The process of creating symbols is often too rigid and tedious to create schematics that are beautiful. That’s why, today, we’re introducing parametrically programmable schematic symbols in Flux.
That’s why, today, we’re introducing parametrically programmable schematic symbols in Flux.
In modern EDA tools, creating schematics and symbols entails a manual process of drawing rectangles, squares, and lines with a mouse and cursor. Too often, we fight with symbols because they’re so hard to modify. It can feel impossible to create any sort of sane signal convention. Interconnections and signal flow ultimately devolve into lines leaving your symbol’s pins in seemingly random order and direction. How is anyone supposed to make sense of these schematics?
Flux's parametric symbols change how we view schematic symbols by offering you customization and flexibility. With parametric symbols, your team can better organize your schematic symbols by grouping pins based on functionality and logical connection, without needing to physically draw the symbol. Want all GPIO to be grouped together? Maybe you want all power pins to be on the left side of the symbol? Or, do you want all ADC channel pins to be next to each other?
Parametric symbols enable your team to make designs organized and readable. The result is a symbol that isn’t just a square with some lines, it’s a neatly organized, clearly partitioned set of functions that can be easily interpreted by anyone on the team and beyond. Don’t fight with rigid symbols. Instead, organize your symbol as you want, make the signal flow clear and intuitive, and end up with a schematic design that is simple to understand.
Parametric symbols also introduce unprecedented levels of flexibility and customization. Unlike conventional symbols that need to be completely redrawn by hand if changes are desired, parametric symbols are configurable on the fly. No more hassle and wasted time using a drawing tool to rearrange pins.
At Flux, we believe your design should be declarative, not imperative. You should tell your symbols how they could behave - not the other way around. Parametric symbols are our first step in realizing this reality.
Creating parametric symbols in Flux is as simple as filling out property fields in the Inspector Panel. 4 properties determine how the symbol arranges itself:
Once the symbol is created, it can be changed easily by redefining properties to your liking. That means that symbols are dynamic and configurable with little to no effort and wasted time.
To learn more about how to work with parametric symbols in Flux, check out the documentation page.
Parametric symbols are our first step towards a truly declarative workflow with Flux. Soon, you will find declarative workflows integrated into every feature, including the PCB Editor.

{{insert-book-a-demo}}
80% of Fortune 500 companies already have employees using AI like ChatGPT for their everyday work and we’ve all seen how LLMs have been leveraged to write code. But, what about designing and building hardware?
We believe LLMs will revolutionize every step of the hardware development process from initial brainstorming all the way through production. From talking with dozens of enterprise customers across the industry, we’ve learned that you are also excited to leverage AI to streamline tedious tasks, access organization-wide knowledge, reduce design risks, and ultimately ship innovative products faster.
We also learned that enterprise customers are concerned about the security aspects of using an AI platform for hardware development. They want enterprise-grade security, privacy, and white-glove onboarding support. That’s why, today, we’re excited to be launching Flux for the Enterprise!
With Flux Enterprise, we’re finally bringing AI to hardware teams at enterprise companies with Flux Copilot. What is Flux Copilot? It’s conversational AI that lives in your project to augment your design workflow. Think of it like a senior EE that’s always available for you, 24/7.
What makes Flux Copilot different than generic LLMs like ChatGPT is that it has direct knowledge of your project’s bill of materials, netlist connections, datasheets, engineering knowledge, project requirements, and can even understand images like plots, charts, and technical diagrams - and that’s just the beginning.
Since we launched Copilot last year, it has been used by thousands of hardware teams to build PCBs for everything from industrial IoT to boards used in space! Some of our favorite enterprise use cases for Copilot include:
Whatever your use case may be, there’s no doubt that it can improve your hardware workflow to save your organization time and money.

Imagine a future where your most complex PCB design challenges are met with an intelligent AI assistant, capable of handling everything from component selection to compliance checks. Read on to discover how Copilot, embedded within the Flux platform, is turning this vision into a reality, liberating electrical engineers to focus on what truly matters: innovation.
If menial tasks are corroding the magic you once felt building electronics, you are not alone. Aerospace engineers once relied on protractors and books of mathematics tables, and early semiconductor circuits were laid out manually with scalpels and stencils. From computer-aided design to EUV photolithography, new tools opened new frontiers of possibility, letting engineers spend more and more time solving interesting problems instead of doing busywork.
That’s why we built an AI assistant for designing electronics: Flux Copilot. It removes the drudgery for electrical engineers, helps you move faster, and make less mistakes so you can focus on inventing breakthrough products.
