Using Partitions - To Use Partitions
To use Partitions follow the suggested options.
To Use Partitions
  1.  In the Project Navigator graphical environment Partitions are created in the Sources tab. This view displays the design hierarchy. To create a Partition, right-click the instance and select New Partition.
  2.  The Tcl command partition new <partition-name> creates a new Partition for an instance. Use this command in a Tcl script, or execute from the Tcl Shell tab, to create Partitions in the Tcl environment.
  •  The Partition implementation data can be re-used on subsequent implementations if that Partition has not been modified. If the Partition has been modified, such as by an HDL source change or a physical constraint change,  it will be re-implemented.  A Partition membership change will force all affected Partitions (such as parent and child Partitions) out of date.
  •  Some actions will force all Partitions in the project out of date so that they all must be re-implemented.  These types of actions include:
    •  Timing constraint changes
    •  Process property changes (such as changing a map or par optimization)
    •  Removing implementation files, such as NCDs
  •  Force a Partition to be re-implemented, or set a Partition preservation trait so that a synthesized netlist, placement or routing are preserved only. See Partition Properties topic for more information.
