Connecting the Polygon to a Net
A Polygon can be attached to a net. Select the required net in the Connect to Net drop-down in the Polygon Pour dialog. The Polygon pour will connect to each pad on this net that is
found within the outline of the Polygon. How the polygon connects to the
pads is determined by the applicable Polygon Connect Style design rule. The clearance between the polygon and objects belonging to other nets is determined by the applicable Electrical Clearance design rule.
How the polygon treats objects on the same net, such as routing tracks, is determined by the option selected in the Pour Over drop-down:
- Pour Over All Same Net Objects - choose this option if you want the Polygon to automatically connect to all objects on the same net as the pour.
- Pour Over Same Net Polygons Only - choose this
option (default) if you want the Polygon to automatically connect to
only Polygon objects inside its boundary, which are attached to the same
net.
- Don't Pour Over Same Net Objects - choose this
option if you specifically do not wish the Polygon pour to connect to
any other, non-pad objects on this (or any other) net.
