I Fixed the Bus errors, after I looked closer, it wasn't complaining about the Bus naming, but the inputs were connected to the wrong input of my gates, for example to input A, instead of input B. Mentor Graphics has a feature that treats inputs of gates the same so it will resolce errors like this when doing LVS. Is there any settings in Electric that will correct for these type of errors? Also now that i got the wiring corrected, I am down to the following error complaining that my parts don't match, and i'm not sure how to get it to pass NCC now, any suggestions?

How do you add bus exports in a layout view so that they will match

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.

----- Exports on cell 'ALU_Control{lay}' -----
Input ports 'Op[0,1,2]'
Output export 'Cin'
Output ports 'G[0,1,2,3,4,5,6,7]'

----- Exports on cell 'ALU_Control{sch}' -----
Input export 'Op[2:0]'
Output export 'Cin'
Output export 'G[0:7]'

This is the correct way to do it. There are no layout busses, so you just create individual exports that match the bus entry names.

If NCC is failing, then perhaps there is some other problem than export name matching. You may want to send a small example to me.
