“Whether or not a PCB layout or design is good is computable.”
Our CEO
@sergiynest joined the AI and Design podcast from CMU Human-Computer Interaction Institute hosted by Nikolas Martelaro to talk about why Quilter is taking a different path from most AI tools.
Here are key highlights when it pertains to PCBs design:
1. Imitation of existing designs has a ceiling, physics does not.
A lot of AI tools learn by mimicking human behavior. We all know how powerful it can be for text. For printed circuit boards, if a PCB layout is 99% right, the remaining 1% can still kill your whole board. Moreover, if a model learns from existing expert layouts, how do we know that all of those layouts were optimal?
Quilter starts from physics instead. Whether a layout works can be computed from electromagnetics and thermodynamics. So we optimize against that directly.
2. "Vibe coding" hardware has a hard limit.
For simple boards, yes, hobbyists are experimenting with vibe engineering. We've seen a mechanical engineer with no EE background ship a PCB after a few hours with KiCAD and Quilter. That works when the board is simple and the stakes are low. But for anything with real complexity nobody serious is prompting their way to a validated layout.
3. Constraints are at the heart of layout automation.
Before you can automate anything, you have to capture what "good" means for this specific board. Across a real design, that can be tens of thousands of constraints. No engineer is going to manually capture all of them. Sergiy talked about 3 possible approaches: a chatbot that interrogates you, tables you fill in and verify, or direct selection on the schematic you already know by heart. The truth is nobody has solved how to design the best human-AI interface for that yet, including us.
The discussion went beyond the traditional PCB topics and touched on how to hire engineers in an era where AI tools are expected, why deleting from your design until things break is a better practice than adding features, how to stay focused on one problem when agentic tools make it cheap to build anything.
