Welcome Sergiy Nesterenko of Quilter.ai!
Just prior to recording, Chris saw that Dave had been talking about a different “AI autorouter”Configuration on Quilter is currently pretty simple (not a lotSergiy worked at SpaceX in 2014 doing a bunch of boards for testing“PCBs were the tail end of the design, so it became the critical path”Check out some of the public designs on the Quliter BlogQuilter has remade the schematic of the OpenMV camera. This reworked board is indicative of the kinds of boards they can handle.Generally sub-300 MHz, Sub 2AQuilter has a full time EE on staff who helps try out different designs and give feedback.They can parellelize designs by sending them off to a cluster for processing.Chris noted that it felt similar to Place and Route on an FPGA.Quilter doesn’t currently enforce “octolinear traces”, so the traces aren’t straight lines.It makes it possible to detect generative designs, like on the “QPlayer” exampleThe toold helps by defining manufacturing constraints for you, specifically around available board houses.Cost of computeHow do you balance the problem of knowledge? Chris and Dave discussed this for newer engineers in episode 625“What is the job of a PCB?” (perfectly replicate a schematic)Quilter is doing additional checks, including solving for Maxwell’s equations and ThermodynamicsThere are decisions to make within the routing algorithm, ie. Should they enforce “star ground”?When starting out, there was skepticism around code compilers! But over time people came to trust them more and more.How can you try out Quilter? Sign up for waitlist! The best candidat designs will be:Sub 2000 pinssub 100 partssub 100Mhzsub 2AOpen source designsAll the boards on the site have no human inputWhen trying out the service, many customers don’t trust the first board (but later they start to)Spits boards back out as the same file format, they currently support KiCad, Altium, EagleNASA story designing S band antennaWhen starting with new boards, the tool will import outlines by parsing layers in KiCad / Altium / Eagle.Reconsidering different elemetns of a design (constraints)Relaxing constraints (physics)Software modelsWhy don’t some of these tools exist in layout software? Specifically simulation and physics engines.Many do! (Ansys, TDK, etc). Often the cost isn’t justified for simpler boards, so people go without.Feeding back real world squishiness into the modelCosts – Not yet set, but there will be different tiers for hobbyists and open source designs. Sergiy mentioned $50/month for non-enterprise, but it seems like it’s much too early to tell.Check out more on the site at quilter.ai
