2.2.5. Tcl-only Script Flows

As an alternative to .sdc and .qsf files, you can perform all design assignments and timing constraints inside the Tcl scripts. In this case, the script that automates compilation and custom results reporting also contains the design constraints.

You can export a design's contents to a procedural, executable Tcl (.tcl) file, and then use the generated script to restore settings after experimenting with other constraints.

To export your constraints as an executable Tcl script, click Project > Generate Tcl File for Project.
