Importing Copper from 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.
Worked for 1 min 15 sec
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.
Worked for 2 mins 26 sec
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
Verify power integrity
Run full DRC
