ARShift class

An arithmetic right-shift module.

Note that many simulators do not support the SystemVerilog generated by this module when it operates on LogicNets. The default shift operators on Logic will instead use swizzling to accomplish equivalent behavior.

Constructors

ARShift(Logic in_, dynamic shiftAmount, {String name = 'arshift'})
Calculates the value of in_ shifted right (arithmetically) by shiftAmount.

Properties

definitionName → String
The definition name of this Module used when instantiating instances in generated code.
no setterinherited
definitionParameters → List<SystemVerilogParameterDefinition>?
A collection of SystemVerilog SystemVerilogParameterDefinitions to be declared on the definition when generating SystemVerilog for this Module if generatedDefinitionType is DefinitionGenerationType.standard.

no setterinherited
inputs → Map<String, Logic>
A map from input port names to this Module to corresponding Logic signals.

no setterinherited
signed → bool
Whether or not this gate operates on a signed number.
finalinherited
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
width → int
The width of the output for this operation.
