Fair enough, but how would you get rid of the DRC in that example?

True - but anything could short to that pin and "Not be Reported". I am not the 
only one who works on my boards so I tend to constrain so it cannot be wrong by 
lack of knowledge.
Hope that was politically correct.

Not in the example I gave, it only allows the DRC for that pin, not the whole 
net.

My guess is that you could put a "No_Drc" property on the pin.

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
