In creating a net-list generic or Pads in the config file there is a little item called repack.
What it does is it Reslots or Re-redes's all your Slotted symbols.
If you have a large connector that you are using Slotted parts on and one is not connected to a net or some other minor thing that does not prevent netlisting.
DxDesigner can and will reslot it so that ground now goes to a pin that should have VDD on it or it may even split and add components so instead of one 100 pin connector you now have 5, one for each sheet.
I have been complaining about this since ViewLogic was all DOS. And I just got burned again.
I forgot that when ever I down load a new upgrade I have to edit the config files I did it for the pads netlister but forgot to do it for the generic.
Luckily I did a back up before doing the netlister.
