Abstract

Disclosed are methods, systems, and articles of manufacture for implementing dynamic maneuvers within virtual hierarchies of an electronic design. These techniques identify or generate a plurality of figure groups at one or more virtual hierarchies in a layout portion and receive a request to descend into or ascend from a figure group at a virtual hierarchy of the one or more virtual hierarchies. In response to the received request, these techniques update a layout view into an updated layout view at least by exposing layout design details in the figure group for native editing according to the request to descend into or ascend from the figure group and optionally synchronize a corresponding schematic design view according to the updated layout view.
