Development status

Updated 2026-11-01. This page describes the source published with the RustEDA development update. Use the superproject’s exact gitlinks and the repository lockfile when reproducing a run.

Adaptive simulation and bounded device kernels

The simulator source includes adaptive transient integration and breakpoint handling, strict SPICE parsing with expressions/includes and explicit resource limits, extended diode/level-1 MOS and controlled-source coverage, and adjoint parameter sensitivities. Batched FP64 DC has a deterministic CPU reference and an optional CUDA kernel with explicit fallback for unsupported/nonconverged cases.

The retained ngspice-47 accuracy suite reports 857 passing, 16 documented gaps, 77 informational and one unverified case out of 951, with no failing cases; 400 random decks and 200 hostile inputs are recorded separately. These are accuracy/robustness results from the existing campaign, not new performance measurements made for this publication.

RustSpice is not timed in Ibex RTL-to-GDS. It has no Ibex speedup claim. BJT, JFET, MESFET and MOS levels above 1 remain unsupported. The benchmark command writes its report outside published documentation unless an output is explicit.
