Fixing Missing Routed Traces

Figuring out Flux steps.

Reading docs about How do I fix an Airwires review error in Flux PCB layout? The review flagged missing routed traces between pads in a net. I need the practical steps in the UI to resolve it..

Running design review.

Analyzing the PCB layout.

Analyzing the schematic.

Reading docs about PCB Airwires review missing routed traces between pads. How does a user resolve unrouted connections in Flux layout and verify the review clears?.

Reading docs about In Flux PCB layout, what documentation explains resolving unrouted nets or missing traces after DRC/Airwires review, especially using auto-layout or layout updates?.

This specific error means the BOOT net is connected in the schematic, but not yet routed in the PCB.
I checked your project data: C7 P1 and U1 BOOT are correctly on the same BOOT net in the schematic, so this is a layout routing issue, not a schematic connectivity issue. I also see the Airwires review currently has 78 unrouted-pad errors total, so this is one of several remaining PCB routes. Using the project data tools this way is the right workflow for diagnosing issues like this
The most relevant Flux doc entry I found says:
"Flux’s layout rules do a great job of eliminating unnecessary mistakes, but certain types of violations require additional checking. Such violations include overlapping traces, unrouted nets, missing footprints, etc.
In Flux, DRCs run in real-time, and their results can be accessed from the messages menu."

And for Auto-Layout, the doc says:
"Only new traces are generated to complete the remaining unrouted connections (airwires)"

What to do:
  • In PCB view, select the flagged pads on C7 and U1.
  • Route a copper trace between C7:P1 and U1:BOOT.
  • Then re-check the review; DRC updates in real time.
One project-specific note:
  • The BOOT capacitor C7 is currently placed quite far from U1, so even after routing, you’ll probably want that connection kept short.
If you want, I can also help you identify the other unrouted airwires after this one.
