To filter the source clocks displayed in the Clock Interaction report:

  1. Click the settings button to display the Clock Visibility panel.
  2. Select the source clocks you want to view. The matrix automatically updates the list of destination clocks to match.

You can also simplify the view by hiding clocks that do not time any logical paths:

  • Click the Hide Unused Clocks button on the toolbar
  • These clocks are excluded by default because they do not affect WNS, TNS, WHS, or THS calculations
