The Clock Interaction report analyzes timing paths that cross from one clock domain (the source clock) into another clock domain (the destination clock). Use this report to identify potential issues such as data loss or metastability.
After you run the Report Clock Interaction command, the results appear in the Clock Interaction window. The report displays as a matrix, with:
- Source clocks listed along the vertical axis
- Destination clocks listed along the horizontal axis

This matrix format helps you quickly spot interactions between clock domains that might need further review.
