How to turn via merging off

michielqpi

Hi,

Is it possible to turn off via mering?

For example I have a 12 layer board. If I place a via from 5:7 and place one from 7:9 on it, it merges them together to 5:9. I don't want them to merge, so I can move both via's on their own.

I've tried changing the Pad-Pad Connect setting, but it won't change anything. THe via's are still merging.

Using:

  • OrCAD PCB Designer Professional 16.6-2015 S072
  • Windows 7 Professional 64-bit

Regards,

Michiel

    Solution: if you slide/move a merged via, select RMB --> Split stack. Now you can move the one you want.

    Hello,

    I would check the BB Via Stagger constraints to see what it is set to.  It will need to be set something greater than "0" to prevent them from stacking on top of each other during Slide.

    This can be checked and updated in Constraint Manager under the Physical Domain.  It would be best to update the value under the Physical Constraint Set so it applies across the entire design and it can be always overridden at the lower level objects, if necessary.

    Hope this helps,
