Now generating GDSII layouts with OpenLane2 + SKY130

Build Chips with Natural Language

From prompt to fabrication-ready silicon. OpenCores turns your ideas into synthesizable HDL code and GDSII layouts — in minutes, not months.

Trusted by researchers at MIT, Stanford, UC Berkeley, Georgia Tech, Carnegie Mellon, KIT, and TU Delft

Everything you need to design silicon

A complete AI-native platform from natural language specification to fabrication-ready output.

AI HDL Generation

Describe your circuit in plain English. Our custom fine-tuned model generates synthesizable Verilog instantly.

6 Verification Agents

Automated testing: syntax checks, functional simulation, timing analysis, edge cases, coverage, and DRC/LVS.

GDSII Layout

One-click synthesis to fabrication-ready GDSII using OpenLane2 and the SKY130 PDK. 130nm today, 45nm soon.

Minutes, Not Months

What used to take a team of engineers months can now be prototyped in a single session.

Proprietary AI Engine

Custom fine-tuned model trained on 25,000+ verified HDL designs, continuously retrained. Not a GPT wrapper.

Built for Everyone

Students, researchers, and startups. No EDA experience required — just describe what you want to build.

How It Works

Four steps from idea to silicon.

01

Describe

Tell the AI what you want to build in natural language.

02

Generate

AI generates synthesizable Verilog/VHDL with testbenches.

03

Verify

6 autonomous agents test and validate your design.

04

Fabricate

Generate GDSII layout ready for tape-out.

Powered by a proprietary AI engine

OpenCores is built on a custom fine-tuned model trained on over 25,000 verified VHDL and Verilog designs — and continuously retrained as new designs are verified and validated through our platform.

Claude 4.6 serves as the orchestration layer, managing multi-step reasoning, planning, and user interaction. Each model does what it does best.
