Properties

arrayIndex → int?
If this is a part of a LogicArray, the index within that array. Othwerise, returns null.
no setterinherited
bit → LogicValue
The current active value of this signal if it has width 1, as a LogicValue.
no setterinherited
changed → Stream<LogicValueChanged>
A Stream of LogicValueChanged events which triggers at most once per Simulator tick, iff the value of the Logic has changed.

latefinalinherited
elements → List<Logic>

unsigned, biased binary exponent
final
floatingPointValue → FloatingPointValue
Return the FloatingPointValue
no setter
glitch → SynchronousEmitter<LogicValueChanged>
A stream of LogicValueChanged events for every time the signal transitions at any time during a Simulator tick.
latefinalinherited
hashCode → int
The hash code for this object.
no setterinherited
isArrayMember → bool
True if this is a member of a LogicArray.
no setterinherited
isInput → bool
Returns true iff this signal is an input of its parent Module.
no setterinherited
isOutput → bool
Returns true iff this signal is an output of its parent Module.
no setterinherited
isPort → bool
Returns true iff this signal is an input or output of its parent Module.
no setterinherited
leafElements → List<Logic>
A list of all leaf-level elements at the deepest hierarchy of this structure provided in index order.
latefinalinherited
mantissa → Logic
unsigned binary mantissa
final
name → String
The name of this signal.
finalinherited
naming → Naming
Controls the naming (and renaming) preferences of this signal in generated outputs.
no setterinherited
negedge → Stream<LogicValueChanged>
A Stream of LogicValueChanged events which triggers at most once per Simulator tick, iff the value of the Logic has changed from 1 to 0.
no setterinherited
nextChanged → Future<LogicValueChanged>
Triggers at most once, the next time that this Logic changes value at the end of a Simulator tick.
no setterinherited
nextNegedge → Future<LogicValueChanged>
Triggers at most once, the next time that this Logic changes value at the end of a Simulator tick from 1 to 0.
no setterinherited
nextPosedge → Future<LogicValueChanged>
Triggers at most once, the next time that this Logic changes value at the end of a Simulator tick from 0 to 1.
no setterinherited
packed → Logic
Packs all elements into one flattened bus.
latefinalinherited
parentModule ↔ Module?
The Module that this Logic exists within.
getter/setter pairinherited
parentStructure → LogicStructure?
If this is a part of a LogicStructure, the structure which this is a part of. Otherwise, null.
no setterinherited
posedge → Stream<LogicValueChanged>
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
Returns a version of this Logic with the bit order reversed.
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
final
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
valueBigInt → BigInt
The current valid active value of this signal as a BigInt.
no setterinherited
valueInt → int
The current valid active value of this signal as an int.
no setterinherited
width → int
The number of bits in this signal.

Methods

abs() → Logic
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.
override
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)
lt(dynamic other) → Logic
Less-than.
inherited
lte(dynamic other) → Logic
Less-than-or-equal-to.

inherited
mulAssign(dynamic val, {Logic s(Logic p1)?}) → Conditional
Multiply-assigns each element of elements using Logic.mulAssign.
inherited
neq(dynamic other) → Logic
Logical inequality.

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
toString() → String
A string representation of this object.
inherited

Unary XOR.
inherited
zeroExponent() → Logic
Return the zero exponent representation for this type of FloatingPoint
zeroExtend(int newWidth) → Logic
Returns a new Logic with width newWidth where new bits added are zeros as the most significant bits.
