Intra-Clock Paths Section - 2025.2 English - UG906

The Intra-Clock Paths section of the Timing Summary Report displays the worst slack and total violations for timing paths that share the same source and destination clock.

To view detailed information:, click the names under Intra-Clock Paths in the left index pane. For example, you can view the slack and violations summary for each clock and details about the N-worst paths for SETUP/HOLD/Pulse Width checks. The N-worst is defined by running -max_paths on the command line or the maximum number of paths per clock or path group.

1. In the left index pane, click any entry under Intra-Clock Paths.
2. Review the slack and violation summary for each clock.
3. Examine the N-worst paths reported for each analysis type:
   • Setup
   • Hold
   • Pulse Width
   The N-worst paths are determined by the -max_paths value in the Tcl command option or by the maximum number of paths per clock or path group set in the GUI.

Next to each analysis label, you can see the worst slack value and the number of reported paths. When you select a Setup summary (or Hold or Pulse Width), the report displays a table on the right showing all paths related to that clock.

Use this section to quickly identify the most critical timing paths within the same clock domain.
