Example output

Everything here was produced by this toolkit and is committed so the README can show real output rather than describe it. Regenerate any of it with the commands below; nothing is hand-edited beyond downscaling for the repository.

Open Air Max (KiCad demo project)

openair-max-*.jpg are derived from the Open Air Max demo project by AirGradient, which ships with KiCad in /usr/share/kicad/demos/openair-max and is licensed CC BY-SA 4.0. These rendered images are adaptations of that work and are therefore also CC BY-SA 4.0 — unlike the rest of this repository, which is Apache-2.0.

File	What it is
`openair-max-layers.jpg`	the board contact sheet: 6 composite views, 4 copper layers, 3 renders
`openair-max-3d.jpg`	the isometric 3D render
`openair-max-schematic.jpg`	sheet 1 of 3 of the schematic
`openair-max-crosstalk.jpg`	`eda pcb crosstalk` — the ten worst coupled runs struck through in magenta where they sit, numbered by each pair’s `index` in the JSON. Pair 1 is the I2C pair: `/SCL` beside `/SDA` for 65.5 mm at a 0.198 mm gap on `F.Cu`, which the solver prices at 94 mV of near-end noise on a 3.3 V, 1 ns edge — the number the `emc.parallel_run` warning could only gesture at, at the place a reviewer can walk to

Thermal map and heating curve (buck-5v example)

buck-5v-thermal.jpg and buck-5v-heating.jpg are eda pcb thermal over examples/buck-5v/reviewed with the LM2596 stated at 1.5 W: the steady map marks the hottest cell (28.8 K over ambient, at x=160.3 y=70.3 on the board), and the curve is --transient 300 from power-on — 63% of the steady rise at 41 s, 95% of it reached by five minutes. The transient’s energy books balance to the solver’s own stopping tolerance, which the JSON carries as transient.balance.residual.

File	What it is
`buck-5v-thermal.jpg`	the steady temperature map, hotspot marked
`buck-5v-heating.jpg`	the heating curve, the 63% clock marked where it landed

./bin/eda.sh pcb thermal examples/buck-5v/reviewed --power U1=1.5   --transient 300 -o build/thermal

Revision diff

diff-schematic.jpg and diff-board.jpg are eda diff run over two revisions of the test fixture, with C2 moved on the sheet, R1 moved on the board and its value changed from 10k to 4k7. Red is what the old revision had and the new one does not; green is the other way round, so a part that moved is both. Both are the zoomed detail crop the command writes alongside the full page — on an A4 sheet the change is a few hundred pixels of two megapixels.

File	What it is
`diff-schematic.jpg`	C2 red where it was, green where it is now; R1’s value change marked
`diff-board.jpg`	the same R1 move on the front copper

git worktree add /tmp/base <ref>
./bin/eda.sh diff /tmp/base/hardware hardware/ -o build/diff

Both come from this repository’s own fixture, so they are Apache-2.0 like the rest of it.

RC low-pass reference circuit

rc-lowpass-*.jpg come from tests/fixtures/spice/rc_lowpass.cir, which is part of this repository (Apache-2.0). Its corner frequency is 1/(2πRC) = 1000 Hz by construction, which is what the test-suite checks against.
