Guidance Summary information is displayed in the Run Guidance tab.

Figure 1. Run Guidance Tab

The preceding image shows the run guidance for your hardware run, providing suggestions on ways to potentially improve the performance of your design. Two rules are provided for AI Engines: AIE_STALL and AIE_UTILIZATION. The rule AIE_STALL checks for tiles that have stall times of less than 20% of active times. If this threshold is not met, then a resolution is provided, including a link to more information on how to potentially improve your design.

The rule AIE_UTILIZATION checks for tiles that have utilization greater than 50%. Similar to AIE_STALL, if this threshold is not met, then a resolution is provided, including a link to more information on how to potentially improve your design.

To change the threshold values for either rule, click on the threshold value link, and a dialog box pops up, allowing you to modify the value to any value between 0 and 100. See Vitis Unified Software Platform Documentation: Application Acceleration Development (UG1393) for more information on how to use and interpret guidance results for all types of Vitis tools flows.
