Virtual Connections in Assura LVS
If you have two wires on a layout that are unconnected but will be connected together in a higher level then place a pin on both wires. When running Assura LVS you need to set some further options. Enable "View avParameters" and then click "Modify avParameters...". Find the "joinPins" option, enable it ("Use in run") and set it to "Top". Click OK to close the avParameters window. Now enable "View Additional Functions" followed by "Use joinableNet Function". Now click "Modify joinableNet Function...". In the new window enable "root cell?" then add your net to the "Net Names to Join" box and click "Add to Command List (below)" to add it. Click OK to close the joinableNet window and then run LVS as normal.
