Dynamic Function eXchange requires all the same constraints as any other design, and requires additional physical constraints (Pblocks) and might require various sets of constraints that define the various configurations defined by a set of RMs. Constraints be defined as either global or scoped.

Global
These are constraints that are applied to the entire design, and all object references (cell/pin/net/port) are with respect to the full design hierarchy.
Scoped
These are constraints that are written with respect to a module other than the top module and are scoped to a single or all instances of that module. For the following discussion on Dynamic Function eXchange, it is assumed scoped constraints are scoped to one or more instances of a RM. For more information on XDC scoping, see this link in Vivado Design Suite User Guide: Using Constraints (UG903).
