The Report Utilization Report helps you analyze the utilization of the design with different resources, at the hierarchical, user-defined Pblocks, or SLR level. You can generate the Utilization Report during various steps in the flow with the report_utilization Tcl command. (For details on Tcl command usage see the Vivado Design Suite Tcl Command Reference Guide (UG835).) The report details shown below are for UltraScale and UltraScale+ families. It includes the device used for the run and utilization for the following (additional items might appear in each category):

  • Slice Logic
    • LUT
    • MuxFx
    • Register
    • Slice
    • LUT as Memory
    • LUT Flip-Flop pairs
    • LUT as Logic
  • Memory
    • BlockRam
    • FIFO
  • DSPs
  • I/O Resources
  • Clocking Resources
  • Specific Device Resources. Examples:
    • STARTUPE2
    • XADC
  • Primitive type count sorted by usage
  • Black Boxes
  • Instantiated Netlists
  • SLR Crossing Utilization

When run from the Tcl console, the report can include usage of a particular hierarchical cell when using the -cells option. When run from the Vivado IDE, this information appears in an interactive table.

The numbers may change at various points in the flow, when logic optimization commands change the netlist.
