Clock Relationships
*******************
Clocks | rise to rise | fall to fall | rise to fall | fall to rise
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Starting Ending | constraint slack | constraint slack | constraint slack | constraint slack
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

==========================================================================================================================================================================
Note: 'No paths' indicates there are no paths in the design for that pair of clock edges.
'Diff grp' indicates that paths exist but the starting clock and ending clock are in different clock groups.
