how to use the TimeQuest to constrain the clock skew

[Altera_Forum]

In the Classic Timing Analyzer,these is a constrain named "Maximum Clock Arrival Skew",but it is not supported in the Quartus II TimeQuest Timing Analyzer,how to i do to constrain the clock skew in the Timequest? 

THX!

The SDC command for clock skew is 

  set_clock_uncertainty <your_uncertainty> <clock>   I might have the syntax wrong, but that's the name of the command.  You can add this to the sdc file that timequest generates, then next time you open timequest and it reads the file it will load the setting.

While some causes of clock skew can add to clock uncertainty, set_clock_uncertainty is not a command to constrain clock skew. The on-line help page for the command does mention skew, but what the command actually does is tell TimeQuest how far the clock edge can move away from the ideal position (for example, a clock edge moving around because of jitter).
