Generating the QoR Suggestion Report - 2025.2 English - UG906

You can generate a QoR Suggestions report in the Vivado IDE or through the Tcl Console.

1. Generate the report:
   • In the Vivado IDE: Select Reports > Report QoR Suggestions.
   • In Tcl: report_qor_suggestions -name qor_suggestions_1
2. Adjust the report parameters:

   Number of timing paths to analyze

   This expands the number of suggestions but might include paths that are not critical.

   • In the GUI: Change Number of paths for suggestion analysis. The default is 100.
   • In Tcl: -max_paths <N>

3. Number of ML strategies to suggest

   • In the GUI: Change Maximum Number of Strategies to suggest.
   • In Tcl: -max_strategies <N>

   Report all suggestions

   This option includes suggestions that do not violate threshold criteria:

   • Timing suggestions include paths even if timing is met.
   • Utilization suggestions include non-critical resource suggestions.
   • Congestion suggestions include post-route suggestions even if timing is met.

   • In the GUI: Select the Report all suggestions checkbox.
   • In Tcl: -report_all_suggestions

   Generate CSV files for failing paths

   This creates:

   • A CSV file listing failing timing paths and their associated suggestions
   • A second file containing a DONT_TOUCH report

   • In the GUI: Check the box to generate CSV files and specify a directory.
   • In Tcl: -csv_output_dir <directory>

   Note: Use caution when removing DONT_TOUCH properties. Vivado can apply these automatically:

   • Do not remove DONT_TOUCH from static or reconfigurable modules in a DFX flow. These prevent cross-boundary optimizations.
   • Optional to remove DONT_TOUCH from signals marked with MARK_DEBUG. These do not affect the flow but prevent the signal from being optimized or available for hardware probing.
