    Interesting that on their current leaderboard (https://eebench.org/), GPT-5.6 Sol scores just above GPT-5.4 but below GPT-5.5, the only benchmark that shows that 5.6 is worse than 5.5 on something?

    That the table contains what seems to be absolute numbers for score, cost/task, time/task and output tokens, makes it seem like they've only made one run for each task/model combo, but that can't be right, right? I don't see any mentions of how many times they run each task, so if it's just one run per task/model, isn't this more noisy than useful?

    A personal data point: I had Claude Opus 4.8 design a fairly textbook circuit that outputs a monochrome image burned in an EEPROM over standard 640x480 VGA using only 74 series logic and GALs. It designed the circuit and GAL code, and I did the routing, and got it made through JLC for $6. After it came back, there was one error that was not caught, which I could blue-wire, and it works just fine otherwise. I was fairly impressed.

      Claude is surprisingly good at discrete digital design with 74xxx, wonder what it trained on. Did you run it on anything else digital?
      • Neywiny30 minutes ago
        They're 60 years old. The amount of training data on them is endless. Books, textbooks, videos, blog posts. The problem is when you want you do something that doesn't have 60 years of freely available documentation of their functions and applications

    I got a flexpcb that validates in JLC and PCBWay DRC tools from the KiCAD MCP Server and Codex.

    I have yet to order any or program it, but it was enough to make me push on with a PCB art project for ST-style guitar pickguards - no netlist, no problems.

    I'm also foolishly toying with NeXTBus dev boards for the Cube. Is it cursed? Probably. https://github.com/itomato/NeXTBus-Dev-Board

      Flying home today and got DHL notification that my vibe PCBs are on my porch. Now to try to program, bring up, and see if it works this weekend. $178 for 5 assembled units from PCBway to run this dumb experiment.
    • thearn4an hour ago
      I've gone through this same workflow and had success all the way through DRC ruleset passing with JLCPCB-based settings, ordering, fab, and use. Board was ordered with PCBA (they did assembly of the stock components) and I did SMD for just the oddball module/ICs they don't stock. Works exactly to design.

      My boards are for hobby use and are ridiculously simple though compared to anything professional (breakout boards for specific components in FPV drone video transmission subsystems). That's probably an important detail. I think its like anything else in AI right now. It can do it 90% of the time but that 10% can be really rough and if its a task you can't do or verify yourself, you won't know the difference.

  • alex7o29 minutes ago
    I have a circuit board on my bench designed and ordered from china for 1h (manufacturing+ shipping took 14days), fable designed it I think or sol don't remember anymore but it was in claude code. I told it to benchmark different kicad autoroute tools and I picked the routes I liked the best, with a bit of changes. It feels like magic to be able to go from idea toa physical thing in such a short amount of time. The board works I made some mistakes the ai had made some mistakes but mostly stuff I could fix with some soldering, also one parts datasheet was wrong but I couldn't have known that without ai.

    But I started like others, I would build manually, then run drc then sleep on it and check again and ask an llm to double check for me then order. Llms catch quite a few things but like with code like to make things more complicated than that have to be.

  • johnboiles4 minutes ago
    Yes. I just made one with Fusion and Codex.
  • andrewchambers2 hours ago
    I think the new Astra computer use demos show that the models might be able to do things like inspection of real world objects if given a camera.

    Super excited to see real world feedback added into the agent loops we have gotten used to working with. Could you let the model print and test the circuit boards it is prototyping with a jig?

    • david_rugaexan hour ago
      In July I was struggling with writing DIY Rust firmware for an e-ink screen. I mistakenly thought I'd ordered an Inkplate 6 ED060SC7 and actually had the later version, which confounded my efforts. I was also mistaken about the pixel resolution.

      The way I found this out is I propped it up next to a webcam so it was more or less full frame, and I had the (then new) Fable write a python script to bezier warp the camera capture to a flat projection of the screen. At that point I couldn't address the whole screen. Once I'd guided the capture script I just left the LLM overnight with the instruction to get full control confirmed by a capture round trip, and it was meaningfully finished in a couple of hours. I don't really have the skills to attempt that myself in a reasonable time frame.

