AI-Based Electrical Schematic Symbol Automation Tool

Who Should Apply

Please apply only if you have direct experience in electrical symbol creation, library development, or related automation systems. This project requires more than general coding ability. Preference will be given to freelancers who can demonstrate a clear understanding of the requirement and prior implementation experience in this area.

Project Overview

I am looking for an experienced freelancer to develop an AI-assisted electrical schematic symbol automation tool with a strong focus on accuracy, structured symbol generation, editing flexibility, and multi-EDA export support.

Core Concept

The main concept of this project is as follows:

A user will open a component datasheet from a website, PDF, browser, or any other source.
The user should be able to capture the pin diagram or pinout section using a dedicated global hotkey.
Once the screenshot is taken, the tool should automatically begin generating the corresponding IC schematic symbol.

This workflow should be fast, practical, and convenient, without requiring repeated manual import steps.

Global Hotkey Capture Requirement

This is one of the main requirements of the project:

The screenshot capture must work through a dedicated global system-wide hotkey.
The hotkey should work from anywhere on the PC.
Once triggered, it should allow the user to capture the required datasheet pinout area.
After capture, the tool should automatically start the symbol creation process.

Automatic Symbol Generation Logic

The tool should not generate symbols randomly. It must follow strict symbol creation rules and structured placement logic.

Pin Placement Rules

Initially, the generated IC symbol should support pin placement on the left and right sides only.
Pin arrangement must be clean, readable, and grouped properly by function.
Pins must not be placed in a random or unorganized manner.

Functional Grouping Expectations

For example:

Power pins such as VCC, VDD, AVCC, VBAT, and similar pins should be placed in the top-left area.
Ground pins such as GND, AGND, DGND, PGND, and similar pins should be placed in the bottom-right area.
Communication or grouped signals such as SPI, I2C, UART, GPIO, input, output, and control pins should remain grouped together in a logical and continuous arrangement.
Related signal families must stay together and should not be split randomly.

Symbol Standard Compliance

Active-low pins must be identified properly and shown using the correct notation, such as overbar or inversion indication.
The full symbol creation flow should follow professional schematic symbol creation practices.

Mandatory Accuracy Requirement

This is a critical requirement.

The generated symbol must maintain 100 percent accuracy.
Pin number and pin name must match the datasheet exactly.
Any mismatch in pin number, pin name, or grouping is unacceptable.
If the generated symbol contains mismatched data, it will not be accepted.

Automatic Electrical Type Assignment

The tool must also automatically detect and assign the correct pin electrical types.

Examples include:

Input
Output
Bidirectional
Passive
Power Input
Power Output
Open Collector
Open Emitter
Tri-state
Clock
Active Low
No Connect
Other equivalent types supported by the destination EDA tools

Manual Editing Option

If required, the user must be able to click on a pin, open its properties, and edit the electrical type manually.

Proper Visual Pin Identification

The generated symbol should also reflect correct visual identification wherever applicable.

Examples:

Input pin representation should follow the target symbol standard.
Output pin representation should match the expected notation.
Clock pins should show the proper clock indicator.
Bidirectional pins should use the correct bidirectional representation.
Active-low pins should show the inversion or overbar indication.
Similar standard symbol-level markings should be supported wherever applicable.

Cross-Tool Electrical Type Mapping

Another very important requirement is that electrical pin types must map correctly across all supported EDA export formats.

For example:

If exported to Altium, the pin type should match Altium’s supported type system.
The same should apply to OrCAD, KiCad, Eagle, Expedition, and similar tools.
Electrical meaning must not be lost during export or conversion.

Built-In Symbol and Library Features

The tool should include a built-in library of default generic and discrete symbols, such as:

Resistor
Capacitor
Inductor
Transformer
Diode
Transistor
Relay
Connector
Fuse
Switch
Crystal
Op-amp
Generic IC blocks
Other commonly used default symbols

The tool should also provide:

Option to manually create custom symbols
Option to edit automatically generated symbols
Proper symbol library creation and management
Save, classify, and organize symbols properly
Reuse symbol families and templates where needed

Editing and User Experience Requirements

The tool must provide a practical and smooth editing experience with features such as:

Clean and accurate symbol editor window
Easy pin editing
Pin name, pin number, pin type, and visibility controls
Electrical type editing
Pin length adjustment
Grid snapping
Rotation and mirror options
Origin or reference point control
Line, arc, box, and circle drawing tools
Undo and redo
Zoom in and zoom out
Alignment and spacing tools
Symbol preview before save or export

Smart Functional Requirements

The tool should also include smart automation features such as:

OCR or image interpretation from datasheet screenshots
Automatic pin name recognition
Automatic pin number extraction
Automatic functional grouping suggestion
Family-based symbol generation logic
Duplicate pin handling
Multi-unit IC support where applicable
Rule-based validation for generated symbols

Template-based generation for common IC categories such as:

Microcontrollers
Memory ICs
Analog ICs
Power ICs
Logic ICs
Connectors

Export Requirements

The final generated symbols or libraries should support export to multiple EDA tools such as:

Altium
OrCAD
KiCad
Eagle
Expedition
Other similar tools where possible

UI and Application Requirements

The application should also include:

User profile creation and management
Project save and load support
Light mode
Dark mode
System default mode
Modern and user-friendly interface
Fast workflow for bulk symbol generation
Search and filter for saved symbols
Category-based library view

Technology Flexibility

There is no strict restriction on the development language, framework, file structure, or software platform.
The developer may use any suitable programming language, framework, architecture, or technology stack.
There is no language preference from our side.
The main priority is achieving the required functionality, workflow, and output quality correctly.

Important Requirement Compliance and Payment Condition

Please read this carefully. These requirements are mandatory and not optional.

All listed requirements and workflow expectations must be implemented properly.
The expected functionality, logic, automation flow, and output quality must be satisfied fully.
If the tool does not achieve the required result as expected, the project will not be considered complete.
In such a case, payment will not be released.
Payment will be released only after the requested requirements are fully achieved and verified.

Scope Clarification

Please note that these are the initial core requirements only.

Additional minor refinements, fine-tuning requirements, small workflow adjustments, UI corrections, and add-on convenience features may be shared later during the development process.
These smaller updates may not be explicitly listed here at this stage, but they are considered part of the expected fine-tuning process.

Final Expectation

The goal is to develop a professional, structured, accurate, and practical symbol automation tool that can significantly reduce manual effort in schematic symbol creation while maintaining industry-standard quality and export compatibility across multiple EDA platforms.
