API reference - Class LoadLayoutOptions

AddToCell

Signature: [static,const] LoadLayoutOptions::CellConflictResolution AddToCell

Description: Add content to existing cell

This is the mode use in before version 0.27. Content of new cells is simply added to existing cells with the same name. Before version 0.29.2, this mode also merged instances, rendering it difficult to merge two identical cell hierarchies. Since version 0.29.2, no instance duplicates are generated. Instead only new instances are added to existing cells. With this feature in place, it is safe to merge two identical cell hierarchies stored in different files using AddToCell mode. In that application, the shapes and layers of the layouts are combined, but the cell hierarchy stays identical.

Python specific notes:
The object exposes a readable attribute 'AddToCell'. This is the getter.

OverwriteCell

Signature: [static,const] LoadLayoutOptions::CellConflictResolution OverwriteCell

Description: The old cell is overwritten entirely (including child cells which are not used otherwise).

Python specific notes:
The object exposes a readable attribute 'OverwriteCell'. This is the getter.

RenameCell

Signature: [static,const] LoadLayoutOptions::CellConflictResolution RenameCell

Description: The new cell will be renamed to become unique.

In this mode, two files are are combined rendering independent cell hierarchies coming from the original files. Cells may be renamed however. Also, new top cells will appear after merging a file into the layout using RenameCell mode.

Python specific notes:
The object exposes a readable attribute 'RenameCell'. This is the getter.

SkipNewCell

Signature: [static,const] LoadLayoutOptions::CellConflictResolution SkipNewCell

Description: The new cell is skipped entirely (including child cells which are not used otherwise).

Python specific notes:
The object exposes a readable attribute 'SkipNewCell'. This is the getter.

_const_cast

Signature: [const] LoadLayoutOptions ptr _const_cast

Description: Returns a non-const reference to self.

Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects.

This method has been introduced in version 0.29.6.

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

assign

Signature: void assign (const LoadLayoutOptions other)

Description: Assigns another object to self

cell_conflict_resolution

Signature: [const] LoadLayoutOptions::CellConflictResolution cell_conflict_resolution

Description: Gets the cell conflict resolution mode

mag_dbu

Signature: [const] double mag_dbu

This property has been added in version 0.26.2.

Python specific notes:
The object exposes a readable attribute 'mag_dbu'. This is the getter.

mag_dbu=

Signature: void mag_dbu= (double dbu)

Description: Specifies the database unit which the reader uses and produces

The database unit is the final resolution of the produced layout. This physical resolution is usually defined by the layout system - GDS for example typically uses 1nm (mag_dbu=0.001). All geometry in the MAG file will first be scaled to mag_lambda and is then brought to the database unit.

This property has been added in version 0.26.2.

Python specific notes:
The object exposes a writable attribute 'mag_dbu'. This is the setter.

mag_keep_layer_names=

Signature: void mag_keep_layer_names= (bool keep)

See mag_keep_layer_names? for a description of this property.

This method has been added in version 0.26.2.

Python specific notes:
The object exposes a writable attribute 'mag_keep_layer_names'. This is the setter.

mag_keep_layer_names?

Signature: [const] bool mag_keep_layer_names?

Description: Gets a value indicating whether layer names are kept

When set to true, no attempt is made to translate layer names to GDS layer/datatype numbers. If set to false (the default), a layer named "L2D15" will be translated to GDS layer 2, datatype 15.

This method has been added in version 0.26.2.

Python specific notes:
The object exposes a readable attribute 'mag_keep_layer_names'. This is the getter.

mag_lambda

Signature: [const] double mag_lambda

Description: Gets the lambda value

See mag_lambda= method for a description of this attribute.

This property has been added in version 0.26.2.

Python specific notes:
The object exposes a readable attribute 'mag_lambda'. This is the getter.

mag_lambda=

Signature: void mag_lambda= (double lambda)

Description: Specifies the lambda value to used for reading

The lambda value is the basic unit of the layout. Magic draws layout as multiples of this basic unit. The layout read by the MAG reader will use the database unit specified by mag_dbu, but the physical layout coordinates will be multiples of mag_lambda.

This property has been added in version 0.26.2.

Python specific notes:
The object exposes a writable attribute 'mag_lambda'. This is the setter.

mag_layer_map

mag_layer_map=

Signature: void mag_layer_map= (const LayerMap map)

Description: Sets the layer map

This sets a layer mapping for the reader. Unlike mag_set_layer_map, the 'create_other_layers' flag is not changed.

This method has been added in version 0.26.2.

Python specific notes:
The object exposes a writable attribute 'mag_layer_map'. This is the setter.

mag_library_paths

Signature: [const] string[] mag_library_paths

Description: Gets the locations where to look up libraries (in this order)

mag_library_paths=

Signature: void mag_library_paths= (string[] lib_paths)

Description: Specifies the locations where to look up libraries (in this order)

The reader will look up library reference in these paths when it can't find them locally. Relative paths in this collection are resolved relative to the initial file's path. Expression interpolation is supported in the path strings.

This property has been added in version 0.26.2.

Python specific notes:
The object exposes a writable attribute 'mag_library_paths'. This is the setter.
