# Xilinx

> Xilinx was an American technology company that developed programmable logic devices (FPGAs,
> Zynq SoCs, Versal adaptive SoCs) and the associated design software, before being acquired by
> AMD in a $50B all-stock deal that closed in February 2022. The Xilinx brand no longer operates
> its own web properties — www.xilinx.com 301-redirects to www.amd.com, docs.xilinx.com to
> docs.amd.com, and support.xilinx.com to adaptivesupport.amd.com. What remains actively
> published under the Xilinx name is its GitHub organization (github.com/Xilinx, 469 public
> repositories, verified), which is where every machine-readable contract in this profile came
> from.

## Provenance
- generated: 2026-09-04
- method: generated
- source: apis.yml + artifacts in this repository (github.com/api-evangelist/xilinx)
- No provider-published llms.txt exists. www.xilinx.com/llms.txt returns 404; docs.amd.com/llms.txt
  returns HTTP 200 with an HTML single-page-app shell, which is a soft miss, not a document.

## API surface
Xilinx publishes **no HTTP/REST API and no OpenAPI definition**. Contract discovery was run
against every host this record knows (www.xilinx.com, xilinx.github.io) for /openapi.json,
/swagger.json, /api-docs, /docs, GraphQL introspection, MCP tools/list, OGC conformance and
A2A agent cards; every probe missed. The company's machine-readable contracts are Protocol
Buffers service definitions, not web APIs.

## Contracts (gRPC / Protocol Buffers)
Six proto3 services, 108 RPCs, from the first-party Xilinx/PYNQ repository (BSD-3-Clause).
Together they are the PYNQ remote-device protocol: a gRPC server on the Zynq/RFSoC board,
a PYNQ client on the host.
- [RemoteDevice](grpc/xilinx-pynq-remote-device.proto): 7 RPCs — bitstream download, PL clock
  configuration, file read/write/exists, shutdown. Streaming download/readfile/writefile.
- [Mmio](grpc/xilinx-pynq-mmio.proto): 3 RPCs — memory-mapped register get/read/write.
- [Gpio](grpc/xilinx-pynq-gpio.proto): 7 RPCs — sysfs GPIO export, read, write, unexport.
- [RemoteBuffer](grpc/xilinx-pynq-buffer.proto): 9 RPCs — DMA buffer allocate/free, cache flush
  and invalidate, physical/virtual address translation. Streaming read and write.
- [Xrfdc](grpc/xilinx-pynq-xrfdc.proto): 77 RPCs — RFSoC RF Data Converter tile/block control,
  mixer and NCO settings, PLL and FIFO status.
- [Xrfclk](grpc/xilinx-pynq-xrfclk.proto): 5 RPCs — LMK/LMX RF clock device discovery and
  register programming.
- Index and per-service summary: [grpc/xilinx-grpc.yml](grpc/xilinx-grpc.yml)
These are on-device endpoints. There is no vendor-operated host, so there is no base URL and
nothing an agent can call over the public internet.

## Packages and SDKs
- [packages/xilinx-packages.yml](packages/xilinx-packages.yml) — eight first-party PyPI packages
  with registry-read versions and dates: pynq 3.1.2 (2025-09-30), brevitas 0.13.2 (2026-08-28),
  rapidwright 2026.1.0 (2026-06-30), pynq-dpu 2.5.1 (2022-11-08), pynq-helloworld 3.0.0,
  finn-base 0.0.3, finn 0.0.1 (stub), pyxir 0.0.1. XRT ships as DEB/RPM, release 2.25.0
  (2026-08-18). Note: the PyPI package named `xrt` is an unrelated x-ray tracing project and
  is explicitly excluded.

## Command line
- [cli/xilinx-cli.yml](cli/xilinx-cli.yml) — xrt-smi (program, validate, examine, configure,
  reset) and xclbinutil, documented at xilinx.github.io/XRT.

## Other artifacts in this profile
- [changelog/xilinx-changelog.yml](changelog/xilinx-changelog.yml) — release history read from
  the GitHub releases API for PYNQ, Brevitas and XRT.
- [conventions/xilinx-conventions.yml](conventions/xilinx-conventions.yml) — gRPC envelope,
  idempotency (none), reversibility.
- [conformance/xilinx-conformance.yml](conformance/xilinx-conformance.yml)
- [lifecycle/xilinx-lifecycle.yml](lifecycle/xilinx-lifecycle.yml)
- [security/xilinx-domain-security.yml](security/xilinx-domain-security.yml)
- [well-known/xilinx-well-known.yml](well-known/xilinx-well-known.yml) — a recorded absence.
- [mcp/xilinx-mcp.yml](mcp/xilinx-mcp.yml) — candidate only; nobody ships a Xilinx MCP server.

## What is NOT here, and why
No agent card, no MCP server, no AsyncAPI, no webhooks, no OAuth scopes, no sandbox, no
published rate limits and no published plans. This is a semiconductor design-tools business
absorbed into a parent company; its developer surface is compilers, runtimes and boards, not
a callable web platform. These absences are measured, not assumed.
