Via being flagged by DRC as 'Net Antennae'
« on: October 10, 2016, 06:33:09 pm »
Hello everyone,

Does anyone have any tips for getting the DRC to not call a via a net Antennae?  My layout is error free except for a single via which Altium has decided is a net antenna.  I'm running the latest 16.1 release and it has no problems with my other vias.  I've tried coming at it from different directions, making sure the tracks don't touch in the via area, etc and I can't get it to work.  If I delete the via I get an un-routed net error and more net Antennae errors since the tracks don't connect to anything without the via.

Edit:  A little more complaining and re-drawing and it now works.  No idea why, so I still would love an explanation if anyone knows what causes this type of behavior.

Delete it and replace?

Also, set a PolygonConnect rule, IsVia, direct connect.  Shouldn't affect the present problem, but it looks better. ;)

your blue trace does not go all the way to the center of the via.

but its suppose to already electrically connected to the via, Altium should not complain it as a stray antenna, its a bug.
