Interactive timing analysis provides instant reports on timed circuits that contain new timing constraints. You can add or edit a timing constraint file and issue a report_timing command without having to go through the entire synthesis flow again. Precision Synthesis uses the PreciseTime timing analyzer to perform the analysis. Issue a timing report by clicking on the "Report Timing" icon in the Design Analysis taskbar, or type report_timing (alone or with one of 35 command switches) on the Precision Synthesis command line.

Timing reports can be generated directly from selected objects in the Schematic Viewer, Design Browser and Graphical Find window. You can cross-reference objects in the timing report back to the schematics.
