Create a ngspice compatible model which doesn't use Verilog-A

[mithro]

It would be nice to have a ngspice compatible spice model of the ReRAM cell which doesn't use a Verilog-A file.

Or a version of ngspice that can compile Verilog-A models as plug-ins. I see this as a major drawback of ngspice that is something that is probably very easy to implement by anyone who knows how to do plug-in shared object libraries.

I'm not aware of any compact spice models for ReRAM devices. Are there any?

Since ngspice-39 there is now a way to add Verilog-A compact device models into ngspice. Please see https://ngspice.sourceforge.io/osdi.html and chapter 13 of the current ngspice manual.

In addition there are two memristor models available in ngspice (see ngspice\examples\memristor), which might be modified and adapted to ReRAM devices. One is a behavioral model with B sources, the other is an analog (C-coded) XSPICE model.
