Read SDC File Command

You access this command by double-clicking Read SDC File in the Tasks pane in the TimeQuest Timing Analyzer.

Reads existing Synopsys Design Constraints File (.sdc) Definition— with all current constraints and exceptions— that are specified in user-defined order in the Quartus Prime Standard Edition Settings File (.qsf) Definition. If a Synopsys Design Constraints File is not specified in the Quartus® Prime Standard Edition Settings File, the TimeQuest analyzer reads a default Synopsys Design Constraints File named <revision>.sdc. This command also produces the SDC File List report, which lists all Synopsys Design Constraints Files in the current design.

Note:

If you access the Read SDC File command from the Constraints menu in the TimeQuest analyzer, you must select an Synopsys Design Constraints File from your local disk.
