Rolling Your Own Circuit Simulator
summary
A compact pipeline shows a working circuit simulator built from parts rather than promises: it converts nets into a modified nodal analysis system using conventional stamping components, fixes a singular C with Gaussian elimination and reordering, then uses Eigen for the matrix work and Boost.Odeint to integrate the resulting ODEs, reproducing the expected resistor‑capacitor‑inductor transient with only small numeric artifacts and source code available on GitHub.
