When complete,
you can load the Results Database (GDSII or OASIS) file in your layout editor
of choice to review Ground Rule violations. Note the Ground Rule violations
will have layer IDs that correspond to the layer that contains the layer. The
Datatype is numbered starting from 1 and corresponds to the Ground Rule violation
in the Design guide.
Example:
-
SEAM (709/727) in
the layout design has violations for minimum width and minimum space design
rules. The output layers for these violations will be 709/1 and 709/3,
respectively, where Datatypes 1 & 3 correspond to the minimum width and
minimum space rules, respectively, in the Design guide.
If
your Results Database is ASCII, you can load the file in Caliber RVE or
KLayout->Tools->Shapes To Markers->Hierarchical.
