Performance Summary

Worst slack in design: 5.124
Requested Estimated Requested Estimated Clock Clock
Starting Clock Frequency Frequency Period Period Slack Type Group
------------------------------------------------------------------------------------------------------------------
CLK 44.3 MHz 114.2 MHz 22.558 8.754 8.522 declared default_clkgroup
PHI0 1.0 MHz 3.2 MHz 977.000 310.881 5.124 declared default_clkgroup
System 100.0 MHz NA 10.000 NA NA system system_clkgroup
==================================================================================================================
Estimated period and frequency reported as NA means no slack depends directly on the clock waveform
Clock Relationships
*******************

PHI0 CLK | No paths - | No paths - | No paths - | 7.515 5.124
=========================================================================================================
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.
