I have been unable to get the AD8336.lib run in Qspice, I have two libraries, one from LTspice and another from Analog Devices. The LTspice one works fine in LTspice but I am interested in Qspice, anyone with the right library?
If you referring to standard SPICE model which can download from AD website, AD8336 Datasheet and Product Info | Analog Devices
There are multiple characters that in the subcircuit netlist which cannot be recognized by Qspice.
A function nonzero() which doesn’t support in Qspice/LTspice. From this E-source formula, I guess it is to prevent divided by 0.
By reading your message, it seems you have a non A-device model that can work in LTspice. But I don’t think this .cir download directly from AD website can work in LTspice without modifying. So, somehow you have a subcircuit model not with A-device but can work in LTspice for AD8336?
Here I modified the subcircuit for Qspice, follow example that in LTspice.

This is a screen capture run with LT A-device model.
