udsdoc

AUTOSAR DCM/CanTp/DEM ARXML → UDS (ISO 14229) specification documents (LaTeX → PDF) and ASAM ODX 2.2 / PDX (ISO 22901-1).

udsdoc turns AUTOSAR diagnostic ARXML into a complete UDS specification and into ODX/PDX for diagnostic tooling. It offers two front-ends over the same pipeline: a GUI (local browser app) and a CLI (headless, CI/HPC-friendly).

Install

pip install udsdoc          # CLI core (LaTeX / Markdown / RST / ODX / PDX)
pip install udsdoc[web]     # GUI  (udsdoc --serve)
pip install udsdoc[all]     # everything (GUI + LLM verify + ECU testing)

PDF output needs a LaTeX distribution with xelatex (TeX Live / MiKTeX). No pip on the target machine? Grab the self-contained udsdoc.pyz from Releases — it runs with just a Python interpreter (python3 udsdoc.pyz input.arxml -o spec.tex).

GUI version

udsdoc --serve            # opens http://127.0.0.1:8765

Inputs — on the Generate tab, pick a BSW repository folder (or a built-in sample). It auto-discovers the ARXML (Dcm / CanTp / Dem) and the C sources; attach an optional Compliance Matrix CSV (+ a sources YAML) for a requirements-compliance chapter.
Outputs — Generate & Download a LaTeX ZIP that includes a compiled spec.pdf (Tex → PDF), or Export ODX / PDX for CANalyzer / CANoe.
LLM — the LLM tab connects the provider used by Verify Conditionally-Accepted comments: Claude (browser sign-in), ChatGPT / Gemini (paste an API key — the button opens the key page for you), or local Ollama (pick or install an open-source model). Credentials are stored locally under ~/.udsdoc/.

CLI version

# ARXML in → LaTeX + compiled PDF out
udsdoc dcm.arxml cantp.arxml --dem dem.arxml --pdf -o spec.tex

# auto-discover a whole BSW repo (ARXML + C sources)
udsdoc --repo /path/to/bsw-project --pdf -o spec.tex

# DID / RID C sources for variable cross-referencing
udsdoc dcm.arxml --c-source did.c --c-source rid.c -o spec.tex

# Compliance Matrix + verify the concluded OEM↔supplier dialogue vs. the
# implementation, emit ISO 22901-1 PDX
udsdoc dcm.arxml --dem dem.arxml \
    --compliance-matrix matrix.csv --verify --format pdx -o out/spec

Inputs — ARXML as positional arguments (+ --dem), or a whole repository via --repo; C sources via --c-source; requirements via --compliance-matrix (+ --compliance-matrix-sources).
Outputs — --format pdf / --pdf (Tex → PDF), --format pdx (ISO 22901-1 PDX; also tex, tex-zip — the structured multi-file LaTeX project as a ZIP — html, md, rst, odx). Exit codes: 0 ok / 1 runtime error / 2 usage error / 3 quality gate (--verify-strict, --validate, --odx-strict).

Python API:

from udsdoc import ArxmlParser, TexGenerator

spec = ArxmlParser().parse_multi(["dcm.arxml", "cantp.arxml"])
TexGenerator().generate(spec, "spec.tex")

LLM configuration

The Verify feature (does the concluded OEM↔supplier dialogue match the implementation?) works with Anthropic (Claude), any OpenAI-compatible endpoint (OpenAI, Gemini's OpenAI-compatible API, OpenRouter, …) or local Ollama. Configure it once, whichever way suits you:

GUI — the LLM tab: sign in with Claude, paste a ChatGPT / Gemini key, or pick an Ollama model.
Env vars — UDSDOC_LLM_PROVIDER, UDSDOC_LLM_MODEL, UDSDOC_LLM_BASE_URL, UDSDOC_LLM_API_KEY (or a provider-native key such as ANTHROPIC_API_KEY / OPENAI_API_KEY / GEMINI_API_KEY).
CLI flags — --llm-provider, --llm-model, --llm-base-url, --llm-api-key, or --llm-config <file>.
Config file — ~/.udsdoc/llm.json ({"provider", "model", "base_url", "api_key", "timeout"}).

--verify alone runs fully offline (deterministic status / numeric / lexical checks); add --verify-llm to let the LLM judge the prose-ambiguous rows.
