Methods

addSubInterface<PairInterfaceType extends PairInterface>(String name, PairInterfaceType subInterface, {bool reverse = false, String uniquify(String original)?}) → PairInterfaceType
Registers a new subInterface on this PairInterface, enabling a simple way to build hierarchical interface definitions.
inherited
clone() → Axi4AwChannelInterface
Copy constructor.
override
conditionalDriveOther(Interface<PairDirection> other, Iterable<PairDirection> tags) → Conditional
Makes this conditionally drive interface signals tagged with tags on other.
inherited
conditionalReceiveOther(Interface<PairDirection> other, Iterable<PairDirection> tags) → Conditional
Makes this signals tagged with tags be driven conditionally by other.
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 this drive interface signals tagged with tags on other.
inherited
getPorts([Iterable<PairDirection>? tags]) → Map<String, Logic>
Returns all interface ports associated with the provided tags as 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 this signals tagged with tags be driven by other.
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 name if it exists, otherwise null.
