Methods

addInOut(String name, Logic source, {int width = 1}) → LogicNet
Registers a signal as an inOut to this Module and returns an inOut port that can be consumed inside this Module.
inherited
addInOutArray(String name, Logic source, {List<int> dimensions = const [1], int elementWidth = 1, int numUnpackedDimensions = 0}) → LogicArray
Registers and returns an inOut LogicArray port to this Module with the specified dimensions, elementWidth, and numUnpackedDimensions named name.
inherited
addInput(String name, Logic source, {int width = 1}) → Logic
Registers a signal as an input to this Module and returns an input port that can be consumed.
inherited
addInputArray(String name, Logic source, {List<int> dimensions = const [1], int elementWidth = 1, int numUnpackedDimensions = 0}) → LogicArray
Registers and returns an input LogicArray port to this Module with the specified dimensions, elementWidth, and numUnpackedDimensions named name.
inherited
addInterfacePorts<InterfaceType extends Interface<TagType>, TagType extends Enum>(InterfaceType source, {Iterable<TagType>? inputTags, Iterable<TagType>? outputTags, Iterable<TagType>? inOutTags, String uniquify(String original)?}) → InterfaceType
Connects the source to this Module using Interface.connectIO and returns a copy of the source that can be used within this module.
inherited
addOutput(String name, {int width = 1}) → Logic
Registers an output to this Module and returns an output port that can be driven by this Module or consumed outside of it.
inherited
addOutputArray(String name, {List<int> dimensions = const [1], int elementWidth = 1, int numUnpackedDimensions = 0}) → LogicArray
Registers and returns an output LogicArray port to this Module with the specified dimensions, elementWidth, and numUnpackedDimensions named name.
inherited
addPairInterfacePorts<InterfaceType extends PairInterface>(InterfaceType source, PairRole role, {String uniquify(String original)?}) → InterfaceType
Connects the source to this Module using PairInterface.pairConnectIO and returns a copy of the source that can be used within this module.
inherited
addTypedInOut<LogicType extends Logic>(String name, LogicType source) → LogicType
Registers a signal as an inOut to this Module and returns an inOut port that can be consumed inside this Module. The type of the port will be LogicType and constructed via Logic.clone, so it is required that the source implements clone functionality that matches the type and properly updates the Logic.name as well.
inherited
addTypedInput<LogicType extends Logic>(String name, LogicType source) → LogicType
Registers a signal as an input to this Module and returns an input port that can be consumed. The type of the port will be LogicType and constructed via Logic.clone, so it is required that the source implements clone functionality that matches the type and properly updates the Logic.name as well.
inherited
addTypedOutput<LogicType extends Logic>(String name, LogicType logicGenerator({String name})) → LogicType
Registers an output to this Module and returns an output port that can be driven by this Module or consumed outside of it. The type of the port will be LogicType and constructed via logicGenerator, which must properly update the name of the generated LogicType as well.
inherited
build() → Future<void>
Builds the Module and all subModules within it.
inherited
generateSynth() → String
Returns a synthesized version of this Module.
inherited
hierarchy() → Iterable<Module>
Returns an Iterable of Modules representing the hierarchical path to this Module.
inherited
hierarchyString([int indent = 0]) → String

inherited
inputSource(String name) → Logic
The original source provided to the creation of the input port name via addInput or addInputArray.

Invoked when a nonexistent method or property is accessed.
inherited
output(String name) → Logic
Accesses the Logic associated with this Modules output port named name.
inherited
toString() → String
A string representation of this object.
inherited
tryInOut(String name) → Logic?
Provides the inOut named name if it exists, otherwise null.
