LTspice tutorial - Simulation models - How to check their accuracy?

#49 #ltspice This time I analyze some methods to verify simulation models in LTspice and see exactly just how accurate they are. These are not all the methods of course but this tutorial can give you an idea about what can be done to check if the models you are using are actually accurate.
