* examples: R1/C1 tolerance corners + scipy.signal control cross-checkHEADmainVaino Kauppila3 days1-3/+7
| | | | | | | The RC example now sweeps R1 (+-5%) and C1 (+-10%) extremes, reads the pole off each transient (tau = 1 - 1/e crossing, fc = 1/(2*pi*tau)), overlays the analytic scipy.signal step response per corner, and adds a Bode plot of H(s) = 1/(1 + sRC) with pole/cutoff comparison table.
* examples: runnable RC low-pass demo on a plain netlist (no KiCad)Vaino Kauppila3 days1-5/+18
| | | | | | rc_lp.cir + rc_lp.py: 5 V step into 1k + 100n, prints V(out) at one time constant and writes a plot. README updated for netlist support; results/ output dir ignored.
* Initial commit: kisim — run KiCad schematics in ngspice from PythonVaino Kauppila3 days1-0/+56
Single-file framework: kicad-cli netlist export, netlist edits, ngspice batch runs, results as numpy arrays by schematic name; test-case and corner-sweep helpers. Plus micromamba env (kicad_work), README, gitignore.
