uvm_push_driver #(REQ,RSP)

Base class for a driver that passively receives transactions, i.e. does not initiate requests transactions.  Also known as push mode.  Its ports are typically connected to the corresponding ports in a push sequencer as follows:

push_sequencer.req_port.connect(push_driver.req_export);
push_driver.rsp_port.connect(push_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.

Base class for a driver that passively receives transactions, i.e.
Class Hierarchy
Class Declaration
class uvm_push_driver #(
    type  REQ  =  uvm_sequence_item,
    type  RSP  =  REQ
) extends uvm_component
Ports
req_exportThis export provides the blocking put interface whose default implementation produces an error.
rsp_portThis analysis port is used to send response transactions back to the originating sequencer.
Methods
newCreates 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.

req_export

This export provides the blocking put interface whose default implementation produces an error.  Derived drivers must override put with an appropriate implementation (and not call super.put).  Ports connected to this export will supply the driver with transactions.

rsp_port

This analysis port is used to send response transactions back to the originating sequencer.

new

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_void class is the base class for all UVM classes.
virtual class uvm_object extends uvm_void
The uvm_object class is the base class for all UVM data and hierarchical classes.
class uvm_report_object extends uvm_object
The uvm_report_object provides an interface to the UVM reporting facility.
virtual class uvm_component extends uvm_report_object
The uvm_component class is the root base class for UVM components.
class uvm_push_driver #( type  REQ  =  uvm_sequence_item,
type  RSP  =  REQ ) extends uvm_component
Base class for a driver that passively receives transactions, i.e.
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.
