What we build

Chock, Aegis, and Harbor: one for the agent that writes your code, one for the FPGA it runs on, one for the libraries it builds with.

Chock

A harness that runs AI coding agents inside a sandbox. You set the policy for what an agent may read, run, and change, and its work arrives as a commit you approve.

Aegis

A fully open-source FPGA, from the silicon up. Fabric generation, synthesis, place-and-route, bitstream packing, simulation, and tapeout live in one project. From HDL to GDS, nothing is behind a proprietary wall.

Harbor

A hardware component library in Dart for ROHD, Rapid Open Hardware Development. Reusable, tested hardware building blocks you depend on like any other software package.
