Step 3: Creating Design Partitions
You must create design partitions for each PR region that you want to partially reconfigure. You can create any number of independent partitions or PR regions in your design. This tutorial creates two design partitions for the u_blinking_led_child and u_blinking_led instances.
To create design partitions for hierarchical partial reconfiguration:
- Right-click the u_blinking_led_child instance in the Project Navigator and click . A design partition icon appears next to each instance that is set as a partition.
Figure 3. Creating Design Partitions from Project Navigator
- To define the partition Type, right-click the u_blinking_led_child instance in the Hierarchy tab, click . You can only define the partition Type after setting the instance as a partition.
The design partition appears on the Assignments View tab of the Design Partitions Window.Figure 4. Design Partitions Window
- Edit the partition name in the Design Partitions Window by double-clicking the name. For this reference design, rename the partition name to pr_partition.
Note: When you create a partition, the Intel® Quartus® Prime software automatically generates a partition name, based on the instance name and hierarchy path. This default partition name can vary with each instance.
- Repeat steps 1 and 2 to assign reconfigurable design partitions to the u_blinking_led instance. Rename this partition to pr_parent_partition.
