Knowit 54f0173947 tools/epro2/kicad: fix two structural ERC bugs — wire_dangling -88%, pin_not_connected -52%
Bisect found two semantics mismatches between EPRO2 and KiCad that cause
the 850 real-connectivity ERC violations on the ESP-VoCat ref project:

1. sym_writer was emitting lib coords without negating Y, but KiCad lib
   uses Y-up and re-flips Y on placement (Y-down schematic). So vertically
   arranged pins ended up at Y-mirrored absolute positions and wires that
   reach the geometric pin tip in EPRO2 missed the rendered pin tip in
   KiCad. Fix: lib_y = -epro2_y, lib_rot = (360 - rot) % 360 for pin/text.

2. sch_writer was treating each LINE as an isolated wire — but EPRO2
   binds segments into nets by NAME (WIRE.NET attr), not just geometry.
   Multi-segment nets like GND/VBUS show up as N disconnected stubs to
   KiCad. Fix: per-LINE, look up lineGroup → WIRE → NET attr and emit a
   `(label "<NET>")` at the LINE's start. Same-named labels on distinct
   physical wires is how KiCad's ERC recognizes a multi-segment net.

ESP-VoCat 9 sheets:
  wire_dangling           444 →  52  (-88%)
  pin_not_connected       406 → 196  (-52%)
  real connectivity total 850 → 248  (-71%)

Why we did NOT round to grid (the obvious-looking fix): EPRO2 places
some pins on a 10-mil pitch (e.g. magnetic socket); rounding to KiCad's
default 50-mil ERC grid would collapse those pins. The 248 residual is
fundamentally cross-sheet — single-sheet ERC can't see a net's other
endpoints on sibling sheets — and is a Phase-3 (hierarchical sheet)
problem, not a per-sheet one.

41 → 46 unit tests pass.

FacereDataset

Facere 专有模型训练与硬件设计知识库提供数据支撑的开源硬件设计数据集。

目标

采集、清洗、结构化互联网公开可用的硬件设计资产原理图、PCB、BOM、Gerber、3D 模型、固件、文档),输出:

  1. 训练数据集:可直接喂给 LLM / 多模态模型做预训练、SFT、RAG 的结构化语料。
  2. 检索型知识库:按元器件、拓扑、应用领域可查的设计参考库。
  3. 派生产物元件封装库、常见子电路模板、BOM 成本曲线等。
