Surfaces the three-point AI usage policy Jason articulated in #106 by
placing it in CONTRIBUTING.md between "Code Standards & Tooling" and
"Running the Test Suites", so first-time AI-assisted contributors see
the expectation in the onboarding doc rather than having to discover
it via issue archaeology. Text is the #106 comment verbatim with two
small typo fixes only (use if AI -> use of AI; doesnt -> doesn't); no
structural or stylistic rewriting.
Per Jason's green light to open this PR in
NawfalMotii79/PLFM_RADAR#106 (comment-4273144522).
Rename radar_dashboard.py -> GUI_V65_Tk.py and add core feature parity
with the v7 PyQt dashboard while keeping Tkinter as the framework:
Replay mode:
- _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
- Failed replay load nulls controller ref to prevent dangling state
Tests: 17 new tests for DemoTarget, DemoSimulator, _ReplayController
CI: all 4 jobs pass (167+21+25+29 = 242 tests)
- Remove xfft_32.v, tb_xfft_32.v, and fft_twiddle_32.mem (dead code
since PR #33 moved Doppler to dual 16-pt FFT architecture)
- Update run_regression.sh: xfft_16 in PROD_RTL, remove xfft_32 from
EXTRA_RTL and all compile commands
- Update tb_fft_engine.v to test with N=16 / fft_twiddle_16.mem
- Update validate_mem_files.py: validate fft_twiddle_16.mem instead of 32
- Update testbenches and golden data from main_cleanup branch to match
dual-16 architecture (tb_doppler_cosim, tb_doppler_realdata,
tb_fullchain_realdata, tb_fullchain_mti_cfar_realdata, tb_system_e2e,
radar_receiver_final, golden_doppler.mem)
- Update CONTRIBUTING.md with full regression test instructions covering
FPGA, MCU, GUI, co-simulation, and formal verification
Regression: 23/23 FPGA, 20/20 MCU, 57/58 GUI, 56/56 mem validation,
all co-sim scenarios PASS.
