How do I specify different timing constraints for TimeQuest, Fitter, or Analysis & Synthesis? - How do I specify different timing constraints for TimeQuest, Fitter, or Analysis & Synthesis? Description To identify which executable is currently running you can use the $::TimeQuestInfo(nameofexecutable) command from within a Synopsys Design Constraints ( .sdc ) file. This method can be used to specify different .sdc assignments or files for specific executables as shown in the following .sdc examples: #Identify which executable is running: set current_exe $::TimeQuestInfo(nameofexecutable) if {$current_exe == "quartus_fit" } { #Apply .sdc assignments for Fitter executable here } else { #Apply .sdc assignments for non-Fitter executables here } if { ! [string equal "quartus_sta" $::TimeQuestInfo(nameofexecutable)] } { #Apply .sdc assignments for non-TimeQuest executables here } else { #Apply .sdc assignments for TimeQuest executable here } Examples of different executable names are quartus_map for Analysis & Synthesis, quartus_fit for Fitter, and quartus_sta for the TimeQuest timing analyzer.
