Add Via Shape - Package Design

package design

 From BGA pin as well from Die bump we will be bringing vias to internal core layers. In the build-up layers there will be lot of same net vias. We would like to add a shape for the multiple vias (same net) to connect. Once I select a vias (same net) and click add shape it should add a shape to those selected vias and assign a net name of the selected vias. Attached a picture for ref.

  •  It is fortunate the shape you wish to lay on top of the vias is symmetrical as is the groupings of the pins, makes the task easier.

    Use the centers of the voids in the plane-shape as centers for placement of your overlay-shapes, with a simple calculation to determine orientation of the shapes as necessary.
