Constraint | Check | Worst Case | Best Case | Timing | Timing
| | Slack | Achievable | Errors | Score
------------------------------------------------------------------------------------------------------
* TS_pro_clk = PERIOD TIMEGRP "pro_clk" 7 n | SETUP | -2.246ns| 9.246ns| 46| 52630
s HIGH 50% | HOLD | 0.290ns| | 0| 0
------------------------------------------------------------------------------------------------------
* OFFSET = OUT 6 ns AFTER COMP "pro_clk" | MAXDELAY| -2.035ns| 8.035ns| 37| 50787

Re: slack issue..

Did you give proper constraint to your design using sdc file.

Can i see your sdc file that will help.
