Learn to perform Electrical Rules Check (ERC) and Design Rule Check (DRC) in KiCad 9.0 through this 10-minute beginner tutorial. Master the essential validation processes that ensure your schematic designs and PCB layouts are error-free and ready for fabrication. Discover how to execute ERC checks to validate electrical connections and identify common schematic errors including input power pins not driven by output power pins, symbols or wires positioned off the connection grid, duplicate net names, unconnected pins, missing symbol libraries, outdated symbols, and duplicate items. Explore DRC functionality to verify your PCB layout meets manufacturing requirements, addressing issues such as hole sizes outside acceptable ranges, incorrect text heights, silkscreen overlaps, and outdated footprints. Understand how to enable previously ignored tests in both ERC and DRC to catch additional potential problems. Learn to import manufacturer-specific DRC templates to ensure your designs comply with fabrication house requirements, making your PCB designs production-ready and reducing costly manufacturing errors.
