Performing Timing Analysis in the
Quartus II Software
The Timing Analyzer automatically performs timing analysis on your
design during a full compilation. The following guidelines describe some of
the tasks that you can accomplish with the Quartus II Timing Analyzer:
■ Specify initial project-wide and individual timing requirements, using
the Timing Wizard (Assignments menu), the Settings dialog box
(Assignments menu), and the Assignment Editor.
■ Perform the timing analysis during a full compilation or separately
after an initial compilation.
■ Perform an Early Timing Estimate after a partial compilation, before
fitting is complete.
■ View the timing results using the Report Window, Timing Closure
floorplan, and list_path Tcl command.
Specifying Timing Requirements
Timing requirements allow you to specify the desired speed performance
for the entire project, for specific design entities, or for individual entities,
nodes, and pins.
You can use the Timing wizard to help you to create initial project-wide
timing settings. Once you have specified initial timing settings, you can
modify settings either by using the Timing wizard again, or by using the
Timing Requirements & Options page of the Settings dialog box. Figure 2
shows the Timing Requirements & Options page.
