I have a pmos instance PM70<11:0> the sources are connected to vdd and the gates and drains are all connected together now the gates and sources are just floating but connected in to a single wire. 
So when I go to lvs the lvs thinks the bus is all unconnected as they are not connected to any other device. Yet in the layout I've shorted them together and as can be seen in the schematic they appear shorted together.
Is there a symbol to short together the bus? or terminate it or whatever is the correct technical term for this. As shown they (gate, drain) do not seem to short together for some reason.
