Electrical Schematic Capture and Live BOM Sync for PCB Engineers

TLDR

Hardware engineers and electronics designers who need to capture schematics often find traditional desktop EDA tools (like Altium, OrCAD, or KiCad) too heavy for quick sub-circuit sketches and BOM creation. GINEXYS Schema Editor runs in your browser, featuring standard electrical symbol libraries, net trace verification, 90°/45° Manhattan wire routing, and automatic Bill of Materials (BOM) generation that syncs live to Table Formatter over local IPC.

The Persona & The Pain Point

You design PCB layouts, develop embedded hardware, or manage electronic component procurement.

When you want to sketch a quick sensor sub-circuit, review an op-amp filter idea, or draft a schematic for documentation, opening a heavy desktop EDA suite is overkill. Furthermore, compiling a Bill of Materials (BOM) requires exporting raw CSV files and manually aggregating part quantities in Excel, leading to procurement mistakes when component values are changed on the schematic.

The Workflow in Practice

1. Open Electrical Mode: Launch Schema Editor and switch to Electrical Mode (or load /tools/schema-editor/electrical/).
2. Place Symbols & Enter Engineering Units: Drag resistors, capacitors, and ICs onto the canvas. Type shorthand engineering values (4k7, 100n, 10u) that automatically validate against component types.
3. Route Manhattan Net Wires: Connect terminal pins with 90° orthogonal wires that automatically steer around intermediate components.
4. Verify Connectivity with Trace Mode: Press T to enter Trace Mode. Click any pin or wire to illuminate the entire connected signal net in bright green, verifying that power and signal rails are intact.
5. Generate Live BOM over IPC: Click Generate BOM. Schema Editor aggregates component counts and footprints, automatically launching Table Formatter over local IPC with your live parts list ready for pricing.
