Thanks for all your hard work (and everyone else involved) to make such a useful, free tool.
I'm interested in RBA scripts for calculating and plotting effective local pattern density for a given layout and technology file. The technology file would specify the unit cell size for which to determine the local density and any models/filters for weighting the data within a cell.
The effective local pattern density information could then be used to help designers choose a better dummy fill density, or fed into an algorithm that optimizes their generation; all in order to improve process uniformity.
Perhaps something very basic could be put together using the clip tool, calc area tool, and tiling utility.
