How to add bus exports in Layout view.

[Kurt Landrus]

How do you add bus exports in a layout view so that they will match  
up with the
bus definitions in the schematic when running NCC?

here is the results of the summerize exports on a cell for both the  
schematic and layout views, The cell fails NCC, and I don't know how  
to label the input ports on the layout so that they match the bus  
port in the schematic.

=================================1179=================================
----- Exports on cell 'ALU_Control{lay}' -----
Input ports 'Op[0,1,2]' at (-160.0<=X<=-160.0, -64.0<=Y<=-50.0), same  
bus,
   connects to Metal-1
Output export 'Cin' at (77.0, 55.0) connects to Metal-1, Metal-2
Output ports 'G[0,1,2,3,4,5,6,7]' at (102.0<=X<=643.0,  
55.0<=Y<=63.5), same bus,
   connects to Metal-1, Metal-2
Power export 'vdd' at (-156.0, 32.5) connects to Metal-1
Ground export 'gnd' at (-158.0, -37.5) connects to Metal-1
=================================1180=================================
----- Exports on cell 'ALU_Control{sch}' -----
Input export 'Op[2:0]' at (-50.0, 28.0) connects to wire, bus
Output export 'Cin' at (40.0, 6.0) connects to wire, bus
Output export 'G[0:7]' at (52.0, -66.0) connects to wire, bus
