1.19.3. Editing a Subsystem

You can double-click a Platform Designer subsystem in the Hierarchy tab to edit its contents in any tab. When you make a change, open tabs refresh their content to reflect your edit. You can change the level of a subsystem, or push the system into another subsystem with commands in the System View tab.
Note: You can only edit subsystems that a writable .qsys file preserves. You cannot edit systems that you create from composed _hw.tcl files, or systems that define instance parameters.
Follow these steps to edit a Platform Designer subsystem:
  1. Open a Platform Designer system that contains a subsystem.
  2. In the System View or Schematic tabs, use the Move Up, Move Down, Move to Top, and Move to Bottom toolbar buttons to navigate the system level you want to edit. Platform Designer updates to reflect your selection.
  3. To edit a system, double-click the system in the Hierarchy tab. The system opens and is available for edit in all Platform Designer views.
  4. In the System View tab, you can rename any element, add, remove, or duplicate connections, and export interfaces, as appropriate.
    Note: Changes to a subsystem affect all instances. Platform Designer identifies unsaved changes to a subsystem with an asterisk next to the subsystem in the Hierarchy tab.
