I need to put Dummy net on NC pin of a LED. But when i put Dummy net and try to assign to that pin it is showing "cannot assign dummy net to that pin".
I need to put dummy net on that pin for heat dissipation.
Thanks & Regards,
What I do (16.6) is add a short net to a pin in the schematic. Then in the constraint manager I create a dummy CSet and create net properties such as spacing. Once the CSet is created i assign the short net to the Cset.
I do this alot for electric spacing on pins attached to packages that are design as a non bonded (internally) pins that are designed such to meet electrical clearances between to high voltage pins. This way I don't have to wave DRC's (I don't like any DRC's even waved ones).
That's actually the best way IMHO to do it -- as you point out you can class these nets appropriately.
