Introduction

Huaqiu ERC is an online Electrical Rule Check (ERC) tool designed for PCB schematic design verification. The tool automatically checks schematic circuits for electrical connection errors, including unconnected pins, conflicting outputs, floating inputs, short circuit risks, and other common issues. As a core tool of the Huaqiu open-source hardware platform, ERC supports multiple schematic symbol libraries, can identify component connection logic errors and electrical specification issues, helping users identify and fix problems early in the design process, reduce fabrication failure risks, and improve first-pass success rate.
