udsxml2tex 0.44.0

Convert AUTOSAR DCM/CanTp/DEM arxml to LaTeX UDS (ISO 14229 / 15765) specification documents and ISO 22901-1 ODX/PDX

udsxml2tex

AUTOSAR DCM/CanTp/DEM ARXML → ISO 14229 (UDS) / ISO 15765 / ISO 22901-1 (ODX/PDX) specification documents.

udsxml2tex parses AUTOSAR diagnostic ARXML (DCM, CanTp, DEM, DoIP, COM, AP) and renders a complete UDS specification in LaTeX / PDF / HTML / Markdown / RST / CSV / YAML / JSON / DOCX, plus ASAM ODX 2.2.0 / PDX (ISO 22901-1) for industry diagnostic tooling.

It also ships a local browser UI (--serve) that one-clicks an entire BSW software repository through the pipeline, auto-detecting single-ECU vs multi-ECU layouts.

Install

pip install udsxml2tex                  # core (LaTeX / Markdown / JSON / YAML)
pip install udsxml2tex[web]             # browser UI (--serve)
pip install udsxml2tex[llm]             # LLM analysis (Anthropic + OpenAI / Ollama)
pip install udsxml2tex[ecu-test]        # CAN/ISO-TP hardware testing
pip install udsxml2tex[all]             # everything

Other extras: yaml, watch, docx, lsp, progress, rich, viz.

A LaTeX distribution (TeX Live / MiKTeX with xelatex for CJK) is required to compile generated .tex to PDF. The HTML output renders standalone.

Quick start

# Single ARXML → LaTeX
udsxml2tex dcm.arxml -o spec.tex

# Merge DCM + CanTp + DEM
udsxml2tex dcm.arxml cantp.arxml --dem dem.arxml -o spec.tex

# Auto-discover everything under a BSW repo (CLI mirror of the browser UI)
udsxml2tex --repo /path/to/bsw-project -o spec.tex
udsxml2tex --repo /path/to/bsw-project --repo-dry-run     # show classification

# Output formats
udsxml2tex dcm.arxml --format html  -o spec.html
udsxml2tex dcm.arxml --format md    -o spec.md
udsxml2tex dcm.arxml --format pdx   -o ecu.pdx            # ISO 22901-1 PDX
udsxml2tex dcm.arxml --pdf                                 # compile to PDF

# Multi-language output (English / German / Japanese in one run)
udsxml2tex dcm.arxml --langs en,ja,de -o spec.md --format md

# Validation, diff, multi-ECU systems
udsxml2tex dcm.arxml --validate
udsxml2tex new.arxml --diff old.arxml
udsxml2tex --system system.yaml --system-output-dir out/   # 1+1 / gateway

# Requirement traceability (DOORS CSV → implementation coverage chapter)
udsxml2tex dcm.arxml --requirements doors_export.csv -o spec.tex
udsxml2tex dcm.arxml --requirements doors_export.csv --req-use-llm -o spec.md --format md

# Browser UI
udsxml2tex --serve                                         # http://127.0.0.1:8765

Python API

from udsxml2tex import ArxmlParser, TexGenerator, validate, diff_specs

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

print(validate(spec).summary())                # ISO 14229-1 consistency
print(diff_specs(spec_a, spec_b).to_markdown())

Features

Coverage

• DCM (ISO 14229-1) — sessions, security, all 24 standard services, DIDs, routines, DTCs, memory ranges, IO control / periodic / dynamic DIDs, Authentication, ResponseOnEvent, LinkControl, multi-client.
• CanTp (ISO 15765-2) — channels, BS/STmin, N_As/Bs/Cs/Ar/Br/Cr, addressing.
• DEM (ISO 14229-1 §11) — DTC config, OBD/WWH-OBD, freeze frames, extended data, operation cycles, indicators, combined DTCs.
• DoIP (ISO 13400), Communication ARXML, Adaptive Platform service interfaces.
• C/C++ source scanning — DID/RID global variables (transitive depth ≤3).
• Bootloader overlay — single document covering Drive + Boot domains via YAML.

Output

• tex (Jinja2 + structured ZIP), pdf (xelatex/latexmk), html (multi-page ZIP with offline Mermaid + NRC ladders), md, rst, csv, yaml, json, docx, odx, pdx.
• Visualizations: heatmaps, timing diagrams, UML sequences, byte-level DID maps, session/security FSMs.

Quality

• --validate — 17 ISO 14229-1 consistency checks.
• --diff — semantic spec diff (ARXML or JSON).
• --requirements FILE.csv — load an IBM DOORS-style requirements export (Object / Acceptance_* / CommentInternal / CommentCustomer / CommentToCustomer), match each requirement against the parsed DID / RID / SID / Session / NRC / DTC / SecurityLevel set, and append a "Requirement Traceability" chapter to tex / html / md / rst output. Heuristic identifier-extraction by default; --req-use-llm switches to semantic matching via the configured LLM (with per-row heuristic fallback on failure). Flags Accepted but not implemented as errors, Conditionally Accepted rows as warnings.
• --iso-version {2006,2013,2020} — drop features outside the chosen revision.
• --autosar-compat-report — flag features postdating the detected AUTOSAR release.
• Schema export: JSON Schema (draft-07), Pydantic v2 model source.

LLM analysis ([llm] extra)

• --llm-summarize, --llm-query, --llm-nrc-descriptions, --llm-translate.
• Backends: Anthropic Claude API or any OpenAI-compatible server (Ollama, llama.cpp, vLLM, OpenRouter, Azure). One-shot setup: udsxml2tex --bootstrap-ollama (Linux/macOS).

ECU hardware testing ([ecu-test] extra)

• Auto-generates UDS test cases from the parsed spec, executes over CAN / ISO-TP via python-can. Heuristic generator or formal --ecu-formal state-machine explorer (all-transitions coverage). HTML / JUnit XML / CSV / coverage reports.

Multi-ECU systems

• Declarative YAML config (--system) for redundant / gateway-with-forwarder topologies, per-ECU spec + integration document, ARXML coverage-gap routing inference, cross-ECU validator.

Browser UI (--serve, [web] extra)

• Local FastAPI server with three tabs:
  • Generate — pick a BSW repository folder; the server uploads UDS-relevant files (.arxml, .c, .h, .yaml, .json), classifies each ARXML by AUTOSAR module, auto-detects single vs multi-ECU, and generates the chosen format. format=tex ZIPs include a compiled spec.pdf when xelatex is on PATH; otherwise the UI flags the failure (and the ZIP carries a PDF_NOT_COMPILED.txt with the underlying reason).
  • Chat — multi-turn LLM Q&A (Anthropic / Ollama / OpenAI-compatible) with streaming responses; spec is cached server-side per session.
  • ECU Test — drive CAN/ISO-TP test runs from the browser.

Tooling

• Interactive wizard (-I), config files (--config), file watching (--watch), parallel parse, incremental cache, XSD validation, pytest plugin (uds_spec fixture), LSP server, shell completion, plugin system (ParserPlugin / GeneratorPlugin), i18n (en / de / ja with bilingual --lang ja+en mode + multi-language --langs en,ja,de).

Distribution

• Docker image (TeX Live + udsxml2tex[all]).
• GitHub Action (Marketplace-ready).
• pre-commit hooks (validate / regen PDF / regen TeX ZIP).
• VS Code extension (right-click .arxml → generate / validate / diff / LLM).
