From the Performance Metrics view, you can identify if a stream stall needs to be analyzed, and also the tile/tiles that are causing the stall.

The following steps illustrate how a stream stall can be analyzed starting in the Performance Metrics tab in the Vitis IDE.

  1. In the Performance Metrics view, select Stream Stall Time (%) to view stream stalls across all tiles. Identify the tile(s) to be analyzed. Note that the objects in Performance Metrics view can be cross-probed with Trace view, Graph view, and Array view. For example, selecting the tile in the Performance Metrics view to highlight the tile in Trace view can help quickly locate the tile.

  2. Select the Trace view.
