The Timing Constraints window is available for Synthesized and Implemented designs only. For elaborated design constraints, use and edit XDC files directly. For more information, see Creating Synthesis Constraints.

  • Select Window > Timing Constraints.
  • In the Synthesis section of the Flow Navigator panel, select Synthesized Design > Edit Timing Constraints.
  • In the Implementation section of the Flow Navigator panel, select Implemented Design > Edit Timing Constraints.
Figure 1. Multiple Methods for Opening the Timing Constraints Window

The Timing Constraints window displays the timing constraints in memory, in either the same sequence as in the XDC files and Tcl scripts, or the same sequence in which you entered them in the Tcl Console.

Some of the constraints cannot be edited from this window. They are marked with the XDC No Edit icon .
