ignore) paths between unrelated clock domains when there are no
timing requirements set or only the default required f MAX clock setting
is used. The Quartus II software also cuts paths between unrelated
clock domains if individual clock assignments are set but there is no
defined relationship between the clock assignments.
Maximum delay requirements —Requirements for input or output
maximum delay, or maximum timing requirements for t SU , t H , t PD , and
t CO on specific nodes in the design. You can make these assignments to
specific nodes or groups to override project-wide maximum timing
requirements.
Minimum delay requirements —Requirements for input or output
minimum delay, or minimum timing requirements for t H , t PD , and t CO
for specific nodes or groups. You can make these assignments to
specific nodes or groups to override project-wide minimum timing
requirements.

Using the quartus_sta executable
You can also run the TimeQuest analyzer separately at the command prompt or in
a script by using the quartus_sta executable. You must run the Quartus II Fitter
executable quartus_fit before running the TimeQuest analyzer.
The quartus_sta executable creates a separate text-based report file that can be
viewed with any text editor.
You can also launch the quartus_sta Tcl scripting shell, to run timing-related Tcl
commands, by typing the following command at a command prompt:
quartus_sta -s
r
If you want to get help on the quartus_sta executable, type one of the following
commands at the command prompt:
quartus_sta --h r
quartus_sta --help r
quartus_sta --help = <topic name>
r
Additionally, the quartus_staw executable provides the GUI for the TimeQuest
analyzer as a stand-alone application.
