circuitmaker lib
Hi,
Could someone help me to apply a varistor model in Circuitmaker 2000 ???
I found following models but I do not know how to change this syntax according to CM2000 spice syntax requirements (this is taken from SIEM.LIB file) ?

Example of CM2000 Zener diode model (I think the easiest way is to put varistor model to this part for example):
