zspice.

zspice is an analog circuit simulator inspired by SPICE engines. it is an recreational learning project, to understand how SPICE engines work, and how common components are modelled.

for the mock-up version check this repo. there i tried making a quick resistor network solver in python, then tried porting it to C++

Build Instructions.

Requires CMake, also Ninja is nice to have.

git clone https://github.com/zoomlogo/zspice
cd zspice
mkdir build && cd build
cmake ..
ninja
./test_run           # to run the tests
./zspice             # actual program

Doc Build Instructions.

Requires doxygen.

doxygen  # output in docs/

TODO

See TODO for info.

COPYING

See COPYING for info.
