Hi Everyone
Please excuse me if this is an old subject.
I have thru-hole vias connected to a gnd plane on the top layer. There
is +5v plane on the bottom side of the PCB. There are no clines
connected to the vias so when ever I move the gnd plane, the vias are
now associated to the +5v plane. I now have to move the +5v plane before
moving back the gnd plane if I want to keep these vias associated to
gnd. This is really a bad problem on a multi-layer board with different
planes on different layers and when I have vias that I want to keep
associated to different nets.
Is there any way to keep the vias associated to the original nets
without connecting clines to them? Cadence did not have an answer.
Thanks for any suggestions
