath-only constraints
# --------------------------------------------------------------------------
# The FT601 provides its own 100 MHz clock (D_CLK) and samples data on
# the next rising edge of that same clock. The FPGA receives D_CLK through
# IBUF→BUFG (~5 ns insertion), but this insertion delay is COMMON to both
# the data launch (register clocked by BUFG output) and the data capture
# (FT601 sampling on the same physical clock edge).
#
# Using set_output_delay with the real clock creates a false ~5 ns skew
# penalty. Using a virtual clock doesn't help because Vivado still sees
# the IBUF+BUFG insertion on the source side.
#
# Instead, we use set_max_delay -datapath_only to constrain the
# register-to-pad delay directly. The budget is:
# Tperiod(10 ns) - Tsu(2.0 ns) - Tboard_margin(0.5 ns) = 7.5 ns
# This ensures data arrives at the FT601 pad with 2.5 ns margin before
# the next clock edge.
#
# For hold (min delay): We use set_min_delay. The FT601 Th = 0.5 ns.
# The data must not change until 0.5 ns after the CURRENT clock edge.
# Since the register launches on the clock edge and the pad delay is
# always positive (>= 1 ns), hold is inherently met. We set min = 0
# to be safe.

# NOTES ON RTL ADAPTATION FOR FMC BUILD
# --------------------------------------------------------------------------
# The production RTL (usb_data_interface.v) has these ports that need
# handling for the FMC dev build:
#
# 1. ft601_clk_out (output) — ODDR forwarded clock. No FMC return path
# on UMFT601X-B. Leave unconnected or assign to an unused Bank 16 pin.
#
# 2. ft601_txe_n (output reg) — Production PCB artifact. Driven to 1,
# never functionally used. Leave unconstrained (no FMC connection).
#
# 3. ft601_rxf_n (output reg) — Same as txe_n. Leave unconstrained.
#
# 4. ft601_srb[1:0] (input) — FIFO buffer select. Not on UMFT601X-B FMC.
# Tie to 2'b00 in RTL wrapper or via pulldown.
#
# 5. ft601_swb[1:0] (input) — Same as srb. Tie to 2'b00.
#
# 6. ft601_txe (input) — Wired to UMFT601X-B TXE_N (active-low from FT601).
# Polarity works: FSM checks `!ft601_txe` → !LOW=1 → proceed when ready.
#
# 7. ft601_rxf (input) — Wired to UMFT601X-B RXF_N (active-low from FT601).
# Not used in current write-only FSM but correct for future read path.
#
# 8. ft601_reset_n (input in RTL at port level, but also used as
# ft601_reset_n on UMFT601X-B FMC LA10_N). The XDC above constrains
# ft601_reset_n — this is an OUTPUT from FPGA to reset the FT601 chip,
# not the RTL's synchronized reset input. The RTL's ft601_reset_n input
# should be driven by internal logic (e.g., system reset synchronized to
# ft601_clk_in). The FMC pin ft601_reset_n should be a separate port.
#
# RECOMMENDED: Create a thin FMC wrapper module that:
# - Instantiates usb_data_interface with existing port names
# - Ties ft601_srb/ft601_swb to 2'b00
# - Leaves ft601_txe_n/ft601_rxf_n unconnected
# - Assigns ft601_clk_out to an unused pin or removes it
# - Adds ft601_reset_n, ft601_wakeup_n, ft601_gpio0/1 as new top ports

# PCB designer should follow this allocation)
#
# Revision History:
# v1.0 2026-03-16 Initial pin plan from Vivado FBG484 package CSV export.
# Migrated from XC7A50T-FTG256 (upstream cntrt.xdc).
# FT601 USB 3.0 fully wired (32-bit data bus).
# dac_clk output wired (FPGA drives DAC clock).
#
# I/O Bank Voltage Plan:
# Bank 13: VCCO = 3.3V — Debug outputs overflow (doppler debug, range bins)
# Bank 14: VCCO = 2.5V — ADC LVDS (LVDS_25 + DIFF_TERM), ADC control
# Bank 15: VCCO = 3.3V — System clocks (100M MRCC, 120M MRCC), DAC,
# RF control, STM32 3.3V SPI, STM32 DIG bus, reset
# Bank 16: VCCO = 3.3V — FT601 USB 3.0 (32-bit data + 4-bit byte enable +
# control, clock on MRCC)
# Bank 34: VCCO = 1.8V — ADAR1000 beamformer control, SPI 1.8V side
# Bank 35: VCCO = 3.3V — Status outputs (beam position, chirp, doppler
# data bus, system status)
#
# Pin Count Summary:
# Bank 13: 17 used / 35 available (18 spare)
# Bank 14: 19 used / 50 available (31 spare)
# Bank 15: 27 used / 50 available (23 spare)
# Bank 16: 50 used / 50 available (0 spare)
# Bank 34: 19 used / 50 available (31 spare)
# Bank 35: 50 used / 50 available (0 spare)
# TOTAL: 182 used / 285 available
#
# Key Differences from Upstream (XC7A50T-FTG256):
# 1. ADC uses LVDS_25 (2.5V VCCO) instead of LVDS_33 (better signal quality)
# 2. FT601 USB 3.0 is fully wired (Bank 16) — unwired on upstream board
# 3. dac_clk output is routed — unconnected on upstream board
# 4. ft601_be is 4 bits wide [3:0] for 32-bit FT601 mode
# 5. All status/debug outputs have physical pins (Banks 35 + 13)

