No Connects
No-connect markers indicate that a pin is intentionally left unconnected.
Use them when a symbol pin is not used in your design, but you want to make that explicit to anyone reading the schematic and to the design rules checker.
What no-connects are for
- document intentional unused pins,
- reduce ambiguity during review,
- avoid DRC warnings/errors for pins left open by design.
Typical examples include unused logic inputs, spare op-amp channels, or unused connector pins.
How to place no-connects
- Select the No Connect tool.
- Place the marker directly on the unused pin (or intended open point).
- Repeat for each intentionally unconnected pin.
No-connects are simple markers: they can be moved or deleted after placement, but are not otherwise edited.
Best practices
- Use no-connects consistently on all intentionally open pins.
- Do not place no-connects on pins that should be wired later.
-
Run DRC after major edits to catch newly unconnected pins.
