ERC
AKA: electrical rule check
Electrical Rule Check — automated verification of a schematic for connectivity and pin-usage errors.
ERC scans a schematic for electrical problems: unconnected pins, two outputs driving the same net, a power pin with no source, conflicting pin types. It catches mistakes early — before they become layout headaches or bricked prototypes.
ERC runs on the schematic only. Its layout-side counterpart is DRC, the Design Rule Check.
Designing a board that uses erc?
PCBEditor turns a plain-English description into a verified schematic — then handles placement, routing, and export to Gerber or KiCad.
