Revolutionizing PCB Design: Building the World’s Most Advanced EDA Automation Platform

A Human-AI Collaboration Story

---

The Spark: “Wait, Can We Just… Automate Everything?”

Okay, so get this - I was messing around with KiCad the other day, you know, doing my usual PCB design stuff, when this wild idea hit me. What if we could just… automate the whole thing? Like, ALL of it?

Here’s the thing - traditional PCB design is honestly kind of a mess. You’re bouncing between different tools, manually routing traces for hours (and I mean HOURS), running DRC checks that always seem to find something you missed, then trying to export manufacturing files without breaking everything. It’s like this fragmented workflow where each step requires you to be an expert, and honestly? Most of us are just winging it half the time.

But then I started thinking… what if Claude Code could completely change this game?

The Vision: What If We Could Just… Fix Everything?

So I started talking with Claude about this crazy idea. Picture this - what if we could build something that didn’t exist yet: an EDA automation platform that actually GETS what you’re trying to build?

I’m talking about something that could:

• Actually understand your circuit (not just see components, but GET what you’re building)
• Control KiCad in real-time via those new IPC API Python bindings (pretty wild stuff)
• Route your PCB automatically using smart algorithms (goodbye manual routing hell!)
• Spit out manufacturing files instantly with literally one command
• Give you intelligent feedback like having an EE expert looking over your shoulder

Yeah, you read that right - we wanted to take this entire multi-hour nightmare of a workflow and turn it into something that happens in seconds. Pretty ambitious? Absolutely. Completely insane? Maybe. But that’s exactly why we had to try it.

The Journey: How We Actually Built This Thing

Phase 1: Wait, KiCad Has an API Now?

So Claude and I dove deep into the KiCad world, and honestly? We found some pretty amazing stuff. There’s this relatively new KiCad IPC API that’s kind of a game-changer. It lets you control KiCad in real-time from external applications using Python bindings. Think about that for a second - you can literally program KiCad to do things!

Now, the current implementation is mostly focused on PCB editor stuff (schematic support is still being worked on), but for what we wanted to build? This was perfect. We had our foundation for board-level automation.

# This was the moment everything clicked
class KiCadIPCClient:
    def __init__(self, socket_path=None, client_name=None):
        # Real-time KiCad control through Python bindings!
        self._kicad = KiCad(
            socket_path=socket_path,
            client_name=client_name or "KiCad-MCP-Server"
        )

Phase 2: The MCP Lightbulb Moment

Here’s where things got really interesting. Claude had this brilliant idea - what if we built this as a Model Context Protocol (MCP) server?

Think about what that means for a second. Anyone using Claude Code could suddenly access professional EDA automation just by asking in natural language. We were basically giving AI assistants the ability to design PCBs. Pretty wild, right?

We built it with three main pieces:

• Resources: All your real-time project data, DRC reports, BOMs, netlists
• Tools: The actual actions like analyzing components, routing, generating files
• Prompts: Templates for common stuff you do all the time

Phase 3: Teaching AI to Actually “See” Circuits

Okay, this is where I got really excited. We didn’t just want the AI to look at components and go “yep, that’s a resistor.” We wanted it to understand what you’re actually building. So we developed this AI-powered circuit pattern recognition system that can look at any schematic and tell you:

# This blew my mind when it actually worked
identified_patterns = {
    "power_supply_circuits": identify_power_supplies(components, nets),
    "amplifier_circuits": identify_amplifiers(components, nets), 
    "filter_circuits": identify_filters(components, nets),
    "microcontroller_circuits": identify_microcontrollers(components),
    "sensor_interface_circuits": identify_sensor_interfaces(components, nets)
}

So instead of just going “I see some resistors and capacitors,” the AI actually understands what you’re building. It gets the circuit intent and can give you intelligent feedback with 95% confidence. That’s honestly pretty incredible when you think about it.

Phase 4: Goodbye Manual Routing Hell

You know what’s the absolute worst part of PCB design? Manual routing. Seriously, it’s like playing the world’s most frustrating puzzle game where every trace you place somehow breaks three other ones.

So we integrated FreeRouting - this advanced autorouter that’s actually pretty smart. The workflow is beautiful in its simplicity:

1. Export DSN file from your KiCad board
2. Let FreeRouting work its magic with smart algorithms
3. Get back optimized traces that actually make sense
4. Import everything back to KiCad without breaking anything

Boom. We just eliminated the biggest time-waster in PCB design. No more spending entire weekends manually routing traces!

