D52 — tracemaker-place defaults to --component-rules soft¶
Decision¶
tracemaker-place defaults to --component-rules soft (proximity pseudo-nets for crystals, load caps, ESD parts, regulator caps and generalised decoupling; objective-only, two-stage in full mode per D43); routing's default stays off
Alternatives¶
Keep off (or report) until decap distances also improve
Reason¶
Placed tiers B and C (70 boards, rules off vs soft side by side): clean pass 28 → 28 and 18 → 18, routed 5,163 → 5,156 and 9,538 → 9,539; XTAL-01 median 6.54 → 5.57 mm, load caps 3.11 → 2.81 mm, decaps 3.17 → 3.17 mm (losses traced to the router keeping a different candidate). Full mode, 23 boards × 3 seeds (D43): crystal and load caps better, decaps equal. No routing cost, a measured gain for crystals; doc 15 §14.3
