4.2.2.2. Entering Hierarchy Information Into the Intel® FPGA PTC
When entering levels of hierarchy in the Intel® FPGA PTC, the pipe character (|) denotes a level of hierarchy. For example, the following notation indicates three levels of hierarchy. Hierarchy a is the highest level. Hierarchy b is the second level. Hierarchy c is the third level.
a|b|c
Instance paths may, optionally, begin with a leading pipe character (|). But regardless of whether a leading pipe is is there or not, paths are treated the same.
When you enter an entity name for a given hierarchy, the Intel® FPGA PTC automatically updates the entity name in the Design Hierarchy tab of the Hierarchy Manager and on all data-entry pages that include that hierarchy.
To enter design hierarchy information into the Intel® FPGA PTC, follow these steps:
- Open your version of the Intel® FPGA PTC, as Accessing the Intel FPGA Power and Thermal Calculators describes.
- Click the View menu and select one of the Intel® FPGA PTC pages, such as the Logic page.
Figure 16. Intel® FPGA PTC Logic Page
- In the Full Hierarchy Name cell, type the hierarchical name of a hierarchy in your design, using the pipe character (|) as the hierarchy level delimiter. For example, the following defines the b level of hierarchy that is child of hierarchy a:
a|b

- In the Entity Name cell, enter the name of the design entity. If a newly entered hierarchy name already exists in the design, the Entity Name cell is already populated. Also, changing the entity name for a particular hierarchy name changes it for all_occurrences of that hierarchy name.
- Specify values for the #Half ALMs, #FFs, Clock Freq. (MHz), Toggle % and Routing Factor cells for each hierarchy. Repeat appropriate entries for design hierarchies on other pages.
The instance appears hierarchically in the Design Hierarchy in the Intel® FPGA PTC, showing the dynamic power estimate for each hierarchy level, and the cumulative power for all instances and hierarchy levels.
Figure 18. Intel® FPGA PTC Design Hierarchy - In the Design Hierarchy, you can right-click any instance to Rename, Duplicate, or Export the Intel® FPGA PTC data for the levels of hierarchy that you define.
