#### *Computation for Smoothing:*
When a macro overlaps with multiple gridcells, if any part of the module partially overlaps with the gridcell (either vertically, or horizontally), we set the top row (if vertical) or right column (if horizontal) to 0.

- Adding the Macro allocation congestion and Net routing congestion together for both Vertical and Horizontal congestion map
- Concat both vertical and horizontal congestion maps together.
- Take the top **5**% of the most congested gridcells **in the concatenation**, and average them out to get the final congestion cost.
