  Rapid Silicon is a fabless semiconductor company founded in 2019 and headquartered in Los Gatos,
  California, building AI- and intelligent-edge-focused FPGAs and embedded FPGA (eFPGA) IP on an
  open-source technology base. Its product line covers the Gemini FPGA family, the Vega eFPGA IP core
  (a customizable, scalable embeddable FPGA fabric from roughly 1.5K to 100K+ logic cells with
  configurable BRAM and DSP MAC tiles), and the Rapid eFPGA Configurator for self-service eFPGA
  resource sizing. Design work is done in the Raptor Design Suite, the company's RTL-to-bitstream
  EDA tool-chain covering simulation, synthesis, placement, routing, bitstream generation and device
  configuration, released under GPL3 as what the company describes as the first complete
  commercially available open-source FPGA tool-chain. Rapid Silicon raised a $15M seed round in 2021
  and a $30M Series A in January 2023 from Cambium Capital Partners and Chengwei Capital, and is led
  by chairman and CEO Naveed Sherwani. The company's products are silicon IP and locally installed
  design software rather than a hosted service, so it publishes no public web API, developer portal
  or machine-readable API contract; as of 2026-05-25 its rapidsilicon.com website no longer serves
  company content and redirects to a domain-brokerage page.

  description: >-
    Rapid Silicon's Raptor RTL-to-bitstream FPGA compiler and GUI, open-sourced by the company under
    GPL3. It is published in the github.com/os-fpga organization, which belongs to the Open-Source
    FPGA Foundation rather than to Rapid Silicon itself; the company's own press releases identify
    Raptor as its tool-chain and this repository as where it is released.

  detail: >-
    Rapid Silicon sells eFPGA IP cores and a GPL3 desktop RTL-to-bitstream tool-chain (Raptor), never
    a hosted service, and ships no developer program of any kind — and its corporate site is now gone
    on top of that: since 2026-05-25 rapidsilicon.com 301s to realdha.com, a domain-brokerage listing,
    and returns 404 for /openapi.json, /llms.txt, every former product and documentation path, and all
    seven /.well-known/ paths, while a GitHub code search across both the RapidSilicon and os-fpga
    organizations returns zero OpenAPI or Swagger documents.
