Methods
-
addSubInterface<
PairInterfaceType extends PairInterface> (String name, PairInterfaceType subInterface, {bool reverse = false, String uniquify(String original)?}) → PairInterfaceType -
Registers a new
subInterfaceon this PairInterface, enabling a simple way to build hierarchical interface definitions.inherited -
clone(
) → PairInterface -
Creates a new Interface with the same ports as
this.inherited -
conditionalDriveOther(
Interface< PairDirection> other, Iterable<PairDirection> tags) → Conditional -
Makes
thisconditionally drive interface signals tagged withtagsonother.inherited -
conditionalReceiveOther(
Interface< PairDirection> other, Iterable<PairDirection> tags) → Conditional -
Makes
thissignals tagged withtagsbe driven conditionally byother.inherited -
connectIO(
Module module, Interface srcInterface, {Iterable< PairDirection> ? inputTags, Iterable<PairDirection> ? outputTags, Iterable<PairDirection> ? inOutTags, String uniquify(String original)?}) → void -
Calls Interface.connectIO for ports of this interface as well as
hierarchically for all subInterfaces.
inherited
-
driveOther(
Interface< PairDirection> other, Iterable<PairDirection> tags) → void -
Makes
thisdrive interface signals tagged withtagsonother.inherited -
getPorts(
[Iterable< PairDirection> ? tags]) → Map<String, Logic> -
Returns all interface ports associated with the provided
tagsas a Map from the port name to the Logic port.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
pairConnectIO(
Module module, Interface< PairDirection> srcInterface, PairRole role, {String uniquify(String original)?}) → void -
A simplified version of connectIO for PairInterfaces where by only
specifying the
role, the input and output tags can be inferred.inherited -
port(
String name) → Logic -
Accesses a port named
name.inherited -
receiveOther(
Interface< PairDirection> other, Iterable<PairDirection> tags) → void -
Makes
thissignals tagged withtagsbe driven byother.inherited -
setPorts(
List< Logic> ports, [Iterable<PairDirection> ? tags]) → void -
Adds a collection of ports to this Interface, each associated with all
of
tags.inherited -
toString(
) → String -
A string representation of this object.
inherited
-
tryPort(
String name) → Logic? -
Provides the port named
nameif it exists, otherwisenull.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
