Importing Copper from Reference Design

import the copper from the reference design.

Thought for 18 sec

I’ll compare the imported reference block against its source, reconcile the matching copper, then run a board check to verify the result.

The preview found 26 traces and 4 vias available; copper tied to D1 and four changed nets will be safely excluded rather than forcing mismatched routing. I’m checking that placement difference before importing the compatible remainder.

Imported the compatible copper from the USB-C reference block: 26 trace segments, 4 vias, 1 keepout, and 7 rulesets. Verified the copper exists in the layout with no reported overlap, floating-copper, dangling-trace, or invalid-layer issues.

Open items

D1 and nets Net 86, Net 103, VUSB, and VBUS were safely excluded because they differ from the reference.
Seven airwires remain, primarily on VBUS and the ORing path.

Suggested next steps

Manually route the excluded power/ESD nets.
Resolve the remaining airwires.
Run a full DRC after routing.

Route, verify, run DRC

Route excluded nets

Clear all airwires

Reference Block Plan

USB-C power entry and battery ORing

Classification: Exact
Matched reference: flux-reference-design/usb-c-2p0-power-entry-and-esd-protection-reference-design
Decision: Import the complete standalone reference as one functional block.
Fit: USB-C 2.0 receptacle, 5.1 kΩ CC sink resistors, USB data ESD protection, VBUS/VBAT inputs, and Schottky/P-channel MOSFET power-path ORing to PP5V0.
Placement: Preserve the reference schematic and PCB component arrangement; defer copper reconciliation until final placement.
Import status: Complete. Imported as functional group USB-C Battery ORing.
Deferred copper block ID: 363aa35a-e192-44c5-903e-70d9bddf71f0
Verification: 18 schematic objects, 16 nets, and 10 PCB footprints imported. ERC has only expected warnings for unused SBU pins and the two protected USB data outputs awaiting downstream connection.
