db_Techfile

The db_Techfile class contains technology related parameters, in particular the layers used in a design. A db_Techfile object does not normally need to be created as creating a library will initialise a techfile associated with that library. For example:

lib = library("myLib")

tech = lib.tech()

int tech.techLoad(char *fileName)

Loads a techfile specified by fileName.

int tech.techSave(char *fileName)

Saves a techfile to fileName.

Layer related operations

Layers are signed 16 bit integers and map to layer-purpose pairs. A layer number of -1 signifies an invalid layer.

bool tech.isSelectable(int layer)

Returns 1 if layer is selectable, else returns 0.

tech.selectable(int layer, bool sel)

Sets a layer selectable is sel is nonzero.

bool tech.isVisible(int layer)

Returns 1 if layer is visible, else returns 0.

tech.visible(int layer, bool vis)

Sets a layer visible is vis is nonzero.

bool tech.isUsed(int layer)

Returns 1 if layer is used, else returns 0.

tech.setUsed(int layer, bool used)

Sets a layer used if used is nonzero.

int tech.color(int layer)

Returns a 32 bit int of the layer color in rgba format.

tech.color(int layer, int color)

Sets a layer color. color is a 32 bit integer in rgba format.

tech.setLayerName(int layer, char *name)

Sets a layer's name.

char * tech.getLayerName(int layer)

Gets the layer's name.

tech.setLayerPurpose(int layer, char *name)

Sets a layer's purpose.

char * tech.getLayerPurpose(int layer)

Gets the layer's purpose.

char * tech.getLayerPurposePair(int layer)

tech.setLayerGdsLayer(int layer, int gdsNum)

Sets a layer's GDS number to gdsNum.

int tech.getLayerGdsLayer(int layer)

int tech.getLayerNum(char name, char purpose, int warn=1)

Gets a layer number if one exists with the specified name and purpose. If it does not exist a warning is given unless warn is set to 0.

int tech.createLayer(char name, char purpose)

Creates a layer in the techfile with the specified name and purpose. Returns the layer number or -1 if the layer cannot be created.
