The base class for drivers that initiate requests for new transactions via a uvm_seq_item_pull_port. The ports are typically connected to the exports of an appropriate sequencer component.
This driver operates in pull mode. Its ports are typically connected to the corresponding exports in a pull sequencer as follows:
driver.seq_item_port.connect(sequencer.seq_item_export); driver.rsp_port.connect(sequencer.rsp_export);
The rsp_port needs connecting only if the driver will use it to write responses to the analysis export in the sequencer.

Derived driver classes should use this port to request items from the sequencer. They may also use it to send responses back.
This port provides an alternate way of sending responses back to the originating sequencer. Which port to use depends on which export the sequencer provides for connection.
function new ( string name, uvm_component parent )
Creates and initializes an instance of this class using the normal constructor arguments for uvm_component: name is the name of the instance, and parent is the handle to the hierarchical parent, if any.
The uvm_object class is the base class for all UVM data and hierarchical classes.
virtual class uvm_object extends uvm_void
The uvm_report_object provides an interface to the UVM reporting facility.
class uvm_report_object extends uvm_object
The uvm_component class is the root base class for UVM components.
virtual class uvm_component extends uvm_report_object
The base class for drivers that initiate requests for new transactions via a uvm_seq_item_pull_port.
class uvm_driver #( type REQ = uvm_sequence_item, type RSP = REQ ) extends uvm_component
Creates and initializes an instance of this class using the normal constructor arguments for uvm_component: name is the name of the instance, and parent is the handle to the hierarchical parent, if any.
