Layer Filtering Module

The group of entries below the file path controls layer filtering and aliasing. These are optional and can be ignored if no layer manipulations are needed.

The module contains the following controls:

Layer List text area
The Layer List can be set to a space-separated list of layer names. Each layer name is expected to match an effective layer name in the file being read. For file types such as GDSII that designate layers with layer/datatype integers, either the hex encoding or decimal form can be used, with wildcarding accepted. The Layer List is ignored unless one of the following two check boxes is selected.

Layers Only check box
If this box is checked, only the layers listed in the Layer List will be read from the source.

Skip Layers check box
This box can be checked if the Layers Only box is unchecked. When checked, layers listed in the Layer List will be ignored in the source. All layers except those listed will be read.

Layer Aliases text area
This provides a means for converting layers found in input from the source to a different layer when written to output. The entered text contains zero of more space-separated text tokens in the form
oldname=newname
The oldname is a layer name consistent with the source format. For GDSII and OASIS, either hex or decimal encoding is accepted. The newname is the destination layer consistent with the output format. Again, gor GDSII and OASIS either the hex or decimal forms may be used. There should be no space between the names (or in the names) and the equal sign `=' separator.
