KEMI Tools

Circuit Size Check

Drop a KiCad (.kicad_sch) or Eagle (.sch) schematic — or a KiCad/Protel/PADS netlist — and review the part makeup and design size instantly. Power symbols (GND/VCC) are excluded automatically, and everything runs in your browser.

FAQ

Why is approval required?

This is a working design-review tool, so we confirm who is using it before opening it. Sign in with Google and send an approval request; KEMI will review and approve it.

What about Altium .SchDoc?

Altium schematics are a binary format that can't be parsed in the browser. Upload them to the PCB layout quote and the server reads the original file directly.

It says power symbols were excluded.

GND/VCC-style power symbols aren't mounted parts, so they're excluded automatically.

I get a sub-sheet warning.

Hierarchical KiCad designs span multiple sheet files. Drop all related .kicad_sch files together and they'll be summed.
