proto_decoder.py
Decodes DSI packet content from proto (differential) captures.
Usage:
python3 proto_decoder.py [--cap CAP_NUM] [--dir DATA_DIR] [--compare]
The proto_*_clk and proto_*_dat captures are Ch1-Ch2 and Ch3-Ch4 differential
waveforms at ~50-80 ps/sample. CLK runs continuously at ~215 MHz (430 Mbps DDR).
DAT carries MIPI D-PHY HS data, sampled on both CLK edges.
Decodes:
- DSI long packet header: DI (data type / virtual channel), word count, ECC
- First N payload bytes on lane 0
- Compares two captures to spot differing byte positions (data-shift detection)

Find the start of the post-LP HS burst in the DAT trace.
Updated
2026-04-27 13:58:09 +01:00
single_ended=True — LP files (CH1=CLK+, CH3=DAT0+): detects LP-01/LP-00
as DAT+ < LP_SE_LP01_THRESH_V for ≥ 20 ns, then returns
index 50 ns after the plateau ends (HS common-mode rise).
Search starts at index 0 — LP-11 pre-trigger (~1.2 V)
is well above the threshold so no false matches.
single_ended=False — Proto files (F2=CH3-CH4 differential): LP-01 detected
as diff < -0.5 V for ≥ 20 ns, search from N//4.

Returns index into t_dat just past the SoT preamble, ready for CLK-edge sampling.
Falls back to rolling-std method for HS-triggered captures (differential only).

Full decode of an LP capture (CH1=CLK+, CH3=DAT0+) using single-ended thresholds.
LP files are captured at 10 GSa/s (100 ps/sample, ~23 samples/bit at 432 Mbps) —
sufficient resolution to decode the HS bit stream without a separate proto pass.
Returns a dict with the same structure as decode_capture().

Summarise bit-level anomalies from a decode_capture() result.
Returns {"anomalous": bool, "flags": list[str]}.
Checks:
sync_byte_not_found — 0xB8 not found in any of 8 bit phases →
HS burst may not have started properly
sync_byte_late — 0xB8 found but at byte index > 5 →
garbage precedes sync → possible byte misalignment
