[PCB_FORUM] Re: same net rules

Patrick,
I think it is available even in a lower tool than Performance:
setup-> constrains->design constrains->soldermask to soldermask

Dave,
they do if same net DRC is switched on, but:
- I cannot assign different values for 'same net' and 'different net'
- I see occasionally unwanted and annoying DRCs 'Line to Line Spacing' when clines overlaps (intentionally)

Hi all,

I think I do understand the question since I also miss such feature.

Problem stated:
 - to not to have Via too close to SMD pin

Partial Solution:
 - enable same net DRC (problem is that it checks all other rules and often
creates many unwanted DRCs)

Other possibility
 - set a rule for "Solder mask to Solder mask" spacing assuming that Vias
are not covered (problem is that this is one global rule for a whole design)

regards,
Robert

Is there no way in Allegro to have the same net rules apply only to certain rules? The one I always need is via to smd pin, but I would not want all the rest of the rules to have same net application.
