7.7.3. Creating a Design Partition
A design partition is a logical, named, hierarchical boundary that you can assign to an instance in your design. Defining a design partition allows you to optimize and lock down the compilation results for individual blocks. You can then optionally export the compilation results of a design partition for reuse in another context, such as reuse in another project.
Figure 56. Design Partitions in Design Hierarchy
Follow these steps to create and modify design partitions:
- In the Quartus® Prime software, open the project that you want to partition.
- Generate synthesis or final compilation results by running one of the following commands:
- Click Processing > Start > Start Analysis & Synthesis to generate synthesized compilation results.
- Click Processing > Start Compilation to generate final compilation results.
- In the Project Navigator, right-click an instance in the Hierarchy tab, click Design Partition > Set as Design Partition.
Figure 57. Creating a Design Partition from the Project Hierarchy
- To view and edit all design partitions in the project, click Assignments > Design Partitions Window.
Figure 58. Design Partitions Window
- Specify the properties of the design partition in the Design Partitions Window. The following settings are available:
Table 34. Design Partition Settings Option Description Partition Name Specifies the partition name. Each partition name must be unique and consist of only alphanumeric characters. The Quartus® Prime software automatically creates a top-level (|) "root_partition" for each project revision. Hierarchy Path Specifies the hierarchy path of the entity instance that you assign to the partition. You specify this value in the Create New Partition dialog box. The root partition hierarchy path is |. Type Double-click to specify one of the following partition types that control how the Compiler processes and implements the partition: - Default—Identifies a standard partition. The Compiler processes the partition using the associated design source files.
- Reconfigurable—Identifies a reconfigurable partition in a partial reconfiguration flow. Specify the Reconfigurable type to preserve synthesis results, while allowing refit of the partition in the PR flow.
- Reserved Core—Identifies a partition in a block-based design flow that is reserved for core development by a Consumer reusing the device periphery.
Empty Specifies an empty partition that the Compiler skips. This setting is incompatible with the Reserved Core and Partition Database File settings for the same partition. Partition Database File Specifies a Partition Database File (.qdb) that the Compiler uses during compilation of the partition. You export the .qdb for the stage of compilation that you want to reuse (synthesized or final). Assign the .qdb to a partition to reuse those results in another context. Entity Re-binding - PR Flow—specifies the entity that replaces the default persona in each implementation revision.
- Root Partition Reuse Flow —specifies the entity that replaces the reserved core logic in the consumer project.
Color Specifies the color-coding of the partition in the Chip Planner and Design Partition Planner displays. Post Synthesis Export File Automatically exports post-synthesis compilation results for the partition to the specified .qdb file each time Analysis & Synthesis runs. You can automatically export any design partition that does not have a preserved parent partition, including the root_partition. Post Final Export File Automatically exports post-final compilation results for the partition to the specified .qdb file each time the final stage of the Fitter runs. You can automatically export any design partition that does not have a preserved parent partition, including the root_partition.
