Thanks for your support! The models you mention are part of CIDER, which is a device-level simulation framework within ngSpice. While it is on my wishlist to have device-level simulations...

I've been thinking about this issue lately and it seems to me that the only case where this feature is useful is for transient/time-based analysis. For DC, AC and Noise...

Hi, Spice has a pretty (in my opinion) confusing way of handling initial conditions. I believe that what you did was specify an initial condition on the capacitor, while in...

Thanks for checking! I think this would be a good time to take a look at the `UseIc` behavior and write some tests and possibly fix the bugs if it...

I've given the UIC behavior an overhaul, but it still needs tests to make sure everything operates as expected. I would like to keep this issue open for a little...

Well, I think you might be best off combining a voltage-controlled switch with a voltage source (I'm assuming you mean a "constant voltage drop" model). If you connect the control...

Hi, I seem to have missed this post, so sorry for the late reply. At the moment there is no direct support for digital components, although I already added some...

I'm working on my own implementation of the Martinez paper, and I started there from the original implementation in C++ that they published (I need integer coordinates). Since I was...

Hi, I currently don't have the intention of adding LTSpice-only features in the core package (also, LTSpice is closed source so the best I could do is emulate the behavior)....

PySpice is not really a simulator, it does reference ngSpice and Xyce however. I could not find the implementation in ngSpice ([their loading behavior](https://github.com/ngspice/ngspice/blob/master/src/spicelib/devices/sw/swload.c)). Perhaps they transform a negative hysteresis...
