1.0.78: 1.0.78: SPICE simulation from a KiCad schematic, headless, through the ngspice KiCad installs.

Colby Knox ·25732ee228 ·12d ago ·parent 2181f14

- **kicad_simulate (new, wiki #89):** runs a sheet through ngspice, the simulator KiCad itself uses. - Analyses: transient, AC, DC sweep or operating point, given in the call or carried by the schematic. - Probes are node voltages V(/NET) and source currents I(V1). Each comes back downsampled with its first, last, min and max (AC as dB and phase), and as a CSV file. - ngspice runs in a child process, so a circuit that crashes it never takes the bridge down, and a failed analysis returns ngspice's own message. - Checked: an RC low-pass of 1k and 100n is -2.99 dB and -44.9 degrees at 1.58 kHz, and passes 0.85 of a 1 kHz sine. - **kicad_export_spice (new):** KiCad's own SPICE netlist of a sheet, with its elements, its analyses and the model files it includes. - **Engine:** adom-eda-checks 0.10.4 (standard 0.13.4): plan_route keeps a pour holding the route's own end pad out of avoidPours, echoes its pour settings, and smooths grid staircases into straight and 45-degree segments.
