  PyPI JSON metadata endpoints (pypi.org/pypi/<pkg>/json) and the GitHub Xilinx organization
  (github.com/Xilinx), queried 2026-09-04.
note: >-
  Xilinx ships no HTTP API client libraries — it has no HTTP API. What it publishes are
  first-party Python packages for its adaptive-computing stack (PYNQ board framework,
  Brevitas quantization, FINN dataflow compiler, RapidWright). Versions and dates below are
  read from each registry's metadata endpoint, not from prose.

  - registry: npm
    note: >-
      npm search for "xilinx" returns only third-party packages (xilt, an unaffiliated
      Bitbucket-hosted build helper). Xilinx publishes no npm scope.
  - registry: maven-central
    note: >-
      search.maven.org timed out on the com.xilinx* group query on 2026-09-04; RapidWright's
      Java artifacts are distributed as GitHub release JARs. version null — not checked
      successfully, recorded as a gap rather than a guess.

    description: Core infrastructure for the FINN dataflow compiler.
    decay_signal: >-
      Last PyPI release 2021-11-04 while github.com/Xilinx/finn is still pushed daily —
      the project moved off PyPI to source installation; the registry copy is abandoned.
  - name: finn
    registry: pypi

    description: >-
      Placeholder release only. FINN (1,046 stars, pushed 2026-09-04) is installed from source
      or via its Docker flow; the PyPI name is a reserved 0.0.1 stub.
  - name: pyxir
    registry: pypi

    description: >-
      Neural-network intermediate-representation bridge used by Vitis AI / TVM.
    note: >-
      official set false deliberately: the PyPI record carries no project URL back to Xilinx
      and only an individual author name, so first-party ownership of the REGISTRY entry is
      not provable from the registry metadata even though github.com/Xilinx/pyxir is Xilinx's.
excluded:
  - name: xrt
    registry: pypi
    reason: >-
      NOT Xilinx. pypi.org/project/xrt is "Ray tracing and wave propagation in x-ray regime"
      by Konstantin Klementiev and Roman Chernikov (xrt.readthedocs.io). The Xilinx Runtime
      (XRT) is distributed as DEB/RPM packages and GitHub releases, not on PyPI.
      A name-only match would have credited Xilinx with another project's package.
  - name: qonnx
    registry: pypi
    reason: >-
      Published from github.com/fastmachinelearning/qonnx, a community organization Xilinx
      contributes to but does not own.
non_registry_distribution:
  - name: XRT (Xilinx Runtime)
    registry: none
    url: https://github.com/Xilinx/XRT/releases
    official: true
    version: 2.25.0
    published: '2026-08-18'
    note: >-
      Distributed as DEB/RPM installers per OS from GitHub releases and the AMD download
      centre — there is no package-registry metadata endpoint to query. Version and date read
      from the GitHub releases API.
