Description copied from class: Geometry

Abstract method called before hierarchy traversal

Specified by:

start in class Geometry

done

protected void done()

Description copied from class: Geometry

Abstract method called after traversal

Specified by:

done in class Geometry

writeCellGeom

protected void writeCellGeom(Geometry.CellGeom cellGeom)

Method to write cellGeom

Specified by:

writeCellGeom in class Geometry

mergeGeom

protected boolean mergeGeom(int hierLevelsFromBottom)

Method to determine whether or not to merge geometry.

Overrides:

mergeGeom in class Geometry

includeGeometric

protected boolean includeGeometric()

Method to determine whether or not to include the original Geometric with a Poly

Overrides:

includeGeometric in class Geometry

writePoly

protected void writePoly(PolyBase poly,
             int layerNumber,
             int layerType)

writeNodable

protected void writeNodable(Nodable no)

buildUniqueNames

public static void buildUniqueNames(Cell cell,
                    java.util.Map<Cell,java.lang.String> cellNames,
                    int maxLen,
                    boolean upperCase)

Recursive method to add all cells in the hierarchy to the hashMap with unique names.

Parameters:

cell - the cell whose nodes and subnode cells will be given unique names.

cellNames - a hashmap, key: cell, value: unique name (String).

makeUniqueName

public static java.lang.String makeUniqueName(Cell cell,
                              java.util.Map<Cell,java.lang.String> cellNames,
                              int maxLen,
                              boolean upperCase)

getCellNames

public java.util.Map<Cell,java.lang.String> getCellNames()

Get the name map. GDS output may mangle cell names because of all cells occupy the same name space (no libraries).

outputDouble

public void outputDouble(double data)

Method to write a GDSII representation of a double. New conversion code contributed by Tom Valine .

Parameters:

data - the double to process.
