pyNgSpice

Joe DiPrima 6eeaaa7ca7 Add pyngspice Python bindings with targeted capacitor probing Initial commit of the pyngspice layer on top of ngspice: - pybind11 C++ bindings (src/cpp/, src/bindings/) - Python package with SpiceRunner interface, netlist preprocessor - Targeted capacitor probing via .save i(C_name) directives for fast simulation when only specific cap currents are needed - Build system (CMakeLists.txt, pyproject.toml, build_mingw.py) - Test suite with 70 tests covering all preprocessor features - Examples, winflexbison tooling, CLAUDE.md project docs Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>		1 month ago

TransImpedanceAmp	Some hints how to use this file	8 years ago
TransmissionLines	Better visibility of the results	3 years ago
cider	Enable CIDER with KLU for DC, OP, and TRAN analyses. Small signal AC analysis is not yet supported for CIDER complex valued device KLU matrices. The examples/cider testcases produce printed simulation result values which have slight differences between Sparse and KLU. Differences are probably expected and in a few cases are ~1-2%, sometimes a little more. This should be good enough for most CIDER analyses. Francesco did a good piece of work. Runtimes are significantly shorter with KLU.	7 months ago
