Constructors

function

new(string name, uvm_component parent = null)

Function

new

Standard component constructor that creates an instance of this class using the given name and parent , if any. IMPLEMENTATION

Parameters:

• name (string)

• parent (uvm_component)

Functions

virtual function void

stop_sequences()

Function

stop_sequences

Tells the sequencer to kill all sequences and child sequences currently operating on the sequencer, and remove all requests, locks and responses that are currently queued. This essentially resets the sequencer to an idle state. Function- stop_sequences

Tells the sequencer to kill all sequences and child sequences currently operating on the sequencer, and remove all requests, locks and responses that are currently queued. This essentially resets the sequencer to an idle state.
