The name of this signal.
finalinherited
naming → Naming
Controls the naming (and renaming) preferences of this signal in generated outputs.

parentModule ↔ Module?

getter/setter pairinherited

A Stream of LogicValueChanged events which triggers at most once per Simulator tick, iff the value of the Logic has changed from 0 to 1.
no setterinherited
previousValue → LogicValue?
The value of this signal before the most recent Simulator.tick had completed. It will be null before the first tick after this signal is created.
no setterinherited
reversed → Logic

no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sign → Logic
sign bit with '1' representing a negative number
finalinherited
srcConnection → Logic?
A LogicStructure never has a direct source driving it, only its elements do, so always returns null.
no setterinherited
structureName → String
Returns the name relative to the parentStructure-defined hierarchy, if one exists. Otherwise, this is the same as name.
no setterinherited
value → LogicValue
The current active value of this signal.
no setterinherited

no setterinherited
width → int
The number of bits in this signal.

Calculates the absolute value of a signal, assuming that the number is a two's complement.
inherited
and() → Logic
Unary AND.
inherited
clone({String? name}) → FloatingPoint
Creates a new LogicStructure with the same structure as this.
inherited
decr({Logic s(Logic p1)?, dynamic val = 1}) → Conditional
Decrements each element of elements using Logic.decr.
inherited
divAssign(dynamic val, {Logic s(Logic p1)?}) → Conditional
Divide-assigns each element of elements using Logic.divAssign.
inherited
eq(dynamic other) → Logic
Logical equality.
inherited
getRange(int startIndex, [int? endIndex]) → Logic
Returns a subset Logic. It is inclusive of startIndex, exclusive of endIndex.
inherited
gets(Logic other) → void
Connects this Logic directly to other.
inherited
gt(dynamic other) → Logic
Greater-than.
inherited
gte(dynamic other) → Logic
Greater-than-or-equal-to.
inherited
hasValidValue() → bool
Returns true iff the value of this signal is valid (no x or z).
inherited
incr({Logic s(Logic p1)?, dynamic val = 1}) → Conditional
Increments each element of elements using Logic.incr.
inherited
inject(dynamic val, {bool fill = false}) → void
Injects a value onto this signal in the current Simulator tick.
inherited
isFloating() → bool
Returns true iff all bits of the current value are floating (z).
inherited
isIn(List list) → Logic
Returns 1 (of width=1) if the Logic calling this function is in list. Else 0 (of width=1) if not present.
inherited
isNormal() → Logic
Return a Logic true if this FloatingPoint contains a normal number, defined as having mantissa in the range [1,2)

Multiply-assigns each element of elements using Logic.mulAssign.
inherited
neq(dynamic other) → Logic
Logical inequality.

Performs a Logic index based selection on an List of Logic named busList.
inherited
signExtend(int newWidth) → Logic
Returns a new Logic width width newWidth where new bits added are sign bits as the most significant bits. The sign is determined using two's complement, so it takes the most significant bit of the original signal and extends with that.

inherited
zeroExtend(int newWidth) → Logic
Returns a new Logic with width newWidth where new bits added are zeros as the most significant bits.
