No - I do not think there is any way of getting the *autorouter* to try
smaller tracks as the density rises. Maybe the (mythical?) major
autorouter upgrade will do this?
Colby gave info on changing the track width during manual routing. You may
be able to kludge your way by letting the router route using the preferred
width and then when it fails at 90% or whatever go around using the various
select functions and the global operations to shrink the tracks and then
rerun the autorouter - it may then be able to push these thinner tracks
about to help complete the task. A big kludge. Alternatively, you may
need to set up more width design rules and set the preferred width of the
vast bulk of your signal tracks to the smaller width - at least during
autorouting. You can use net classes for this task.
