The EXCLUDE_PLACEMENT property is used to indicate that the device resources inside of the area defined by a Pblock should only be used for logic contained in the Pblock.
The default is to allow the Vivado placer to place logic not assigned to a Pblock within the range of resources reserved by the Pblock. This property prevents that, and reserves the logic resources for the Pblock.
Note: This only closes the Pblock's logic resources.
Outside logic can still use routing resources within the area defined by the
Pblock.

-
-
TRUE: Reserve the device logic resources inside a Pblock for use by logic assigned to the Pblock, thus preventing placement of outside logic. -
FALSE: Do not reserve logic resources inside the Pblock.
