- Read the post-placed checkpoint into Vivado Design Suite.
- Add a constraint to disable all hold checking:
set_false_path -hold -to [all_clocks]CAUTION:This constraint is for test purposes only. Never do this for designs that will be put into production or delivered to another designer. You must remove this constraint before the production design.
If there is a significant difference between the WNS with and without the hold checks, the hold violations might be too large, and the setup paths are being affected.
