udsdoc 0.74.0

Generate UDS (ISO 14229 / 15765) specification documents and ISO 22901-1 ODX/PDX from AUTOSAR DCM/CanTp/DEM ARXML (formerly udsxml2tex)

udsdoc

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

udsdoc parses AUTOSAR diagnostic ARXML (DCM, CanTp, DEM, DoIP, COM, AP) and renders a complete UDS specification in LaTeX / PDF / HTML / Markdown / RST, plus ASAM ODX 2.2.0 / PDX (ISO 22901-1) for diagnostic tooling. Drive it from the command line or a local browser UI — both run the same pipeline.

Renamed from udsxml2tex in v0.66.0. The old package, udsxml2tex CLI, UDSXML2TEX_* env vars and pre-commit hook ids keep working as deprecated aliases until v1.0.

Install

pip install udsdoc          # core (LaTeX / Markdown / RST)
pip install udsdoc[web]     # browser UI (--serve) + inline SVG figures
pip install udsdoc[all]     # everything

PDF output needs a LaTeX distribution with xelatex (TeX Live / MiKTeX). The [all] extra pulls in every optional feature (browser UI, LLM analysis, ECU hardware testing, and more).

Command line

udsdoc dcm.arxml -o spec.tex                              # single ARXML → LaTeX
udsdoc dcm.arxml cantp.arxml --dem dem.arxml -o spec.tex  # merge modules
udsdoc --repo /path/to/bsw-project -o spec.tex            # auto-discover a BSW repo
udsdoc dcm.arxml --format html -o spec.html               # other formats: html, md, rst, pdx
udsdoc dcm.arxml --pdf                                    # compile to PDF
udsdoc dcm.arxml --lang en+ja -o spec.tex                 # stacked multi-language output

Python API:

from udsdoc import ArxmlParser, TexGenerator

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

Browser UI

pip install udsdoc[web]
udsdoc --serve            # opens http://127.0.0.1:8765

A local server with four tabs in the sidebar:

• Generate — point it at a BSW repository folder (or load a built-in sample bundle). The server scans every ARXML / C file, classifies the Dcm / CanTp / Dem modules and auto-detects single- vs multi-ECU. Pick output language(s), then Parse & Preview to inspect the spec and Generate & Download a LaTeX ZIP (with spec.pdf when xelatex is available) — or Export ODX / PDX for CANalyzer / CANoe. An optional Compliance Matrix CSV adds a requirements-compliance chapter.
• Spec — parsed sessions, services, DIDs, RIDs and DTCs as browsable tables.
• Chat — ask questions about the loaded spec via an LLM (Anthropic / OpenAI-compatible / Ollama).
• About — version and build info.
