Dear Luca:
Thanks for your good question. =20
First let me mention that I really like PSpice due to several reasons =
including:
i. It allows graphical schematic entry of the design.
ii. It is quite easy to learn (and work with).
iii. A free version (however, with a limitation on maximum number of =
components) is available.
On the other hand, PSpice has some important drawbacks in comparison to =
HSPICE. For example, IBIS models cannot be directly used by PSpice =
(and it is often necessary to approximate an IBIS models with VPULSE or =
VPWL); whereas, HSPICE allows direct utilization of IBIS models.=20
HSPICE also offers a wider choice for transmission line modeling, such =
as lossless (T-element), and lossy (W-element); plus a field solver for =
generating RLGC matrice.=20
Additionally, there are certain SPICE models which can be directly =
simulated only with HSPICE. =20
There are many HSPICE experts on the si-list and hopefully they will =
explain why HSPICE is their preferred choice for SI simulations.

Abe Riazi

About spice simulators, I always wondered why SI-people is especially
devoted to the HSpice. At least, this is my feeling following the
discussions on this list.
Why is PSpice less interesting from an SI point of view? Does it support
IBIS models?