    • exe3429 minutes ago
      I don't know about pcbs but i gave chat gpt a picture of my window to help design a mesh screen frame to hold the feline hostage in, and it gave a fairly convincing impression of understanding what was going on, although at one point it thought the window swung inwards (it's an outie).
  • rpcope12 hours ago
    Just as some anecdatum, I've tried this a couple of times over the last few years. 2024-2025, no body could generate anything of any sort of complexity, however maybe around the Opus 4.7 timeline, I tried having it generate some relatively simple and one slightly more complex circuit around 8-bit PIC micros, and was very pleasantly surprised. The schematics for simpler stuff is usually OK, often with some of the kind of crazy belt-and-suspenders stuff you see in code (how many decoupling caps do I actually need here, Claude?), and PCB layout has basically been terrible every time I've tried it.

    Recent models can generate mostly competent schematics if you're using well known parts, feed them data sheets (and you _must_ feed them the errata too) and it's not too complex. Any complexity analog or RF, everything falls down quickly if you know what you're looking at. Maybe Astra will do better? There's still so much implicit knowledge that a good designer (not me by a long shot, but I know a little) will bake into a board, and even as cheap as JCLPCB is now, you don't want to have to spin a half dozen revs because Claude or Codex hallucinated. It will be genuinely interesting to see what happens on this front.

      I never thought about it until now, but as someone with zero skill in this domain I feel interested in making my own vibetronics now.

    At the very least, you can (and probably should) put a plaintext netlist and BOM into an LLM to triple-check your work.

    It will use the part datasheets and decent EE logic to cross reference pins and parts and polarities and generally check that SMD caps and resistors have realistic specifications for their footprint, switching regulators and communication ICs are configured correctly (e.g. when you have resistor settings for an ethernet PHY indicating 100Base-T and RMII, you also won't need TX/RX 2 and 3 and two clocks and a COL net, which it would check), all nets are named and linked correctly, buses have the correct and consistent termination, and so on.

    It's game over once AI figures out autorouting.

  • boznz2 hours ago
    I have tried to use AI on this from GPT3, documenting a few of the attempts on my blog. They know the datasheets and the theory enough to be extremely useful at the start, but the most recent ones are becoming scary good. Routing a PCB is certainly a bit more than joining some wires, you have to accommodate power traces, ground loops, component overlap and all the various RF tricks and tips, but I do believe we are less than a year from prompt to full assembly including enclosure.
  • krupan44 minutes ago
    I'm confused. Who made this benchmark and why? It is fascinating to me that people are putting this much work into trying to measure and evaluate LLMs when we've never gone to this level for humans. Sounds like they also built a harness/feedback loop so the LLM knows if it's doing a good job? Again, why didn't anyone ever do this for human engineers?
    • iopapa22 minutes ago
      We spent a lot time evaluating which model is the best to use in our atopile agent harness and thought the benchmark and results are interesting enough to share.

      Evaluating a model for specific use-cases like this that are bit more broad scope than a lot of typical microbenchmarks turned out to be quite the challenge.

      Determining deterministically what a "good" electrical design is non-trivial and most electrical-engineers rely on good ol' intuition and decade long experience, so we tried to formalize it.

      The only reason it was somewhat possible within a reasonable amount of effort is because atopile provides most of the complicated infrastructure for the benchmark: constraint solver, simulation, code-first electronics modeling, erc & drc checks, high level models of passive electronics components etc

    • lexicality34 minutes ago
      > I'm confused. Who made this benchmark and why?

      It's a thinly veiled advert for Atopile. I don't know if it's a company behind it or just someone with a lot of money to spend on advertising since their about page (and docs) both 404, and the "packages" link sends you to a login screen that tries to unlock 1password. I guess claude can make circuit boards but not functioning websites?

    • codekansas41 minutes ago
      Humans learn differently from LLMs. LLMs already contain most of the information they need to be able to do PCB layout from reading the entire internet, but they need this kind of fast feedback loop to learn how to extract and use that information in the right way. Humans learn to act at the same time they learn knowledge.
    • bbmatryoshka43 minutes ago
      because human engineers are not reproducible, so having an accurate measure of the skills of one of them has a much lower utility return (those benchmarks are very expensive to run, and making them for humans will be at least as much expensive)

    • throwaway219450an hour ago
      For stuff like this, definitely. It’s already exciting. Claude et al are surprisingly competent with real hardware. I’ve also had good success debugging basic issues with micros - not via the debugger, but giving datasheet and written analysis. I’m sure it could do things like capture from a connected oscilloscope (Salaeae have an MCP integration for their logic tools). Also for SPICE which I never bother with because the tools always felt stuck in the 90s, but having some serious automated analog review would be nice. I’m really excited to play with peripherals like the RP2040 or Beaglebone real time logic blocks, or improving/adding real USB support instead of USB serial.

