Constructors

MaskRoundRobinArbiter(List<Logic> requests, {required Logic clk, required Logic reset})
Round Robin arbiter handles requests by granting each requestor and keeping record of requests already granted, in order to mask it until granting the turn of each request to start again

Properties

clk → Logic
The clock used for sequential elements.
latefinalinherited
count → int
The total number of requests and grants for this Arbiter.
latefinalinherited
definitionName → String
The definition name of this Module used when instantiating instances in generated code.
no setterinherited
grants → List<Logic>
Each element corresponds to an arbitration grant of the correspondingly indexed request passed at construction time.
latefinalinherited
hasBuilt → bool
Indicates whether this Module has had the build method called on it.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
inOuts → Map<String, Logic>
A map from inOut port names to this Module to corresponding Logic signals.
no setterinherited
inputs → Map<String, Logic>
A map from input port names to this Module to corresponding Logic signals.
no setterinherited
internalSignals → Iterable<Logic>
An Iterable of all Logics contained within this Module which are not an input or output port of this Module.
no setterinherited
name → String
The name of this Module.
finalinherited
outputs → Map<String, Logic>
A map from output port names to this Module to corresponding Logic signals.
no setterinherited
parent → Module?
The parent Module of this Module.
no setterinherited
requests → List<Logic>
Each element is the input pin for the correspondingly indexed request.
latefinalinherited
reserveDefinitionName → bool
If true, guarantees definitionName is maintained by a Synthesizer, or else it will fail.
finalinherited
reserveName → bool
If true, guarantees uniqueInstanceName matches name or else the build will fail.
finalinherited
reset → Logic
The reset used for sequential elements (active high).
latefinalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
signals → Iterable<Logic>
An Iterable of all Logics contained within this Module, including inputs, outputs, and internal signals of this Module.
no setterinherited
subModules → Iterable<Module>
An Iterable of all Modules contained within this Module.
no setterinherited
uniqueInstanceName → String
If this module has a parent, after build this will be a guaranteed unique name within its scope.
no setterinherited

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.
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
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.
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
Returns a pretty-print String of the heirarchy of all Modules within this Module.
inherited
inOut(String name) → Logic
Accesses the Logic associated with this Modules inOut port named name.
inherited
inOutSource(String name) → Logic
The original source provided to the creation of the inOut port name via addInOut or addInOutArray.
inherited
input(String name) → Logic

inherited
isInput(Logic signal) → bool
Returns true iff signal is the same Logic as the input port of this Module with the same name.
inherited
isOutput(Logic signal) → bool
Returns true iff signal is the same Logic as the output port of this Module with the same name.
inherited
isPort(Logic signal) → bool
Returns true iff signal is the same Logic as an input, output, or inOut port of this Module with the same name.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
output(String name) → Logic
