John,
The option "-prioritize_min_paths" in compile is still available for
backward compatibility. This option has not been removed or moved to
DC Ultra. With the new min/max optimization capability in Design
Compiler, there is less need to use the "prioritize_min_paths" option.
Thus, when you tried using it, the tool will generate a warning but
it will still optimize the design with min paths taken as a design rule.
This is to ensure that existing scripts using a 2-pass compile approach
for optimizing max and min separately will still work.