      For circuits I would trust a netlist or DRC/ERC review, checking a design against reference circuit values, probably not placement as that tends to be guided straight from a datasheet where it makes a difference and I like the artistic side of it.

    • cozzydan hour ago
      that's FPGA firmware isn't it?
  • dubbie992 hours ago
    I have found that AI is great for sorting out your libraries, drawing and helping double check footprints managing your BOM. I still draw my schematics and layout my boards. I haven’t found it any good for those tasks yet. There are too many stupid errors it makes. I do get it to review my work though and often it catches things I have missed.
  • amelius2 hours ago
    I'm excited by the option in Astra to route PCBs.

    The next pain-point is sourcing the components from Digikey, LCSC, etc., and finding suitable substitutes if necessary.

    Of course this assumes the LLMs can already read datasheets because that's the biggest pain-point in designing electronics. It's like filling out tax forms.

    Finally it would be great if LLMs could extract simulation models from datasheets!

    • iopapaan hour ago
      Sourcing parts has been a huge motivation for this. We are still pretty jarred by the supply chain crisis a few years ago. Having the ability to formally verify that an alternative part fulfills the original design constraints is huge.

      Not sure whether you played with llm datasheet extraction lately, but they are working their way up there. Even started reasoning about curves and footnotes.

      Where do you think is the biggest pain point: part discovery, datasheet verification or substitute determination?

      Eurisko was used for VLSI chip design, then used rules discovered there to design TCS Traveler winning fleet.

      It is unbelievable how artificial intelligence walk in circles.

    • nickff2 hours ago
      Routing is the easiest part of layout, and there have been auto-routers (which mostly worked) for a long time now; the difficult task is in placing components, and adjusting those placements.
      • amelius2 hours ago
        Sure, I was just using "route" to mean also floorplanning because that's what Astra's routing tool also does. Not sure how they name it. Sorry if I was sloppy.
        • nickff2 hours ago
          Not at all, but the term for routing and placing the components is ‘layout’. Floorplanning usually refers to the laying out of larger blocks of the circuit (with the blocks themselves already having been laid-out).
          • ameliusan hour ago
            Yes but I'm not so concerned with how people name these steps.
  • Anil0809an hour ago
    Yes — this is already possible to a useful degree. I’ve been using tscircuit, where you can describe circuits in code and use AI agents to generate and iterate on schematics and PCB layouts. I’ve seen designs from this workflow go all the way to fabricated, working hardware.
  • dennis163842 hours ago
    If you give it a real solver to drive and business constraints to operate under, it will do pretty good job (which is to map your business rules to constraints and balanced costs, develop deterministic tests, probabilistic tests, acceptance gates, all boring stuff).
    • iopapaan hour ago
      Really excited about constraint solvers making a comeback! Especially after seeing Z3 getting a mention in anthropics fermat post. EEbench is using atopile's internal constraint solver for engineering parameters (think operating temperature, voltage ranges, stacked tolerances etc).

      Mostly focused on BOM, schematics, and firmware now but slowly expanding to circuit boards if we feel we can deliver real value there. Early experiments with Astra are promising

  • ChrisMarshallNY43 minutes ago
    Interesting. AI may be pretty good at managing the gazillion different things that make up circuit boards.

    Frankly, I am surprised that it isn't already a solved problem, as we've had silicon compilers, for many years, and I always figured that IC design is more difficult than PCB.

    • hdhdbdbdxk27 minutes ago
      Digital silicon design is fairly simple in principle. It's hard because there are billions of transistors to route

      PCB design on the other hand more often then not has outside constrains like mechanical, thermal an RF design

    Have tried this a few times. While AI has been helpful in talking through component choices and other topics, it’s consistently been a spectacular fail each time in actually designing the board.

    I’ve had similar results asking AI to design 3D models for 3D printing.

    “Coach me on optimizing error on my printer”… helps.

    “Build me a print ready file to these specs.”… it’s like a drunk cat attacked my computer. Just confidently puts out total nonsense.

    Works very well with EAGLE XML files, especially if you give it the EAGLE.DTD schema that CadSoft provides. Both .sch and .brd files can be extensively manipulated by Claude (and likely everybody else at this point.)
  • mschuster9139 minutes ago
    The submission reeks of LLM tells (especially the "UI" just looks straight like the usual Claude slop).

    Anyway... the posed question reminds me of an anecdote I cannot find because Google is contaminated to hell and beyond, some researchers a decade ago let a machine-learning algorithm loose on an FPGA, and it "found" a design that worked but made no sense, because it exploited unique physical features of this specific chip.
