Hello Pat,
You might want to try Expedition PCB from Mentor Graphics. With CES =
(Constraint Editor System) driving the AutoRouter, the power of =
AutoRouter can be controlled and harnessed to route high-speed nets. =
Critical nets with custom topologies and even differential pairs can be =
auto-routed with ease with the help of CES. CES working with AutoRouter =
can also help the designer to auto-tune the nets for matching lengths =
and timing analysis.
Here are some links to the Mentor web site on the Expedition Flow:

Subject: [SI-LIST] PCB differential auto-routers
We're finding challenges with some commercial auto-routers when dealing =
with complex boards containing many (100's to 1000's) of differential =
nets. In particular, a tool that obeys our SI-related constraints, such =
as pair-to-pair pitch, space to ground voids, etc.
Anyone have a tool they'd recommend for auto-routing large PCBs that =
contain many differential nets?
Thanks,
