DEF (Design Exchange Format) is a recent interchange format for CAD systems.
It is often combined with LEF (Library Exchange Format) files.
For more information on reading and writing DEF or LEF, see
Section 3-9-2 and
Section 3-9-3,
respectively.
DEF options are controlled with the DEF Preferences
(in menu File / Preferences..., "I/O" section, "DEF" tab).
This dialog controls whether DEF reads physical and/or logical information.
If a type of interconnect is not checked, the DEF input reader ignores those arcs.
