The clock constraint appears in the SmartTime Constraints Editor (as shown in the figure below).

8. From the
File
menu, choose
Save
to save the constraints.
9. From the SmartTime
File
menu, choose
Exit
to exit SmartTime. Libero creates a constraint file to
store the clock constraint. This file is listed and displayed in the Constraint Manager. It is named
user.sdc and is designated as Target.
Note
: A target file is used to store newly added constraints from the Constraint Editor. When the
Constraint Editor is invoked and no SDC timing constraint file is present, Libero SoC creates the
user.sdc file (and marks it as target) to store the timing constraints you create in the Constraint Editor.
10. In the Constraint Manager, check the checkbox under Place and Route and the checkbox under
Timing Verification to associate the constraint file to the tools. The constraint file is used for both Place
and Route and Timing Verification.
