Auto Height Vias
One via definition can create vias that stop at different levels
V15 extends the capabilty of vias and the via technogy layers. All the vias going down for one level can individually auto sense metal and stop on the level where the via touchs metal. This allows one via tech layer to hold and organize all the vias orginiating from the same level. This is useful for projects such as RFIC's with MIMcaps.
