Methods

addInOut(String name, Logic source, {int width = 1}) → LogicNet

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
addOutput(String name, {int width = 1}) → Logic
Registers an output to this Module and returns an output port that can be driven.
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.
