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
A complete AI-native platform from natural language specification to fabrication-ready output.
Describe your circuit in plain English. Our custom fine-tuned model generates synthesizable Verilog instantly.
Automated testing: syntax checks, functional simulation, timing analysis, edge cases, coverage, and DRC/LVS.
One-click synthesis to fabrication-ready GDSII using OpenLane2 and the SKY130 PDK. 130nm today, 45nm soon.
What used to take a team of engineers months can now be prototyped in a single session.
Custom fine-tuned model trained on 25,000+ verified HDL designs, continuously retrained. Not a GPT wrapper.
Students, researchers, and startups. No EDA experience required — just describe what you want to build.
Four steps from idea to silicon.
Tell the AI what you want to build in natural language.
AI generates synthesizable Verilog/VHDL with testbenches.
6 autonomous agents test and validate your design.
Generate GDSII layout ready for tape-out.
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.
