Altera recommends you use the TimeQuest timing analyzer. You can
specify that the TimeQuest timing analyzer be used by the Quartus II
software rather than the default Classic Timing Analyzer.
The TimeQuest timing analyzer validates the timing performance of all
logic in your design using an industry-standard constraint, analysis, and
reporting methodology. It provides powerful timing analysis features
that enable thorough timing analysis of high-performance designs. The
benefits of using TimeQuest for timing analysis include these features:

Classic Timing Analyzer supports HardCopy II timing analysis.
However, TimeQuest provides more powerful timing analysis features.
Some Classic Timing Analyzer timing constraints may not be translated
from the Quartus Setting file to SDC format constraints when the design
is transferred to the HCDC, because translating these constraints is
difficult and error-prone and often requires detailed analysis of the
particular context in which the constraint is used.
The timing closure methodology used in the Quartus II software for a
HardCopy II design is shown in
FPGA-first static timing analysis flow for either the TimeQuest timing
analyzer or the Classic Timing Analyzer. For the HardCopy II first flow,
the methodology is the same except that the HardCopy II compilation is
performed before the Stratix II compilation.
Native SDC support—You can leverage this powerful
industry-standard timing constraint format to achieve a higher
degree of productivity by using and reusing SDC- and Tcl-based
scripts.
Fast on-demand and interactive data reporting—This feature saves
time by allowing you to request more detailed timing analysis on
critical paths only. A powerful GUI reports the timing analysis data
in an intuitive graphical format that complements the fast,
on-demand data reporting, further enhancing productivity.
