Bulk Autorouting


DRC is currently failing only on Airwires: 173 errors — those are unrouted connections, not a blocker to autorouting; they are what the autorouter should consume. I did not see blocking DRC categories like missing footprints, invalid layers, components outside board, body overlaps, pad-access clearance issues, dangling traces, or copper overlaps in the returned checks.
Open items:
  • Bulk autorouting should be possible from a DRC standpoint.
  • This is a power distribution board, so high-current rails may still need manual trace/polygon sizing after autoroute.
  • The active user rule set is Auto-Layout: Universal Keepout, enabled.
Suggested next steps:
  1. Run bulk autoroute on the 173 airwires.
  2. Re-run DRC afterward for shorts/overlaps/under-connected vias.
  3. Manually review and widen high-current VIN/OUT/SW paths and add copper pours where needed.
I’ll bulk autoroute the current airwires, re-run DRC, then inspect the routed power paths for any high-current segments that should be manually widened or converted to pours.
I’m checking routing prerequisites first; the bulk autoroute backend isn’t exposed in my available project tools, so I’ll verify whether I can still proceed with available routing operations or need to hand this back to the UI action.
I couldn’t run the bulk autorouter from my available project tools; only targeted pad-to-pad routing is exposed here. I did re-run DRC: the board still has 173 airwire errors and no returned copper-overlap/dangling/under-connected-via errors; the high-current nets to manually review after UI autoroute are 24V_RAW, 24V_BUS, 5V_BULK, 15V_PRE/15V_LASER, 12V_POS_RAW, 12V_NEG_RAW, 15V_ISO_POS/NEG, U2_SW, U5_SW, and U7_SW.
Open items:
  • Bulk autoroute still needs to be launched from the Flux UI.
  • After autoroute, those power and switch-node nets should be widened/replaced with pours where current or ripple is significant.
Suggested next steps:
  1. Run bulk autoroute in the PCB UI.
  2. Ask me to re-run DRC immediately after it completes.
  3. Ask me to inspect/widen the high-current nets manually after the autoroute result exists.
