NgSpice is an open-sourced electronics circuit simulation engine based on the venerable SPICE simulator developed and maintained at UC Berkeley during the 80s and 90s. It is the industry standard: to this day, SPICE simulation models are what vendors provide along their discreet device offerings.
This is a work in progress. Use at your own risk.
Known memory safety issues:
Type implementing PkSpiceManager moving in memory after calling init will crash once a callback is called.
Commanding bg_run creates a new thread
The following functions exposed by the API still need to be implemented
ngSpice_Init
ngSpice_Init_Sync
ngSpice_Command
ngGet_Vec_Info
ngCM_Input_Path
ngGet_Evt_NodeInfo
ngSpice_AllEvtNodes
ngSpice_Init_Evt
ngSpice_Circ
ngSpice_CurPlot
ngSpice_AllPlots
ngSpice_AllVecs
ngSpice_running
ngSpice_SetBkpt
Obtain the appropriate sharedspice lib from here. Sharedspice.dll for windows can be downloaded directly from the webpage. It is also available through homebrew. Linux binding is not tested.
The example code in main.rs and tests/lib.rs show how to specify the sharedspice path.
Compiling main.rs produces a simple command line program which passes messages between the user and NgSpice's command call. stdout, stderr, and stats are color coded. If you see something like this please open an issue detailing how to reproduce it.
Both main.rs and tests/lib.rs contain simple examples of how a manager may be implemented.
Any contribution is welcome.
sharedspice source code specifies that its memory are not to be freed by the calling program.
Callbacks may be called from a different thread and thus need to consider thread safety.
