The log said USB D+ was tuned to 78.44 ps. The written board measured 70.56 ps against D-'s 79.25 ps, way past a 0.5 ps skew rule. The winning variant ended its search one connection short of its best state, so the best state went out as snapshotted, never tuned, and the tuning lines in the log came from other variants.
Recurring agent failure issue in TraceMaker (DingoOz)
What engineers report
A recurring agent failure problem in TraceMaker (DingoOz) that mostly hits the electrical engineer.
Failure pattern: agent / failure
Analyst note
From the Grok pain-radar digests, Nov 8-9 2026 (Nov 8 8:41 AM ET through Nov 9 6:41 AM ET digests plus the Haitch editions). Verified live 2026-11-09: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

Evidence
More recurring errors in TraceMaker (DingoOz)
- On a 1,194-connection four-layer PoE board, GND and +54V zones were written without fills so the router saw no plane and laid 1,773 mm of tracks instead (some on the other net's plane layer), and it ignored JLCPCB's 0.254 mm hole-to-copper rule. KiCad caught 14 errors.ECAD · impact 74
- --si-rules marked the unused D+/D- pins on a charge-only USB-C socket as four critical USB nets, each a single-pad net. Fix skips nets with fewer than two pads.ECAD · impact 66
- A JLCPCB conditional rule made pair routing 55 percent slower, stuck near 116 connections.ECAD · impact 66
- A third-party router's own DRC reported 22,362 clearance problems on a board where KiCad reported none, and reaching parity took matching KiCad 10.0.6 rule by rule, 239 of 239.ECAD · impact 66
- Adds repair windows because a partly routed board left pins walled in and the only other option was a full reroute.ECAD · impact 66
- KiCad's physical_clearance rule forbids vias in their own net's pads. "TraceMaker did not evaluate the rule anywhere, and its routes broke it," giving 25 via_not_in_pad errors on a test board. Now 0. Zone fills still don't apply the rule.ECAD · impact 66