# FT601 USB 3.0 INTERFACE — ACTIVE: NO PHYSICAL CONNECTIONS
# ============================================================================
# The FT601 chip (U6, FT601Q-B-T) is placed in the Eagle schematic but has
# ZERO net connections — no signals are routed between it and the FPGA.
# Bank 35 (which would logically host FT601 signals) has no signal pins
# connected, only VCCO_35 power.
#
# ALL FT601 constraints are commented out. The RTL module usb_data_interface.v
# instantiates the FT601 interface, but it cannot function without physical
# pin assignments. To use USB, the schematic must be updated to wire the
# FT601 to FPGA Bank 35 pins, and then these constraints can be populated.
#
# Ports affected (from radar_system_top.v):
# ft601_data[31:0], ft601_be[1:0], ft601_txe_n, ft601_rxf_n, ft601_txe,
# ft601_rxf, ft601_wr_n, ft601_rd_n, ft601_oe_n, ft601_siwu_n,
# ft601_srb[1:0], ft601_swb[1:0], ft601_clk_out, ft601_clk_in
#
# TODO: Wire FT601 in schematic, then assign pins here.
# ============================================================================
# ============================================================================
# STATUS / DEBUG OUTPUTS — NO PHYSICAL CONNECTIONS
# ============================================================================
# The following RTL output ports have no corresponding FPGA pins in the
# schematic. The only FPGA→STM32 outputs available are DIG_5 (H11),
# DIG_6 (G12), and DIG_7 (H12) — only 3 pins for potentially 60+ signals.
#
# These constraints are commented out. If status readback is needed, either:
# (a) Multiplex selected status bits onto DIG_5/6/7, or
# (b) Send status data over the SPI interface, or
# (c) Route through USB once FT601 is wired.

# ADDITIONAL NOTES
# ============================================================================
#
# 1. ADC Sampling Clock: FPGA_ADC_CLOCK_P/N (N11/N12) is the 400 MHz LVDS
# clock from AD9523 OUT5 that drives the AD9484. It connects to FPGA MRCC
# pins but is not used as an FPGA clock input — the ADC returns data with
# its own DCO (adc_dco_p/n on N14/P14).
#
# 2. Clock Test: FPGA_CLOCK_TEST (H14) is a 20 MHz LVCMOS output from the
# FPGA, configured by AD9523 OUT7. Not currently used in RTL.
#
# 3. SPI Flash: FPGA_FLASH_CS (E8), FPGA_FLASH_CLK (J13),
# FPGA_FLASH_D0 (J14), D1 (K15), D2 (K16), D3 (L12), unnamed (L13).
# These are typically handled by Vivado bitstream configuration and do
# not need explicit XDC constraints for user logic.
#
# 4. JTAG: FPGA_TCK (L7), FPGA_TDI (N7), FPGA_TDO (N8), FPGA_TMS (M7).
# Dedicated pins — no XDC constraints needed.
#
# 5. dac_clk port: The RTL top module declares `dac_clk` as an output, but
# the physical board wires the DAC clock (AD9708 CLOCK pin) directly from
# the AD9523, not from the FPGA. This port should be removed from the RTL
# or left unconnected. It currently just assigns clk_120m_dac passthrough.

/**
* fft_engine.v
*
* Synthesizable parameterized radix-2 DIT FFT/IFFT engine.
* Iterative single-butterfly architecture with quarter-wave twiddle ROM.
*
* Architecture:
* - LOAD: Accept N input samples, store bit-reversed in BRAM
* - COMPUTE: LOG2N stages x N/2 butterflies, 4-cycle pipeline:
* BF_READ: Present BRAM addresses; register twiddle index
* BF_TW: BRAM data valid → capture; twiddle ROM lookup from
* registered index → capture cos/sin
* BF_MULT2: DSP multiply from registered data + twiddle → PREG
* BF_WRITE: Shift (bit-select from PREG, pure wiring) +
* add/subtract + BRAM writeback
* - OUTPUT: Stream N results (1/N scaling for IFFT)
*
* Twiddle index computed via barrel shift (idx << (LOG2N-1-stage)) instead
* of general multiply, since the stride is always a power of 2.
*
* Data memory uses xpm_memory_tdpram (Xilinx Parameterized Macros) for
* guaranteed BRAM mapping in synthesis. Under `ifdef SIMULATION, a
* behavioral Verilog-2001 model replaces the XPM so the design compiles
* with Icarus Verilog or any non-Xilinx simulator.
*
* Clock domain: single clock (clk), active-low async reset (reset_n).

// Solution: Add explicit registered stages that Vivado can absorb into DSP48E1:
// BREG: coeff_reg[k] — registered copy of coeff[k], feeds DSP48 B-port
// MREG: mult_reg[k] — registered multiply output, feeds DSP48 P-port