When you open Flux, Copilot is waiting for you in the chat. Brainstorming how to approach a particular PCB design? Struggling to fix a stubborn bug? Just ask, and Copilot will respond instantly with suggestions tailored to your project—you can even ask it to wire up schematics or review a design. It's not just a tool; it's your design partner.
Under the hood, Copilot coordinates a team of AI models that collaborate to interpret, research, analyze, and respond to your query. When you ask a question, it remembers your chat history, accounts for project requirements, references relevant datasheets, checks parts availability, and vets comparable options before responding. By drawing on this rich context, Copilot manages its array of specialized models and evaluates results in order to generate the best response to your query.
LLMs add a new layer to the top of the software stack—transforming natural language into a programming language so you can communicate with computers in your native tongue instead of code. So the best way to use Copilot is to treat it like a partner: talking through problems, refining questions, and iterating solutions together. More conversation means more context for it to leverage on your behalf.
Copilot is a tireless deputy dedicated to accelerating your creativity. Hobbyists are using it to build side projects. Entrepreneurs are using it to add new lines of business. Teams at Fortune 100s are using it to inform designs and streamline design reviews. But we’re just getting started.
Imagine you're part of a team that's been tasked with innovating the next generation of wearable health monitors. Stringent design constraints include ultra-low power consumption, medical-grade accuracy, and real-time communication with healthcare providers. A small mistake in component selection could result in a device that fails to meet regulatory standards.
You fire up Flux and initiate a chat with Copilot:
@copilot, we're working on a medical wearable with these specs...
Copilot begins by validating your high-level requirements against current medical standards. Within moments, a list of components that meet your specifications appears on your screen. The AI also generates a basic schematic layout.
Copilot: Based on your specs, here's a rough schematic design with MCU chips, sensors, and power management ICs that fit your criteria. What do you think?
An interactive schematic layout appears on the screen alongside the chat, making it easier for you to visualize the system design. Copilot also estimates the battery life based on the initial schematic and offers to set up notifications for when certain components go on sale or get updated.
Copilot: Looks like our initial Bluetooth choice might consume too much power. How about this low-energy alternative?
The suggestion comes with a recalculated power budget, helping you make an informed decision quickly.
Once the schematic is confirmed, Copilot transitions to creating a basic PCB layout:
Copilot: We're good to go on the schematic. Let's talk PCB layout. I see your mechanical engineering team has constraints for the device enclosure. Shall we coordinate?
You agree, and Copilot generates an initial PCB layout. It also reaches out to your mechanical engineering team to get the constraints for the device enclosure. Within moments, an algorithmically generated 3D enclosure model appears on the screen, designed to perfectly fit your PCB.
Copilot: Here's an auto-generated enclosure that meets the mechanical constraints and fits the PCB layout. How does it look to the team?
After some back-and-forths between your electrical and mechanical teams, facilitated by Copilot, you arrive at a finalized design.
Copilot: Looks like we have a winner! I'll go ahead and run a mock compliance check and notify the firmware team for the final integration.
Fast-forward a few months, and your device is not only meeting but exceeding expectations. Copilot assists in generating the documentation needed for formal compliance checks and eventual mass production.
In the Marvel Cinematic Universe (MCU), Tony Stark uses his trusty AI, J.A.R.V.I.S., to build his Iron Man Armor. When Tony has an idea, J.A.R.V.I.S. is always there—relentlessly competent—to transform that idea into reality. J.A.R.V.I.S. understands what Tony needs and taps the relevant resources to make it happen, extending his agency and increasing the leverage of his decisions.
In many ways, J.A.R.V.I.S. represents the kind of AI that Copilot is evolving toward: a tool that empowers you to make anything you can dream up. But in the movies, Tony is a billionaire and J.A.R.V.I.S. is his and his alone, while Copilot is open to everyone, democratizing access to exclusive domains like electrical engineering. Imagine an MCU where everyone has a J.A.R.V.I.S. working tirelessly on their behalf to improve their lives and world. Thanos wouldn’t stand a chance. That is the kind of abundant future we seek to realize.
One day, Copilot will grok your entire supply chain. It will be able to handle any design task you want to delegate. It will accelerate your creativity by making atoms as malleable as bits. That’s how it will earn the J.A.R.V.I.S. analogy. That’s how it will help you build anything you can possibly imagine, making good on Arthur C. Clarke’s injunction that “any sufficiently advanced technology is indistinguishable from magic.”
So how will you make things better by making better things? We can’t wait to find out.
