Hi,

I intend to add a new device to the Spice (e.g. ngSpice ), which is implemented by 3 nonlinear differential equations.

I shoud say that I am a complete novice. I have installed the ngSpice25. The ngSpice is composed of many Programms and folders and subfolders. I have no idea how can I look through the construction of ngspice in order to add a new device to it.

My device is already implemented in Mathematica. If I implement it in C , is there any possibilty to connect it to the Spice ?or is there any other way to do it, so that my device is also adaptable by Spice?

I would be very grateful for your hints in advance.

Best regards

Nina
