Physical Hierarchy Configuration
is a physical hierarchy configuration utility that lets you specify how a layout implementation is generated from a specific schematic design.
The CPH window has three modes of operation.
|
Controls how the physical hierarchy is generated from your logical design, including which logical components are to be ignored in the physical implementation and which physical views are used to implement the logical components. |
|
|
Lets you view the library-level component types. In addition, this mode lets you create, edit, and remove the design-level component types, which identify the NMOS and PMOS transistor cells in the design and set the parameters for device chaining and folding. |
|
|
Lets you configure and specify bindings for the soft blocks that will be created by the Floorplan – Generate Physical Hierarchy command. You select the instances to be included and define the boundary, pin, and blockage parameters for the block you want to create. You can also remove the parameters from an existing soft block to prevent it from being created when the physical hierarchy is generated. To edit an existing soft block that has already been generated in the layout view, use the Edit Soft Blocks command. |
The introduction of this functionality means that the layout designer no longer needs to have write access to the schematic design to add or modify the properties that drive layout generation. As these properties are now controlled in the Configure Physical Hierarchy Window, a layout designer can define different physical configurations and view different physical implementation possibilities without changing the schematic view.
