In Versal, majority of clocking resources appears in bottom HSR
row. Since most of the clocking resources are located at bottom row of the device, users
can have an island for reconfigurable Pblock in the bottom HSR if they need internal
clocking resources inside the reconfigurable partition. For example, in the following
figure rp1 Pblock is split into two rectangles, one for
the placement of logic and other for the placement of clocking resources.

Clock Routing expansion automatically picks up required clock tiles for routing even though clocking resources are in separate island of Pblock.
