Hua,

In Quartus II 9.0, some physical synthesis optimizations are carried out during the Analysis & Synthesis stage, and some are carried out during Fitter stage. So depending on physical synthesis options you have turned on, Analysis and Synthesis could take longer.

IIRC, when the physical synthesis effort level is set to Fast, physical synthesis optimizations are done only during Analysis & Synthesis. That might explain the increase in memory usage during this stage too.
