NeuroSPICE: When Circuits Stop Ticking and Start Thinking
Opening — Why this matters now Circuit simulation has always been an exercise in controlled compromise. We discretize time, linearize nonlinearity, and hope the numerical solver behaves. SPICE has done this extraordinarily well for decades—but it was built for an era where devices were mostly electrical, mostly local, and mostly cooperative. That era is ending. Ferroelectrics, photonics, thermal coupling in 3D ICs, and other strongly nonlinear or multi-physics effects are turning compact modeling into a brittle art. Against this backdrop, NeuroSPICE proposes something mildly heretical: stop stepping through time altogether. ...
