Note: If you run both cost-based and delay-based cleanup passes, the
cost-based passes run first.

Select Allow Re-entrant Routing to route the previously
routed design again.
Select a number between 1 and 5 for the Run _ Cost-Based
Cleanup Passes field.
These cleanup passes reroute nets if the new routing uses less
costly resources than the original configuration. Cost is based on
pre-determined cost tables. Cost-based cleanup usually has a
faster runtime than the delay-based cleanup, but does not reduce
delays as significantly.
Select a number between 1 and 5 for the Run _ Delay-Based
Cleanup Passes field.
These cleanup passes reroute nets if new routing will minimize
the delay for a given connection. Delay-based cleanup usually
produces faster in-circuit performance.
Select a number between 1 to 2000 for the Run _ Re-entrant
Route Passes field to run additional re-entrant routing passes.
These passes are either timing driven or non-timing driven
depending on whether you specified timing constraints.
Select Use Timespecs During Re-entrant Route if you want
to reroute the design within the specified timing constraints in
your design file.
