Hi! I'm just beginning to experiment with SI Simulation tools (specifically SiSoft) and I noticed to run a simulation you need to select corner and etch options conditions. The options are slow, typical, and fast corners and slow, typical and fast etch, and combinations of the two. I was wondering if someone could explain to me how these options relate to the simulation, and what methods are used to decide which options to use. In other words, a big picture overview would be very helpful. I did read that the corner options select temperature and voltage factors, and the etch selects propagation delay and impedance factors, but that's about all I understand so far. Thanks!
