Hello Michael,
I am working with the Viewlogic tooling for 2 years now. I haven't had
the
chance to look at Spectraquest though, so I only can say something about
the
Viewlogic tooling. One of the advantages of Viewlogic is that they have
a
tooling called ISIS scratchpad. This tooling is now implemented into the
E
Product Planner (tooling used for floorplanning, constrain management
etc.).
Scratchpad is a pre-layout signal integrity tooling. So you can load
your
Viewlogic schematic into the tooling and perform a signal integrity
analysis. Play with termination and topology, those kind of things. XTK
has
also an interface with Allegro. Five files are required: via.dat,
def.dat,
comp.dat, board.dat and layer.dat. Hopefully this is useful information
for
you.
