In Versal, the majority of clocking resources
appear in the bottom horizontal super row (HSR). 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.
Figure 1. Clocking Resources
Clock Routing expansion automatically picks up required clock tiles for routing even though clocking resources are in separate island of Pblock.
