[-removal] [-setup] [-stdout]
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-file <name>: Sends the results to an ASCII or HTML file. Depending on the extension

-panel_name <name>: Sends the results to the panel and specifies the name of the new
panel
-recovery: Recovery Analysis

Description
Reports the worst-case Clock Setup and Clock Hold slacks and endpoint TNS (total negative slack) per
clock domain. Total negative slack is the sum of all slacks less than zero for either destination registers or
ports in the clock domain.
This command shows the worst-case slack for each clock domain. You right click in these reports to run
more detailed reports like Histograms and Report Timing.
By default, this command creates a Setup Summary. This command can also generate a Hold Summary
(-hold), Recovery Summary (-recovery), Removal Summary (-removal), or Minimum Pulse Width
Summary (-mpw).
The report can be directed to the Tcl console (-stdout, default), a file (-file), the TimeQuest graphical
interface (-panel_name), or any combination of the three.

# Create Clock Domain Summary
create_timing_summary -panel_name "Setup Summary"
create_timing_summary -hold -panel_name "Hold Summary"
# The following command is optional
