Capture method = SKiDL per decision. circuits/stage1_input.py defines the balanced line receiver + per-leg protection (DC-block film cap, series R, bias R, clamp diodes to the rails) and emits a KiCad netlist. ERC: 0 errors (2 expected warnings -- AIN_HOT/COLD reach only one pin until the interconnect block exists). Container: env vars point SKiDL/KiCad at the symbol/footprint libs. VERIFY-before-layout flagged in-file: exact THAT124x gain suffix, its SO-8 pin numbers, clamp-diode orientation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Reproducible EDA toolchain for the PM_K-1 core board.
|
|
#
|
|
# Why this exists: the system KiCad is 7.0 (no CLI ERC). This pins a known,
|
|
# rebuildable environment so the design can be checked/simulated identically
|
|
# years from now — fitting for a device meant to outlive its tools.
|
|
#
|
|
# KiCad 9 -> schematic capture, CLI ERC/DRC, netlist/PDF/Gerber export
|
|
# ngspice -> SPICE simulation of the analog audio circuits
|
|
# python3 -> scripting / BOM / skidl-style helpers
|
|
#
|
|
# Build/run via ../eda/run.sh (or: podman build -t pmk1-eda:9.0 .)
