Cherry Blossom

Product Introduction

1. Definition: Cherry Blossom is an AI-first Electronic Design Automation (EDA) software-as-a-service (SaaS) platform. It is a browser-based PCB design tool that uses frontier large language models (LLMs) to convert natural language descriptions into complete, editable electronic circuit designs.
2. Core Value Proposition: It exists to dramatically accelerate the PCB design workflow by eliminating the initial blank-canvas barrier. Its primary value is enabling engineers, makers, and hardware startups to go from a functional idea to a manufacturable board design in minutes, not days, while integrating automated design rule checks to prevent costly fabrication errors.

Main Features

1. Prompt-to-PCB Schematic Generation: Users describe a circuit's function, components, power requirements, and behavior in plain English. The AI interprets this prompt, selects appropriate components (like ESP32-S3 MCUs or DRV8313 gate drivers), and generates a complete, logically correct schematic. This schematic is immediately editable in the built-in visual editor, allowing for manual refinement.
2. AI-Powered Verification Gate: This is a core technical feature. Before any design is finalized, the system runs automated preflight checks. It validates component footprints (e.g., flagging a mismatch between a SOT-23-6 symbol and an 0805 layout footprint), power integrity (e.g., identifying missing 100nF decoupling capacitors on an MCU's VDD rail), and manufacturability rules. This surfaces potential failures before the board is sent to a fab house like JLCPCB or OSH Park.
3. Open Format Export & Integration: Cherry Blossom avoids vendor lock-in by exporting industry-standard, editable files. Users can export complete KiCad projects (.kicad_sch, .kicad_pcb) for further routing or simulation. It also directly exports fabrication-ready Gerber/drill files and Bill of Materials (BOM) tailored for manufacturers like JLCPCB, OSH Park, and MacroFab, with profiles that check against their specific design rules.

Problems Solved

1. Pain Point: The high time investment and specialized expertise required to start a new PCB design from scratch, especially for complex circuits like BLDC motor controllers or USB-C Power Delivery triggers. It also addresses the costly, post-fabrication discovery of design errors (e.g., footprint mismatches, insufficient decoupling) that lead to re-spins, project delays, and financial waste.
2. Target Audience: Hardware startups looking to prototype faster, freelance electronics engineers managing multiple client projects, makers and hobbyists transitioning from breadboards to custom PCBs, and even students or educators learning PCB design fundamentals.
3. Use Cases: Rapid prototyping of IoT sensor nodes based on ESP32-S3; designing custom motor driver boards for robotics; creating one-off USB-C PD trigger boards for lab equipment; developing open-source hardware where the design process can be documented and shared via prompts.

Unique Advantages

1. Differentiation: Unlike traditional EDA tools (KiCad, Altium) which require manual component placement and routing from zero, Cherry Blossom provides a generative starting point. Unlike other AI-assisted tools, it deeply integrates verification during the AI design process, not as an afterthought. It also provides built-in AI credits, removing the need for users to manage their own API keys with model providers.
2. Key Innovation: The "Design Block" architecture and the "Verification Gate." The AI constructs designs using pre-verified functional blocks (e.g., "Power input," "3V3 rail," "MCU + USB"). More importantly, every AI-generated edit is checked against a rule engine before being committed to the design, ensuring the output is not just logically plausible but also manufacturable. This combines generative AI with real-time electronic design rule checking (DRC).

Frequently Asked Questions (FAQ)

1. How does Cherry Blossom's AI PCB design work? Cherry Blossom uses frontier large language models to interpret your natural language description of a circuit's function. It maps your requirements to electronic components, creates their logical connections in a schematic, assigns physical footprints for the PCB layout, and runs automated checks for errors before presenting you with an editable, fab-ready design in your browser.
2. Can I edit the AI-generated PCB design from Cherry Blossom? Yes, absolutely. The core output is an editable schematic and PCB layout within the Cherry Blossom browser editor. You can manually add, remove, or modify components and connections. Furthermore, you can export the entire project to KiCad, the leading open-source EDA tool, for advanced routing, simulation, or final touches.
3. Is my circuit board IP safe with an AI PCB design tool like Cherry Blossom? Cherry Blossom employs a local-first, privacy-focused architecture. Your design projects are stored in your browser's local storage or in exported files. Only the minimal context necessary to process a specific AI action (like a prompt or a fix) is sent to their servers, and they state that no API keys to external model providers are required from the user, centralizing data handling.
4. What manufacturing files can I export from Cherry Blossom for PCB fabrication? You can export industry-standard Gerber files (RS-274X) and Excellon drill files, which are universally accepted by PCB fabs like JLCPCB and OSH Park. It also exports a Bill of Materials (BOM) and placement files for assembly services. The tool includes specific manufacturing profiles to pre-check your design against the rules of popular fabs.
5. What is the cost of using Cherry Blossom for AI PCB design? Cherry Blossom operates on a credit model for AI processing. Notably, they provide initial AI credits for users to try the platform. This differs from a pure subscription or seat-based model, as your usage is tied to the computational cost of the AI generation and verification tasks you perform.
