  • Publication number: 20150213181
    Abstract: This application discloses a computing system implementing one or more tools or mechanism configured to integrate different design stages, phases, or levels of abstraction by relating objects based on one or more of their characteristics, such as physical or electrical attributes, properties, references, or the like. The tools or mechanism can generate tags corresponding to characteristics of objects in one or more designs representing at least a portion of an electronic system. The tools or mechanism can link the objects in the one or more designs based, at least in part, on tags, and, in response to receiving a selection corresponding to a portion of the one or more designs, present information corresponding to at least another portion in the one or more designs associated with the selected portion based, at least in part, on the linked objects.
