We built an agentic system that converts prompts into silicon using LangGraph. You provide a specification of the ASIC that you want, and a team of agents architects, designs, and tapes out a GDS.

You can inspect the waveform to confirm pixels are moving, and you can look at the GDS to confirm that everything is routed: http://coresmith.ai/demo. CoreSmith iterates on the design until foundry DRC checks are clean — this means you can tape out your own ASIC on TinyTapeout.com or other shuttle programs.

CoreSmith is built on LangGraph. We define three stages: architecture, frontend design, and backend design. In each stage, we define a set of agents. For example: the RTL agent writes the RTL, the DV agent verifies it, and the Chip Lead triages the result.

Then we specify rules between agents: if the design has RTL bugs, LangGraph activates the RTL agent again. If the design has a test bench bug, LangGraph activates the DV agent. Coresmith works in a loop until the IP is functional.

We specify dozens of agents for each step of the chip design pipeline, all the way to GDS and foundry DRC checks.

CoreSmith is the OpenCode of VLSI.

We are building a community of people passionate about agentic silicon design.
