Dennis,

To be honest I have never implemented it in the schematic and/or symbol. I have 
used it on vias to short two nets together even multiple vias as per figure 7. 
I have also used a static shape between two pads but I think I did not extend 
the shape to the center of the pad I was shorting to and the net short property 
was added to that pin "not the shape". I will dig up some old designs if you 
need more information on how I implemented it.

So I follow the doc when building by symbol but I have pad to pad errors 
because I have via pads inside of a larger pad.  I see on figure 3 of the ap 
note they have pad to pad errors also.   So do I leave these errors or am I 
missing a step?  Thanks! -DC

Hi Everyone,
                Can I ask how to properly short two or more grounds at a common 
point using Cadence Allegro 16.X and Design Entry HDL?  Thanks for any and all 
ideas! DC
