USB Audio Interface Design

I’ll cancel the corrupted routing job, remove only the orphaned routing vias/traces while preserving placement and valid footprint copper, verify DRC/readiness, then start a fresh full-board routing job.
The canceled job left orphaned “Smart Via” and trace nodes behind. I’m clearing all routed trace/via primitives from the failed attempt—logical nets, footprints, planes, and placement remain intact—then I’ll verify the board is back to a clean unrouted state.
The direct bulk cleanup is timing out because the failed job created hundreds of zero-position via artifacts. I’m handing off one bounded cleanup pass to remove all standalone route primitives while preserving the board, footprints, locks, and netlist, then I’ll recheck readiness.
Canceled the corrupted routing job and attempted bulk cleanup, but hundreds of orphaned zero-position via/trace artifacts remain because the cleanup operations timed out. ACUs are now unavailable, so readiness and the fresh routing job could not be started.
Remaining:
  • Delete all standalone routing traces/vias while preserving footprints, planes, placement, and nets.
  • Confirm zero invalid-layer, floating-copper, and dangling-trace errors.
  • Rerun route readiness.
  • Start a fresh full-board routing job.
