Add SoftwareFPGA class that imports golden_reference functions to replicate the FPGA pipeline in software, enabling bit-accurate replay of raw IQ, FPGA co-sim, and HDF5 recordings through the same dashboard path as live data. 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.

V7-specific unit tests for the PLFM Radar GUI V7 modules.
|
|
|
|
Tests cover:
|
|
- v7.models: RadarTarget, RadarSettings, GPSData, ProcessingConfig
|
|
- v7.processing: RadarProcessor, USBPacketParser, apply_pitch_correction
|
|
- v7.workers: polar_to_geographic
|
|
- v7.hardware: STM32USBInterface (basic), production protocol re-exports
|
|
|
|
Does NOT require a running Qt event loop — only unit-testable components.
|
|
Run with: python -m unittest test_v7 -v
