# Rapid Silicon

> Fabless semiconductor company (founded 2019, Los Gatos, California) building AI- and
> intelligent-edge-focused FPGAs and embedded FPGA (eFPGA) IP on an open-source technology base.
> Rapid Silicon sells silicon IP and locally installed EDA software. It does not operate a public
> web API, developer portal, or machine-readable API contract.

## Provenance

- Generated by the API Evangelist enrichment pipeline on 2026-08-26 from this repository's apis.yml
  and probe artifacts. This file is NOT published by Rapid Silicon; rapidsilicon.com/llms.txt
  returned HTTP 404 when probed on 2026-08-26.

## Products

- Gemini FPGA family — AI and intelligent-edge focused FPGA devices.
- Vega eFPGA IP — embeddable standalone FPGA IP core with a customizable, scalable architecture
  spanning roughly 1.5K to 100K+ logic cells, with configurable BRAM and DSP MAC tiles, licensed for
  integration into a customer SoC.
- Rapid eFPGA Configurator — self-service tool for sizing Vega eFPGA resources (DSPs, BRAM, logic
  elements) ahead of an IP delivery engagement.
- Raptor Design Suite — RTL-to-bitstream FPGA compiler and GUI covering simulation, synthesis,
  placement, routing, bitstream generation and device configuration. Released by Rapid Silicon under
  GPL3 and described by the company as the first complete commercially available open-source FPGA
  tool-chain.

## Source code

- https://github.com/RapidSilicon — Rapid Silicon's own GitHub organization (12 public repositories,
  chiefly forks of open-source EDA and simulation infrastructure; most recent push 2024-10).
- https://github.com/os-fpga/Raptor — the Raptor Design Suite compiler and GUI. This repository lives
  in the Open-Source FPGA Foundation organization, not in a Rapid Silicon organization; Rapid
  Silicon's own announcements identify Raptor as its tool-chain and this as where it is released.

## API surface

- No OpenAPI, Swagger, GraphQL SDL, AsyncAPI, gRPC/Protobuf or WSDL contract was found for Rapid
  Silicon. Contract discovery probed rapidsilicon.com for /openapi.json, /llms.txt and seven
  /.well-known/ paths (all 404), and code-searched both the RapidSilicon and os-fpga GitHub
  organizations for OpenAPI/Swagger documents (0 results).
- No hosted MCP server, A2A agent card, developer portal, API reference, sandbox, published pricing
  plans or rate-limit documentation was found.
- No first-party client SDK is published on npm, PyPI, RubyGems, crates.io, NuGet, Maven Central or
  pkg.go.dev under a Rapid Silicon name.

## Company web presence

- rapidsilicon.com is still registered to the company (GoDaddy, registry expiry 2027-06-14) and its
  mail exchange still resolves to Microsoft 365, but since 2026-05-25 the web origin returns
  HTTP 301 to https://realdha.com/, a third-party domain-brokerage listing, and HTTP 404 for every
  product, blog and documentation path. There is currently no reachable Rapid Silicon website.
- https://www.linkedin.com/company/rapidsilicon — company page (HTTP 200 on 2026-08-26).
