Glade Reference
This document describes the Python functions available from the Glade GUI. Argument types are shown as C++ types with default values where applicable, however all arguments are really python variables. All of the following functions are part of the ui class. There is a global pointer to the gui called cvar.guiptr. Therefore to use them , define you own variable e.g. gui=cvar.guiptr, then call as gui.OpenCellView(...)
Loads the PCell with name pcellName into the library libName. If the PCell already exists in the library, the action is ignored and returns true. If a cellView with the same name exists, it is deleted and is replaced by the PCell supermaster. Note that once a PCell is loaded into a library and that library is saved, it will remain a PCell, so there is no need to load it again (although it is harmless and you will just get warnings about the load being ignored). If the PCell cannot be created, it returns false.
Searches all libraries for instances of PCells with supermaster names given by name. Any instances found are updated with the (potentially new) python code for the PCell. This is necessary if you change the PCell code as there is no automatic updating performed.
Refresh the display. If force is false, the operation is put on the event queue, else it is immediately acted on.
Sets the maximum error count before errors are suppressed. THe default is 50. This is used in e.g. import commands where there may be many errors generated.
Gets the maximum error count.
Edit or view a file. If fileName is not specified, a file open dialog is displayed, else the f ile given by fileName will be opened. This function does nothing in non-graphics mode.
Execute the python script given by fileName.
Returns the current cellview being edited. If multiple cellviews are open, it returns the cellview of the current active window. There is also a top level python binding to this function, getEditCellView(). This function returns None in non-graphics mode.
Returns the library given by name.
Deletes a library.
Returns a dbObjList of all open libraries. There is also a top level python binding of the same name that returns a python list of open libraries.
Saves a library to disk as libName to the path libPath.
A library is a directory structure containing metadata in a glade.lib file, plus cellViews
in subdirectories where each subdirectory is the cell name, and the subdirectory contains files
each of which are the viewName of the cellView.
If verbose is true, detailed information on cells saved is written to the logfile.
If saveCells is true, library cells are saved; if false, then only the library tech
info is saved (to the glade.lib file in the library directory).

Compares two cellViews using an XOR operation using a simple non-tiled approach. This is good for cells of less than a few thousand transistors/shapes. The comparison is done for compareLayer; if this is set to -1 all layers in the cellViews are compared, else just the layer specified. If hier is false (the default), then the comparison is done at the top level only; if true then it is done hierarchically. The function returns 0 if the two cellViews are identical, -1 if an error occurred e.g. different number of layers in the cells, or different number of shapes (but see countShapes), or the number of differences found. If countShapes is false (the default) then the number of shapes may differ between the cells, but the XOR result must match.
Compares two cellViews using a tiled XOR operation. The comparison is done for compareLayer; if this is set to -1 all layers in the cellViews are compared. If hier is true (1), then the comparison is done hierarchically. The function returns 0 if the two cellViews are identical, -1 if an error occurred, or the number of differences found. If multiThreaded is true (the default), then the layout is tiled and run with maxThreads threads. If tileAuto is true (the default), an intelligent tiling algorithm is used, else tile widths and heights must be specified.

If outputTraps is true, outputs the resulting shapes as trapezoids rather than polygons (with holes using cutlines). size if true will size the output shapes by sizeBy microns.

If isHierNetList is true, then the netlist is treated as hierarchical and will be flattened with delimiter character delimiter and top cell name topCellName. If checkDeviceProps is true, device properties e.g. W, L or MOS devices are checked according to the tolerance specified byTolerance. The remainder of the parameters correspond to Gemini options.
Check a schematic cellView. errors is the number of errors found, or -1 if the cell could not be checked. If snapLabels is true, labels within snapDist of a wire will be snapped to the wire.
Check a symbol cellView. errors is the number of errors found, or -1 if the cell could not be checked.

Create a symbol cellView from the given cellView (normally a schematic). Returns true if successful. The symbol outline can be set by shape, and can be 0 (rectangular), 1 (triangular) or 2 (circular). pinSize sets the pi size in database units. snapGrid sets the snapping grid of the generated shapes