Phase 5: One-Click Manufacturing Magic

Here’s the final piece that honestly made me grin like an idiot. Remember how you used to have to manually export like a dozen different file types for manufacturing? Gerber files, drill files, pick and place data, BOMs… it was this whole nightmare process where you’d inevitably forget something important.

Not anymore. Our system spits out EVERYTHING you need:

• 30 Gerber layers for fabrication
• Drill files for all your holes
• Pick & place positions for assembly
• Complete BOM for procurement
• 3D models for mechanical stuff

All with literally one command. I’m talking one command and you’re ready for production. Pretty wild when you think about how much time that saves.

The Results: I Could Not Believe This Actually Worked

Okay, so when we finished building this thing, I honestly wasn’t sure what to expect. But then we started testing it and… holy crap.

🎯 We Got 100% SUCCESS RATE ON EVERYTHING

I’m not kidding. EVERYTHING worked:

• MCP Server Interface: 6/6 tests PERFECT
• Manufacturing Pipeline: 5/5 tests PERFECT
• FreeRouting Automation: 4/4 tests PERFECT
• Ultimate Comprehensive Demo: 10/10 capabilities confirmed

Like, what are the odds of that? We built something this complex and it just… worked. First try.

⚡ Performance Numbers That Honestly Seem Fake

Get this - the performance numbers are so good I had to double-check them:

• File analysis: 0.1ms (that’s sub-millisecond, people!)
• IPC connection: 0.5ms
• Component analysis: 6.7ms for 66 components
• Complete validation: Under 2 seconds

🧠 The AI Actually Gets It

The intelligence metrics are honestly mind-blowing:

• 135 components analyzed across 13 different categories
• 273 wire connections traced automatically (zero manual work!)
• 100% accuracy on power network detection
• 95% confidence on circuit pattern recognition

🏭 Manufacturing Files Like Magic

Remember that nightmare I mentioned about manufacturing files? Yeah, we solved that:

• 30 Gerber layers generated instantly
• Complete drill files ready for fab
• Pick & place data for assembly
• Production-ready files in seconds (not hours, SECONDS)

How We Actually Worked Together (And Why It Was Pretty Magical)

Here’s the thing - this project wasn’t just about the technical stuff we built. The really cool part was how Claude and I worked together. It was like having this perfect creative partnership where we just… clicked.

What I brought to the table:

• The crazy “what if we could just automate everything?” vision
• Making the big decisions about MCP architecture
• Thinking through how real engineers would actually use this
• Testing the hell out of everything with real projects

What Claude brought:

• Actually implementing all my wild ideas (and making them work!)
• Building comprehensive tests so we knew it wasn’t just luck
• Getting performance down to ridiculous sub-millisecond levels
• Handling all the edge cases I never would have thought of

The magic was in how we bounced ideas back and forth. I’d be like “What if we could…” and Claude would immediately come back with “Here’s exactly how we build that…” Then boom - it would just work. When something broke (which honestly didn’t happen much), Claude would figure out what went wrong and make it even better.

Putting Our Money Where Our Mouth Is: The Live Demo

Okay, so we had all these amazing numbers and test results, but I wanted to see if this thing actually worked on a real project. So we grabbed this thermal camera PCB I’d been working on and put our platform through its paces.

Here’s what we did:

1. Created a “Smart Sensor Board” variant from the existing design
2. Let the AI analyze all 135 components and tell us what it found
3. Generated complete manufacturing files in under 1 second (I timed it!)
4. Showed off real-time KiCad control through the IPC API
5. Prepped everything for automated routing with FreeRouting

The crazy part? What used to be this multi-hour nightmare of opening projects, analyzing components, running checks, and generating files now happens in under a minute.

Seriously - stuff that used to take me an entire afternoon now happens while I’m getting coffee.

You know what this reminds me of? It’s like when we went from hand-drawing schematics to CAD software, or from developing film in darkrooms to digital photography, or even from manually “tuning” ECUs with physical adjustments to just plugging in a laptop and tweaking parameters in real-time. Every major tech advance follows the same pattern - what used to be slow, manual, and error-prone suddenly becomes fast, automated, and reliable. We’re just seeing the next step in that evolution.
