The Physical tab shows the hard macros and all of its instances in your design with their full hierarchical names. This tab provides you with more detail than the Logical tab.
Hierarchy Window - Physical Tab
When you select a macro in this tab, the macro and all of its instances are selected in all other views where it appears.
In this view, you can assign or unassign an instance to a region or location from the right-click menu or drag an instance from this view to the ChipPlanner or PinEditor window.
You can also lock an assigned instance or unlock a locked instance in this view.
Note: You can only lock macros or instances that are currently assigned to a location.
