Question on ansoft designer

I am a beginner for ansoft designer, and I use it to design some RF blocks
now I have mos lib file in spice format, and some example circuits.
I wonder if I could import both lib file and simulate the circuits with these lib files.
and if it does work, how should I do?
could anybody give me a hand in somewhat detail?

moreover, if I have both lib files and design circuits in spice format,
can I import both of them and run a simulation?

thank you
