Open SDC File Command (TimeQuest Timing Analyzer)

You access this command by clicking File > Open SDC File in the TimeQuest Timing Analyzer.

Opens a selected Synopsys Design Constraints File (.sdc) Definition in the Quartus^® Prime Text Editor or an external text editor specified on the Text Editor page of the Quartus^® Prime Text Editor Options dialog box.

Note: The TimeQuest analyzer does not apply constraints and exceptions specified in the SDC File until you use the Read SDC File command. To re-read constraints and exceptions from the start, use the Reset Design command, and then the Read SDC File command.
