Groundwall of Via
The DFE rule checks for a proper placement of ground vias and ground wall regions.
- Net: Select a target ground net group.
- Groundwall Ratio (%): Assign ground vias allowable coverage ratio.
- Distance: Assign a clearance between via and board edges.
- Via Coverage
- Default Via Coverage: Use the region defined in the Input Dialog.
- Via Coverage: User-defined coverage.
- Except Net: Exclude areas from calculating the board outline area if copper exists inside the board outline area.
- Except Component: Exclude component areas from calculating the board outline area if the component exists inside the board outline area. (PollEx DFE checks only those components within the distance when the Distance option is selected and the distance value is entered.)
- Except Hole: Exclude hole areas from calculating the board outline area if the hole exists inside the board outline area.
