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!
