How can I push an instance down one level in the design hierarchy

aaronginn

Synthesis is generating a gate-level netlist with an instance (INV123) at the top level of hierarchy. I want to push that instance down one level in the design hierarchy into a module called "DIG123". Is there a way to do this? Using Innovus (21.xx).

TIA.

  • Hi,

    you will first need to create an instance group with the createInstGroup command, then add instances to it with addInstToInstGroup.
    You can then create a new hierarchy for this group with createLogicHierarchy.
    Please refer to the tool command reference for more details on using these commands.

    Note: These are the legacy UI commands, if you are using Stylus (Common UI), use the following command to find the correct command mapping : get_common_ui_map

    Thanks. What if the hierarchical module already exists? I don't want to create a new module. I want to push one instance down from the top level of the design into an existing module.

    OK. I think I discovered how to do this. Thanks for the help.
