Silicon Lab
Chips, from a spec to signoff.
We design real silicon on the open-source EDA stack — RISC-V processor IP and an agentic compiler that carries a chip from spec to tapeout.
A collective of specialized labs designing an agentic silicon compiler, safety-certifiable RISC-V IP, edge ML, mission-grade avionics, and open source everyone can build on.

Winter Labs runs as a set of focused labs, each attacking a different hard problem — sharing tools, research, and a bias toward autonomy.
A modern harness that makes chip design and tapeout reproducible — and AI agents that drive it from RTL to GDSII.
Verification-first agents that show their work, respect guardrails, and keep humans in the loop where it matters.
Applied ML that survives the real world — models that generalize across datasets and run on constrained edge hardware.
The tooling and libraries we build internally, released as open source for the whole community to build on.
Our agentic silicon compiler owns the whole open-source EDA toolchain — turning intent into a place-and-routed, fabrication-ready design.
Every lab is a self-contained team with its own mandate and projects. Step inside to see what each one is building.
Chips, from a spec to signoff.
We design real silicon on the open-source EDA stack — RISC-V processor IP and an agentic compiler that carries a chip from spec to tapeout.

Autonomous agents for the hardest engineering.
We build agentic systems that own real toolchains — designing chips, enforcing compliance, and accelerating AI at the edge, not just autocompleting.

Machine learning that survives the real world.
We do applied ML research aimed at deployment — models that generalize across datasets and run on constrained edge hardware, not just benchmarks.

Mission systems for the sky.
We build software-defined avionics and mission systems — portable landing aids and flight-path monitoring for demanding, safety-critical operations.

Software we build in the open, for everyone.
We open-source the tooling we build internally — vendor-neutral alternatives to expensive proprietary workflows, free for the whole community.

New frontiers are forming.
We spin up new labs whenever a problem is big enough to deserve one. Something new is condensing — stay close.
Whether it's silicon, capital, or research at the edge of what's possible — we'd love to hear what you're building.
