API reference - Class LEFDEFReaderConfiguration

Notation used in Ruby API documentation

Module: db

Description: Detailed LEF/DEF reader options

This class is a aggregate belonging to the LoadLayoutOptions class. It provides options for the LEF/DEF reader. These options have been placed into a separate class to account for their complexity. This class specifically handles layer mapping. This is the process of generating layer names or GDS layer/datatypes from LEF/DEF layers and purpose combinations. There are basically two ways: to use a map file or to use pattern-based production rules.

To use a layer map file, set the map_file attribute to the name of the layer map file. The layer map file lists the GDS layer and datatype numbers to generate for the geometry.

The pattern-based approach will use the layer name and attach a purpose-dependent suffix to it. Use the ..._suffix attributes to specify this suffix. For routing, the corresponding attribute is routing_suffix for example. A purpose can also be mapped to a specific GDS datatype using the corresponding ..._datatype attributes. The decorated or undecorated names are looked up in a layer mapping table in the next step. The layer mapping table is specified using the layer_map attribute. This table can be used to map layer names to specific GDS layers by using entries of the form 'NAME: layer-number'.

If a layer map file is present, the pattern-based attributes are ignored.

Detailed description

_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.
