Anvil Docs

An end-to-end, fully open-source FPGA toolchain No proprietary tools, no licenses: synthesize, simulate and program FPGAs with an open flow (F4PGA = Yosys + VPR), driven by a small CLI called Anvil.

Start here

1. Install the toolchain — Ubuntu · WSL2
2. Getting started — from an empty folder to a bitstream on the board
3. Blinky tutorial — your first design, explained step by step

Running on Windows (WSL2)?

The docs are written for native Linux. The few WSL-only steps (forwarding the board's USB) appear as call-outs marked "WSL only" throughout — on native Linux you can skip them.

Why open-source

• No licenses, no lock-in — free to use, modify and share; nothing to expire.
• Transparent — every layer is inspectable, from RTL to bitstream.
