Logic
Const

Constructors

Const(dynamic val, {int? width, bool fill = false}): Constructs a Const with the specified value.

Properties

arrayIndex → int?: If this is a part of a LogicArray, the index within that array. Othwerise, returns null.
read-onlyinherited
bit → LogicValue: The current active value of this signal if it has width 1, as a LogicValue.
read-onlyinherited
changed → Stream<LogicValueChanged>: A Stream of LogicValueChanged events which triggers at most once per Simulator tick, iff the value of the Logic has changed.
read-onlyinherited
dstConnections → Iterable<Logic>: An Iterable of all Logics that are being directly driven by this.
latefinalinherited
elements → List<Logic>: Provides a list of logical elements within this signal.
latefinalinherited
glitch → SynchronousEmitter<LogicValueChanged>: A stream of LogicValueChanged events for every time the signal transitions at any time during a Simulator tick.
read-onlyinherited
hashCode → int: The hash code for this object.
read-onlyinherited
isArrayMember → bool: True if this is a member of a LogicArray.
read-onlyinherited
isInput → bool: Returns true iff this signal is an input of its parent Module.
read-onlyinherited
isOutput → bool: Returns true iff this signal is an output of its parent Module.
read-onlyinherited
isPort → bool: Returns true iff this signal is an input or output of its parent Module.
read-onlyinherited
name → String: The name of this signal.
finalinherited
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.
read-onlyinherited
nextChanged → Future<LogicValueChanged>: Triggers at most once, the next time that this Logic changes value at the end of a Simulator tick.
read-onlyinherited
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.
read-onlyinherited
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.
read-onlyinherited
parentModule ↔ Module?: The Module that this Logic exists within.
read / writeinherited
parentStructure → LogicStructure?: If this is a part of a LogicStructure, the structure which this is a part of. Otherwise, null.
read-onlyinherited
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.
read-onlyinherited
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.
read-onlyinherited
reversed → Logic: Returns a version of this Logic with the bit order reversed.
read-onlyinherited
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited
srcConnection → Logic?: The Logic signal that is driving this, if any.
read-onlyinherited
structureName → String: Returns the name relative to the parentStructure-defined hierarchy, if one exists. Otherwise, this is the same as name.
read-onlyinherited
value → LogicValue: The current active value of this signal.
read-onlyinherited
valueBigInt → BigInt: The current valid active value of this signal as a BigInt.
read-onlyinherited
valueInt → int: The current valid active value of this signal as an int.
read-onlyinherited
width → int: The number of bits in this signal.

Methods

and() → Logic: Unary AND.
inherited
decr({Logic s(Logic)?, dynamic val = 1}) → Conditional: Shorthand for a Conditional which decrements this by val.
inherited
divAssign(dynamic val, {Logic s(Logic)?}) → Conditional: Shorthand for a Conditional which increments this by val.
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)?, dynamic val = 1}) → Conditional: Shorthand for a Conditional which increments this by val.
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
lt(dynamic other) → Logic: Less-than.
inherited
lte(dynamic other) → Logic: Less-than-or-equal-to.
inherited
makeUnassignable() → void: Makes it so that this signal cannot be assigned by any full (<=) or conditional (<) assignment.
inherited
mulAssign(dynamic val, {Logic s(Logic)?}) → Conditional: Shorthand for a Conditional which increments this by val.
inherited
neq(dynamic other) → Logic: Logical inequality.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
or() → Logic: Unary OR.
inherited
pow(dynamic exponent) → Logic: Power operation
inherited
put(dynamic val, {bool fill = false}) → void: Puts a value val onto this signal, which may or may not be picked up for changed in this Simulator tick.
inherited
replicate(int multiplier) → Logic: Returns a replicated signal using ReplicationOp with new width = this.width * multiplier The input multiplier cannot be negative or 0; an exception will be thrown, otherwise.
inherited
signExtend(int newWidth) → Logic: Returns a new Logic with 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
slice(int endIndex, int startIndex) → Logic: Accesses a subset of this signal from startIndex to endIndex, both inclusive.
inherited
toString() → String: A string representation of this object.
inherited
withSet(int startIndex, Logic update) → Logic: Returns a copy of this Logic with the bits starting from startIndex up until startIndex + update.width set to update instead of their original value.
inherited
xor() → Logic: Unary XOR.
inherited
zeroExtend(int newWidth) → Logic: Returns a new Logic with width newWidth where new bits added are zeros as the most significant bits.
inherited
