DRC doesnt catch unconnected nets

Created: 25.03.2021 | Updated: 12.08.2021

I have a PCB design in which the DRC doesn't catch unconnected nets, although the check is enabled in the design rules.

Starting in Version: 18.0
Up to Version: Current

Solution Details

There are various ways to detect unrouted nets:

1. Use Tools ► Design Rule Check to select the "Rules To Check" tab in the left pane, then check the box in the "Batch" column for the "Un-Routed Net" row near the bottom. Click the button in the lower left corner to "Run Design Rule Check...". Note that this check is not available online.  After running the DRC, error markers will show on your PCB.  You can use Tools ► Reset Error Markers to remove them.

2. Reports ► Board Information  check box for Routing InformationReport button

3. PCB Filter panel ► Query: IsConnection will show all airwires (Connection Lines) on the PCB.
