Export DEF in IC61

Hi,

IC61 version 6.1.5.500.6

I am uisng  VXL

Guuys, I need some help to find out how can I define VDD,VSS as a special nets in exported DEF file in IC61?

Setting them as "power" and "ground" doesn't work.

Interesting thing is when I am routing them using Create Wire or from Navigator I don't get them SPECIAL, but when I route them by using Create->Shape->Geometrical Wire I DO GET THEM as SPECIAL.

The only differences I could find is my Create Wire net had Route Net Name = VDD,Geometrical Shape net had Net Name=VDD.

Did somebody have similar problem ? Does it  matter what routing strategy I am using and how in any case define SPECIAL net in IC61?

 

Many thanks,

Eduard Raines
