Running Report Bus Skew - 2025.2 English - UG906

You can run the Bus Skew report in two ways:

1. From the Tcl Console use the report_bus_skew command. This method gives you access to advanced options, including:
   • -cells to scope the report to one or more hierarchical cells. The report includes only paths where the datapath section starts, ends, or is fully contained within the specified cells.
   • -sort_by_slack to sort the constraints in ascending order of slack, from smallest to largest.
2. From the Vivado IDE, select Reports > Timing > Report Bus Skew.
   Note: The IDE does not support the -cells option.

The command shares many filtering and formatting options with report_timing, allowing you to customize the output. Constraints appear in the order you defined them unless you apply the -sort_by_slack option that sort the constraints in an ascending order, from the smallest to the largest slack.
