Read Report Timing to view specific timing paths at any point of the flow after synthesis when you need to further investigate timing problems reported by Report Timing Summary, or you want to report the validity and the coverage of particular timing constraints. Report Timing does not cover Pulse Width reports.
When run from the Tcl console or the GUI, the timing report can be scoped to one or more hierarchical cells using the
-cells option. When the report is scoped, only paths with the datapath section that start, end, cross, or are fully contained inside the cell(s) are reported.
