avl_axi._mwakedriver module
- class avl_axi._mwakedriver.ManagerWakeDriver(*args, **kwargs)[source]
- Parameters:
name (str)
parent (Component)
- __init__(name, parent)[source]
Initialize the Manager Write Driver for the AXI agent.
- Parameters:
name (str) – Name of the agent instance
parent (Component) – Parent component
- Return type:
None
- status
Indication of current wake state
- pre_wakeup
Pre-wakeup delay - time to wait before driving the wakeup signal (0.0 - 1.0) (>= version 5)
- post_wakeup
Post-wakeup delay - time to wait after driving the wakeup signal (0.0 - 1.0) (>= version 5)
- async reset()[source]
Reset the driver by setting all signals to their default values. This method is called when the driver is reset.
By default 0’s all signals - can be overridden in subclasses to add randomization or other behavior.
- Return type:
None
- async wait_on_reset()[source]
Wait for the reset signal to go low and then call the reset method. This method is called to ensure that the driver is reset before driving any signals. It waits for the presetn signal to go low, indicating that the reset is active, and then calls the reset method to set all signals to their default values.
- Return type:
None
- async assert_wake(item)[source]
Assert wake for the given item. This method is called to assert the wake signal for the given item. It waits for the pre-wakeup delay, asserts the wake signal, and then waits for the post-wakeup delay before setting the item event to “awake”.
- Parameters:
item (SequenceItem) – The sequence item for which to assert wake
- Return type:
None
- async deassert_wake(item)[source]
Deassert wake for the given item. This method is called to deassert the wake signal for the given item. It waits for the item event “response” to be set, indicating that the item has been processed, and then deasserts the wake signal if there are no outstanding transactions.
- Parameters:
item (SequenceItem) – The sequence item for which to deassert wake
- Return type:
None
