Synchronize schematic and PCB

Before you start

• A saved schematic
• A footprint assigned to every component that goes on the board

Applies to: Resin web app

Follow the steps

1. 1

   Save the schematic

   Press Ctrl+S (Cmd+S) in the Schematics tab. The push reads the saved file, so unsaved edits are not included.

   Schematics tab
   

   Expected result

   The save indicator shows the schematic is saved.

2. 2

   Open Push to PCB

   In the schematic toolbar open Project > Sync and choose Push to PCB. The Update PCB from schematic dialog computes the difference between the schematic and the board. If the project has no board yet, the dialog says so; applying will create a new board file.

   Schematics > Project > Sync > Push to PCB
   

   Expected result

   The dialog lists the changes, or says there are none.

3. 3

   Fix missing footprints

   If the dialog reports N component(s) have no footprint, those parts cannot be placed. Use Fix on each row to link a library footprint, import one, or generate one with AI, then reopen the dialog.

   Update PCB from schematic > Fix
   

   Expected result

   No component is listed without a footprint.

4. 4

   Review the change list

   Changes are grouped by category: components to add, update, or remove, and net changes. Every row is selected by default; untick a row to leave it out of this push. A removal means a footprint on the board has no matching schematic symbol. Use Report to download the list.

   Update PCB from schematic
   

   Expected result

   Every selected row is a change you expect.

5. 5

   Apply

   Choose Apply to PCB, then Confirm apply N. New footprints are placed on the board for you to move; existing footprints keep their position. Open the PCB tab to see the result.

   Update PCB from schematic > Apply to PCB
   

   Expected result

   The PCB tab's Design Sync indicator reads schematic and PCB match.

6. 6

   Place the new footprints and re-run DRC

   Move each new footprint into place; new parts arrive with unrouted connections shown as ratsnest lines. Run DRC afterwards (see Run and triage DRC).

   PCB tab
   

   Expected result

   No new footprint is left where it landed, and DRC has been re-run.

Check your result

• Schematic saved
• No missing footprints
• Change list reviewed
• Applied once
• Design Sync shows match
• New footprints placed
• DRC re-run
