PendingClockedDriver<SequenceItemType extends SequenceItem> class abstract

A type of PendingDriver that requires a clk and will wait for cycles on that clock for timeouts and drop delays.

Constructors

PendingClockedDriver(String name, Component? parent, {required Sequencer<SequenceItemType> sequencer, required Logic clk, int? timeoutCycles, int? dropDelayCycles, Edge waitEdge = Edge.pos, bool enableEndOfTestEmptyCheck = true})
Creates a new PendingClockedDriver attached to sequencer with the specified timeoutCycles and dropDelayCycles.

Properties

clk → Logic
The clock for this driver.
final
components → UnmodifiableListView<Component>
A List of all children Components.
no setterinherited
dropDelay → (Future<void> Function()?)
A function called each time an objection would drop due to an empty pendingSeqItems, but the objection will only be dropped if there is no further activity before it completes.
finalinherited
dropDelayCycles → int?
Number of cycles to hold an objection even when no items are pending.
final
enableEndOfTestEmptyCheck → bool
If true, will check at the end of the test that there are no pending items remaining to be driven.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
logger → Logger
A Logger for messages related to the test or testbench.
latefinalinherited
name → String
A name for this instance of the Component.
finalinherited
parent → Component?
The Component which constructed and contains this Component.
finalinherited
pendingSeqItems ↔ Queue<SequenceItemType>
A Queue of items that have been received from the sequencer and are waiting to be driven. After an item has been driven, it should be removed.
latefinalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sequencer → Sequencer<SequenceItemType>
The sequencer from which this Driver acquires new items to drive.
finalinherited
timeout → (Future<void> Function()?)
A function called each time there is something added or removed from the pendingSeqItems, and if it completes before an objection is dropped or some further activity occurs, an error is flagged.
finalinherited
timeoutCycles → int?
Number of cycles before triggering a timeout error.
final
waitEdge → Edge
The Edge to wait on when counting cycles for timeoutCycles and dropDelayCycles.
final

Methods

build() → void
Performs additional build-related activities required before run.
inherited
check() → void
Performs additional checks at the end of the simulation.
inherited
fullName() → String
A descriptive name including the full hierarchical path of this Component.
inherited
hierarchy() → List<Component>
Returns a List of Components representing the full hierarchy of this Component, with the top-most parent at index 0 and this as the last element of the List.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
run(Phase phase) → Future<void>
Executes this Component's activities related to running the test.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
