pyVHDLModel.Declaration

This module contains parts of an abstract document language model for VHDL.

Classes

• EntityClass: An EntityClass is an enumeration. It represents a VHDL language entity class (entity, label, …).

• Attribute: Represents an attribute declaration.

• AttributeSpecification: Represents an attribute specification.

• Alias: ModelEntity is the base-class for all classes in the VHDL language model, except for mixin classes (see multiple
