How to set constraints in map？

[hemingxiao-3]

I am a novice in this field, please forgive my stupidity.

I'm wondering if it's possible to set timing constraints for each PI and PO when doing the map.

For example, I want to set the max delay for each PI and PO pair, which means that the mapped netlist cannot exceed the value I set for the delay of these PI and PO pairs.

It is best to be able to implement strict constraints, but a bit of relaxation is also acceptable.
