Abstract

A system and method for synchronizing the display and edit of a plurality of connected layouts or documents within a single display. A first document or plurality of elements may be displayed as active and a second document or plurality of elements may be displayed as non-active background in a first window. The second document or plurality of elements may be displayed as active and the first document or plurality of elements may be displayed as non-active background in a second window. Any action detected in either window may be displayed in the other window. Upon selection of any active element or predefined net list, the elements physically or logically connected to the selected element or net list may be highlighted in the active documents, listed, or otherwise identified. An inter-document net list may identify connections between existing net lists in multiple documents.
