The CONTAIN_ROUTING property restricts the routing of signals contained within a Pblock to use routing resources within the area defined by the Pblock. This prevents signals inside the Pblock from being routed outside the Pblock, and increases the reusability of the design.
By default the definition of a Pblock restricts the placement of logic assigned to
the Pblock to within the area defined by the Pblock. This property has the same
effect for routing. The CONTAIN_ROUTING property is specific to a Pblock and must
come after the
create_pblock commands in an XDC file.
Only signals that are entirely owned by the Pblock cells will be contained within the Pblock. For example, if no BUFGMUX resources are found within the Pblock, paths from or to a BUFGMUX cannot be contained.

- Contain the routing of signals inside a Pblock to the area defined by the Pblock range.
- Do not contain the routing of signals inside the Pblock. This is the default.
