Stratix 10 timing result much worse than Arria 10

Hi,

I'm porting design from Arria 10 to Stratix 10, I use Quartus Prime 17.1 for Arria 10, Quartus Prime Pro v2020.2 for Stratix 10. 

I got much worse timing result on Stratix 10 than Arria 10. For example, a clock defined at 13ns period, I got -10ns slack for S10, however it is -1ns for A10. 

I have check the -10ns slack is not due to clock skew, it is single clock domain with no crossing. 

What am I missing when porting design from A10 to S10? Any suggestion is welcomed. 

Thanks.

Due to architecture change for Stratix 10, it will require different method for timing closure in S10. You can refer to the link below for more information:
