Area Fill Documentation

Command Line

The area fill program is controlled from a command line. The complete options are detailed on the command line page.

Layer Operations

Often, the metal pattern on the mask/wafer is defined not by a single GDSII data layer but rather by a combination of layers. Area Fill supports the union of layers, subtraction of one layer from another and reversal of layers.

Tiling

One of area_fill's most useful functions is in calculating density by tiling a user defined window. For example, one may need to know the density over a 10 x 10 mm area in 200 x 200 um tiles.

Output

Area Fill's output is an ascii text file. If the user has specified tiling, then there will be a table output showing the area and center coordinate of each tile.
