Thanks for the reply. I did install plug-in models suggested. But, I am not clear how to utilize them.For example how should refer to PIN diode model & its parameters in my circuit ? I notice make process has placed foo.o files & foo.so in respective folders. Do I need to execute them to generate model or just refer to them in my circuit model?
