Hi

It depends on your needs......If you need to run small circuits, it is okay
to use the PC version. Otherwise, Unix is preferable anyday !! I have had
many instances of PC-version crashing when running long and accurate
simulations ( eg. PLL ). Version 2000.2 (?) has problems with the 'Update'
feature in PC. I cannot track a waveform while simulation is running. (
There could be some fixes for these ! ).

As regards the links to 3rd party tools : the links help you to invoke
Hspice simulator other than the default simulator. For example, if you are
using Cadence's Analog artist, you would be able to use Hspice as a
simulator instead of CDSpice or Spectre.. the link provides the license to
do so. You could then analyse the results in the 3rd party's waveform
viewer. Of course, you need to have Hspice binaries too....i am not aware of
any Cadence or Mentor tools on PC. Mentor's NT support is probably close to
what you would want on a PC.
