Dear readers,
I am using the simulator within multisim. The GUI of the simulator is nice and shiny in my opinion compared with LTspice. However i experience that many models don't work. Am I the only one that has this problem or does others have the same experience.
For example a simple circuit left with a LT1018 comparator doesn't response at all at its out put. 
Hope to hear from you what your experience is .
