s-nap pcb suite software know how

I found a software about PCB and Microwave simulation tools 'S-Nap pcb suite'
But it's not enough information about how to use it.
I wanna ask Edaboard seniors, any guys use it before?


I have some question , that if simulate Signal integrity, shall it need import gerber files, drill files, dsn files, or location files? or indivial of it can ok.

thanks
