Technology File

The following nodes and classes are read from the Cadence ASCII technology file.

include
This node contains a string, which is a path to another Lisp file. That file will be opened and read.

comment
This node is ignored.

controls
This class contains the following nodes.
techParams
This node is ignored.
techPermissions
This node is ignored.

layerDefinitions
This class contains the following nodes.
techLayers
A new layer is created in the Xic layer table for each entry with a layer number in the range 0-127. The abbreviation field is ignored. The layer ``long name'' will be assigned the layer name, if it is more that four characters long. New layers are created in the order of appearance.
techPurposes
This node is ignored.
techLayerPurposePriorities
This will reorder the layers already in the Xic layer table in the order given. Only layers with the purpose ``drawing'' are considered. This should appear after techLayers.
techDisplays
This will assign the colors and fill patterns to layers that exist in the Xic layer table. Only entries with purpose `` drawing'' are considered. This references the internal packet, color, and stipple lists created from the design resource nodes.
techLayerproperties
This node is ignored.

layerRules
This class contains the following nodes.
viaLayers
The conducting layers are assigned the Conductor attribute. The via layer is assigned the Via and DarkField attributes.
equivalentLayers
This node is ignored.
streamLayers
A GDSII import/export mapping is applied for each layer given.
