Title: basic doubts
Post by raja.cedt on Jan 31^st, 2010, 3:22am

hi,
1. whats the difference between .ic and nodeset in hspice?
2. I am not able to get info from .pz results in hspice? it is listing so many pz's even for two stage opamps.

Thanks,
Rajasekhar.

1 .ic is enforced at time=0, eg an initial condition for an oscillator.
Nodeset is a hint to the Newton solver, so it will start "near" the true solution, but the actual time=0 solution may be "far" from the nodeset.
