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
udsxml2texin v0.66.0. The old package,udsxml2texCLI,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.pdfwhenxelatexis 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.
