Xcif is a program that extracts the complete CIF
layout description from an ICD layout database. A cell is
known as a symbol in CIF. The current working directory must
be the project directory.
The unit of the parameters in the generated CIF file are
in centi microns.
With the origin mode (option -x, the default is no-origin
mode) the lower-left corner of the bounding box of a
sub-cell is used as the translation vector reference point.
Note that, if the bounding box information of sub-cells in
the database is incorrect, the sub-cell data can be
incorrectly placed.
Terminals are written with: "95 name w h x y
layer".
Labels are written with: "94 name x y
layer".
