A Floorplan Without the Village

August 31, 2026 • By Shivaram Mysore

Getting a floorplan out of an open flow has meant installing the whole flow. We took the six steps that build one and shipped them as static binaries you can point at your own netlist. Four die sizes explored in under a minute — and on a block whose taped-out DEF we can check against, the rows and tracks match exactly.

Vyges: First Year Anniversary

August 11, 2026 • By Shivaram Mysore

One year ago today, Vyges launched with a claim: silicon should be built like software. A year on, the catalog is open, the sign-off engines are open, and a chip has gone from specification to tapeout using the foundation we set out to build.

Open-Source EDA Now Has a Chiplet Workflow

August 11, 2026 • By Shivaram Mysore

Advanced packaging has been the part of silicon design that open tools could not reach. That changed. You can now describe a chiplet assembly, check that it is structurally sound, check that its die-to-die interfaces actually connect, draw it, and gate CI on all of it — with open-source tools, on your own machine.

An Open Chiplet Flow, End to End, on OpenROAD

August 8, 2026 • By Shivaram Mysore

Assembly description in, verdict and drawing out, with a CI gate at the end. The complete open chiplet flow in one page — plus the five-minute demo where a one-character change kills an entire die-to-die bus and the structural checks stay green.

Your Chiplet Interface Passes Every Open-Source Check. It's Still Dead.

August 5, 2026 • By Shivaram Mysore

Two chips bonded together are only connected if the bumps on their mating faces land on each other and carry the same signals. A one-character mistake left an entire 8-bit die-to-die bus connected to nothing — and every open-source structural check reported the assembly clean. So we built the check that catches it.

Describing and Checking a Chiplet Stack, With Open Tools

August 2, 2026 • By Shivaram Mysore

An assembly is not a design file — it is a description of how several dies are placed, flipped and bonded. OpenROAD's OpenDB made that describable in the open. Here is how to write one, check it, and draw it as a cross-section, from one command line with no GUI.

We Didn't Train the AI. We Taught Our Tools to Explain Themselves.

July 16, 2026 • By Shivaram Mysore

No fine-tuning, no orchestration code. We gave each of Vyges Loom's twenty-plus sign-off engines a clear, typed, machine-readable interface — and an off-the-shelf GPT-4.1 model, connected through MCP, discovered the tools and drove the sign-off flow on its own. Orchestration became a property of the interfaces, not the model — so today's model isn't special, and tomorrow's works too.

How do I use a local SemiKong LLM to drive DRC sign-off?

July 9, 2026 • By Shivaram Mysore

A semiconductor LLM can reason about DRC — it can't run it. This walkthrough points a locally-hosted SemiKong at real DRC on your own hardware, with real captured output on a taped-out IP: the model proposes the tool call, the deterministic vyges-drc engine is the ground truth, and nothing leaves your machine.

Timing Sign-Off for the Open Silicon Era — and Why We Wrote It in Rust

June 25, 2026 • By Shivaram Mysore

Open EDA gave the world synthesis, place-and-route, and DRC — but not commercial-grade timing sign-off. We built it: WNS/TNS with signal integrity, foundry-standard formats, CI-native. And we wrote it in Rust, so it runs natively everywhere from Apple Silicon to Arm64 cloud — with a parallel-by-design architecture that doesn't foreclose the GPU.
