VHDL Conventions

Enterprise Architect supports round-trip engineering of VHDL, where these conventions are used.

Stereotypes

Stereotype	Applies To	See also
architecture	Class Corresponds To: An architecture.
asynchronous	Method Corresponds To: An asynchronous process.
configuration	Method Corresponds To: A configuration.
enumeration	Inner Class Corresponds To: An enumerated type.
entity	Interface Corresponds To: An entity.
part	Attribute Corresponds To: A component instantiation.
port	Attribute Corresponds To: A Port.
signal	Attribute Corresponds To: A signal declaration.
struct	Inner Class Corresponds To: A record definition.
synchronous	Method Corresponds To: A synchronous process.
typedef	Inner Class Corresponds To: A type or subtype definition.

Tagged Values

Tag	Applies To	See also
isGeneric	Attribute (port) Corresponds To: The 'port' declaration in a generic interface.
isSubType	Inner Class (typedef) Corresponds To: A subtype definition.
kind	Attribute (signal) Corresponds To: The signal kind (such as 'register', 'bus').
mode	Attribute (Port) Corresponds To: The Port mode ('in', 'out', 'inout', 'buffer', 'linkage').
portmap	Attribute (part) Corresponds To: The generic/Port map of the component instantiated.
sensitivity	Method (synchronous) Corresponds To: The 'sensitivity' list of a synchronous process.
type	Inner Class (typedef) Corresponds To: The 'type' indication of a 'type' declaration.
typeNameSpace	Attribute (part) Corresponds To: The 'type' namespace of the instantiated component.

VHDL Toolbox Pages

Access

To model a VHDL design, drag icons from the VHDL toolbox pages and drop them on your diagram.

Ribbon	Design > Diagram > Toolbox : > Specify 'VHDL Constructs' in the 'Find Toolbox Item' dialog
Keyboard Shortcuts	Ctrl+Shift+3 : > Specify 'VHDL Constructs' in the 'Find Toolbox Item' dialog
Other	You can display or hide the Diagram Toolbox by clicking on the or icons at the left-hand end of the Caption Bar at the top of the Diagram View.

VHDL Toolbox Page

Item	Action
Architecture	Defines an architecture to be associated with a VHDL entity. An architecture-stereotyped Class element.
Entity	Defines a VHDL entity to contain the Port definitions. An entity-stereotyped interface element.
Enumeration	Defines an Enumerated Type. An Enumeration element.
Struct	Defines a VHDL record. A struct-stereotyped Class element.
Typedef	Defines a VHDL type or subtype. A typedef-stereotyped Class element.

VHDL Features Toolbox Page

Item	Action
Part	Defines a VHDL component instantiation. A part-stereotyped attribute.
Port	Defines a VHDL Port. A port-stereotyped attribute.
Signal	Defines a VHDL signal. A signal-stereotyped attribute.
Procedure	Defines a VHDL process: Concurrent - An asynchronous-stereotyped method Sequential - A synchronous-stereotyped method Configuration - An configuration-stereotyped method
